IIMPORTANT SAFETY NOTICES

PREVENTION OF PHYSICAL INJURY 1. Before disassembling or assembling parts of the copier and peripherals, make sure that the copier power cord is unplugged. 2. The wall outlet should be near the copier and easily accessible. 3. Note that some components of the copier and the paper tray unit are supplied with electrical voltage even if the main power switch is turned off. 4. If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components. 5. If the Start key is pressed before the copier completes the warm-up period (the Start key starts blinking red and green alternatively), keep hands away from the mechanical and the electrical components as the copier starts making copies as soon as the warm-up period is completed. 6. The inside and the metal parts of the fusing unit become extremely hot while the copier is operating. Be careful to avoid touching those components with your bare hands. HEALTH SAFETY CONDITIONS 1. Never operate the copier without the ozone filters installed. 2. Always replace the ozone filters with the specified ones at the specified intervals. 3. Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eye drops or flush with water as first aid. If unsuccessful, get medical attention. OBSERVANCE OF ELECTRICAL SAFETY STANDARDS 1. The copier and its peripherals must be installed and maintained by a customer service representative who has completed the training course on those models. 2. The NVRAM on the system control board has a lithium battery which can explode if replaced incorrectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance with local regulations.
1. SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an open flame. 2. Dispose of used toner, developer, and organic photoconductors in accordance with local regulations. (These are non-toxic supplies.) 3. Dispose of replaced parts in accordance with local regulations. 4. When keeping used lithium batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.
LASER SAFETY
The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and laser subsystems to the factory or service depot when replacement of the optical subsystem is required.
!WARNING
Use of controls, or adjustment, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.
!WARNING
WARNING: Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser beams can seriously damage your eyes. CAUTION MARKING:

3. REPLACEMENT AND ADJUSTMENT

New design changes have been implemented in order to accommodate the new PxP (Polyester Polymerization) toner, which is of smaller particle size and allows lower fusing temperatures. This section describes some of these design changes and how they affect replacement and adjustment procedures. PCU New cleaning blade: The PCU (Photoconductor Unit) must handle finer toner, so in addition to the stationary drum cleaning blade, a spring-loaded blade has been added for drum cleaning. The additional cleaning blade is required for the finer toner, and a new procedure for removal has been added. ( Drum Cleaning Blade) Charge roller replacement: The standard voltages for SP2001 1 have changed and must be checked after charge roller replacement. Fusing Unit The fusing unit can be operated at a lower temperature for the finer toner because it melts easily, so the following changes have been made in the fusing unit: Cooling fans: Two cooling fans have been added around the fusing unit, one on the right side of the machine and another on the right corner. Two new removal procedures have been added. ( 3.4.2, 3.4.3) Hot roller knob: The size of the knob on the end of the fusing unit is larger, making the roller easier to turn manually. ( 3.4.1) Other Changes While the following are not related to the new toner, they are nonetheless important changes: Toner shield glass cover: The shield glass is now equipped with a cover that locks the glass in place and prevents the shield glass from sliding out of the machine accidentally. ( 3.2.2) Dust blades: Two new paper dust blades have been added around the registration roller to clean paper dust from the paper feed path. Both blades can be easily removed and cleaned. ( 3.5.1, 3.5.2) IOB: The IOB (I/O Interface Board) has been moved from inside the machine to under the rear lower cover, making access much easier. ( 3.6.1) Flash memory cards: The number designations for the flash memory cards have changed. (3.1.1)

USING THE DEBUG LOG
5.3 USING THE DEBUG LOG

This machine provides a Save Debug Log feature that allows saving and retrieving error information for later analysis. Every time an error occurs the debug information is recorded in volatile memory but is lost every time the machine is switched off and on. The Save Debug Log feature provides two new features: The customer or CE can save the debug log to HDD as soon as an error occurs. This is especially useful for recording information about errors that do not generate an SC code. The CE can copy the information to HDD and then to an IC card for later analysis. When an error occurs while the machine is operating, a debugging log is generated in memory but this log is lost as soon as processing resumes or after the machine is cycled off and on.
5.3.1 CAPTURING DEBUGGING INFORMATION

The machine must be setup up correctly with SP codes in order for the debug log to be captured for later retrieval. Otherwise, the debugging log is lost. The debug information cannot be saved the until the Save Debug Log function has been switched on and a target has been selected. 1. Enter the SP mode. Press ' then use the 10-key pad to enter !(). Press and hold down " for more than 3 seconds. Enter *+*) then press #. 2. Under 5857 Save Debug Log, press !.

5.3.2 RETRIEVING THE DEBUG LOG

Recording Errors Manually
When the machine issues an SC code in response to an error, or when a jam occurs, the error information is recorded in the debug log depending on how the system is set up with the procedures described above. However, information about undefined errors (errors that do not generate SC codes) that occur during copier operation or when printing from memory are not recorded automatically. Undefined errors not recorded automatically can be recorded on the HDD by following the simple manual procedure described below. NOTE: In order to use this procedure, the Save Debug Log feature must be switched on and the HDD or IC card must be selected as the target. 1. Make sure that the Save Debug Log feature is switched on. 2. When the error occurs, on the operation panel, press " (Reset). 3. On the 10-key pad, press 01 then press and hold down . until the machine beeps then release. 4. After completing Steps 1~3, to continue switch the machine off then on.
1. Insert the IC card into the copier. 2. Enter the SP mode and execute SP5857 007 (Copy HDD to IC Card (Latest 4 MB) to write the debugging data to the IC card. 3. The IC card can hold up to 4MB of data. If the debugging data is larger than 4MB, you can switch to another IC card.
Converting the Debug Log to Binary Data

1. Remove the IC card from the copier then insert it into the PC equipped with an IC card slot. 2. Start SwapBox. 3. Select Image> Read then click OK to start reading the data. 4. After confirming that the data has been read, select File> Save, then enter an appropriate file name and save the file. This completes converting the debugging log to binary data.

Analyzing the Debug Log Binary Data

The binary data created in the previous step must be sent to the Design Center for analysis. Since the amount of data can be fairly large (approximately 4 MB), compress the data with a standard compression program like ZIP or LZH and send it via email. If a PC and the software for converting the IC card data to binary is not available, you can send or deliver the IC card. A software application (GWLOG.EXE) is provided to convert the binary data file to a text file which can be read on screen or printed. On the DOS command line, type: C:\GWLOG<Path> and press ENTER. The <Path> is the path to the directory (folder) where the converted binary file created in the previous was saved. NOTE: 1) The program converts binary file to a text file in the same directory. 2) The target file name for the text file is generated automatically. 3) If the debug log was copied to an IC card of the wrong format, then an error is issued and the program halts.

The CCD converts the light reflected from the original into an analog signal. The CCD line has 7200 pixels at a resolution of 600 dpi. The CCD has two output lines to the analog processing ASIC, one for handling odd and one for handling even pixels. The analog processing ASIC performs the following operations on the signals received from the CCD: Z/C (Zero/Clamp): Adjusts the black level for even pixels to match the odd pixels. Signal composition: Analog signals for odd and even pixels from the CCD are merged by a switching device. Signal amplification: The analog signal is amplified by amplifiers in the AGC circuit. The maximum gains of the amplifiers are controlled by the CPU on the BICU board. After the above processing, the analog signals are converted to 8-bit signals by the A/D converter. This gives a value for each pixel on a scale of 256 shades of gray. Then, this data goes to the BICU via the SIB.

This mode prevents the background of an original from appearing on copies. The copier scans the auto image density detection area [A]. This corresponds to a narrow strip at one end of the main scan line, as shown in the diagram. As the scanner scans down the page, the IPU on the BICU detects the peak white level for each scan line, within this narrow strip only. From this peak white level, the IPU determines the reference value for A/D conversion for the scan line. Then, the IPU sends the reference value to the A/D controller on the SBU. When an original with a gray background is scanned, the density of the gray area is the peak white level density. Therefore, the original background will not appear on copies. Because peak level data is taken for each scan line, ADS corrects for any changes in background density down the page. As with previous digital copiers, the user can select manual image density when selecting auto image density mode and the machine will use both settings when processing the original.

6.2.6 SUMMARY OF IMAGE PROCESSING FUNCTIONS

Shading correction: Compensates for the possible differences in the amount of light at the edges and center of a scanned image caused by the scanner lens, or scatter among pixels of the CCD. Pre-Filter Background erase: Attempts to eliminate the heavy background texture from copies (newspaper print or documents printed on coarse paper). Elements below the selected threshold level are eliminated. Pre-Filter Smoothing: Reproduces halftones while reducing the incidence of moir which can occur as a result of compressing and then decompressing the image. Main scan magnification: Adjusts magnification to the desired level by processing adjusting multiple, adjacent pixels in the direction of main scanning. Adjustment of magnification in the sub scan direction is done by changing the scanning speed. Independent dot erase: Attempts to recognize and eliminate scattered, independent dots in copies. Processes only pixels of high density and eliminates those of low density. Filtering (MTF filter/smoothing): Performs mainly edge enhancement with the MTF filter. Performs smoothing only in the Photo mode. The matrix size of the filter is 9 pixels x 7 lines. Gamma () coefficient: Controls the image density for images processed with grayscaling. Copy density adjustment is achieved with special notch coefficient conversion. The best coefficient suited for the selected mode can be stored and adjusted as needed.
Grayscale processing: Performs reproduction of grayscales, using mainly error diffusion. (In the Photo mode, conducts processing with dithering.)

6.2.7 IMAGE PROCESSING STEPS AND RELATED SP MODES

Text Mode
The Text mode achieves quality reproduction of text and sharp lines and ignores background texture. Processing is conducted with a high resolution MTF filter; special processing with the coefficient prevents background reproduction and achieves the best reproduction of images with error diffusion. Because the Soft and Normal settings use a weak MTF filter, the quality of the image is improved with the elimination of moir. The Sharp selection uses an MTF filter stronger than that of the Normal setting, thus increasing the sharpness of lines.

IMAGE PROCESSING
Text/Photo Mode
Text/Photo mode achieves high quality reproduction of pictures with accurate grayscaling. Processing is conducted with the special coefficient which reproduces a wide range of grayscale. Compared with the Text mode, text reproduced in the Text/Photo mode appears lighter and textured backgrounds could appear on copies, but the incidence of moir is reduced with and edge detection filter. Because Photo Priority uses an MTF filter weaker than that of the Normal setting, the quality of the image is improved with the elimination of moir. The Text Priority selection uses an MTF filter stronger than that of the Normal setting, thus increasing the sharpness of lines.

Photo Mode
Photo mode emphasizes grayscale processing to achieve the best possible reproduction of photographs and eliminate moir by using the highest density and coefficient in the reproduction of grayscales and dithering. Print Photo performs smoothing and dithering for photos copied from magazines, newspapers, etc. The Normal selection uses a higher resolution setting and employs error diffusion but does not use smoothing to improve the appearance of text in photographs. Glossy photo paper employs MTF filter processing and error diffusion to copy glossy or matte photographs and achieves a low incidence of moir, thus reproducing copies of photographs of high resolution. For photo mode, the features used depend on which type of greyscale processing has been selected for Photo mode (either dithering and smoothing or error diffusion and MTF); this depends on the setting of SP 4904 001. Details are explained later in this section.

Pale (Low-Density Mode)

Pale achieves image quality comparable with Text mode, but of lower contrast. Pale employs an MTF filter stronger than that employed by the Text mode and uses a darker coefficient, thus increasing the incidence of copying textured backgrounds. Ideal for copying extremely thin originals. Soft employs an MTF filter weaker than Normal, thus achieving a softer image with less moir. Sharp employs an MTF filter stronger than that of Normal, thus increasing the sharpness of lines.

Generation Copy Mode

Generation Copy, based mainly on Text mode, aims to achieve the best reproduction of copied originals (so called generation copies or copies of copies). This mode 1) employs an MTF filter weaker than that of the Text mode to eliminate spurious dots, 2) uses the coefficient to smooth the image, and 3) uses generation processing to thicken thin lines. Soft employs an MTF filter weaker than the Normal setting to achieve a softer image with less moir. Sharp employs an MTF filter stronger than that for Normal to emphasize lines for better image quality.

These SP mode settings are provided to reduce the incidence of moir in the reproduction of images whose data signals have been compressed in the direction of the main scan. However, these SP adjustments can cause different effects in the reproduction of images depending on: Whether they contain areas shaded with dot screening (newspaper, magazine photos) Their reduction ratios. These adjustments can also cause blurring in the reproduction of images that contain: Low density dots Low contrast text characters Fine lines While filter processing is provided to reduce the incidence of moir generated from digital signals, you must always pay attention to how these adjustments affect text characters and fine lines.

6.2.9 BACKGROUND ERASE

SP4903 65 ~ 69 cut the background from around images scanned from an original of rough texture such as a newspaper or parchment. The larger the setting done for this SP, the more background drops out from behind the image or text. This SP mode setting for image processing executes separately from the ADS (Auto Image Density) function that is performed in the SBU to set the peak white level for scanning to eliminate background. For example, if this SP is set for 20, then the scanning data up to 20 is set to 0 and cut from the image. The range for this SP code adjustment is 0 ~ 255. The recommended range for a normal document is 0 ~ 60. An official document on rough texture paper would fall in the recommended range of 120 ~ 160. The correct setting for any original will vary with the texture and quality of the background, but remember that selecting a higher numbers for this setting will eventually lower the quality of the document or cause unexpected results.

Independent dot erase (set with the SP mode settings listed in the table below) remains in effect even when a Custom Setting is selected with the User Tools. Independent dot erase targets for elimination random, irregular shaped black dots on the surface of the original that would otherwise appear in the copy after scanning and printing. The strength of the application of this feature can be adjusted for each mode. The filter compares each pixel with the pixels around an area 7 pixels x 7 lines. If the sum of the pixels at the edges is smaller than the threshold value, the object pixel is changed to zero (white). depending on the strength of the SP mode setting. Setting a larger setting increases the number of dots erased, but if set too high, this SP can also remove small or fine text characters or even portions of large text characters.

Interactive SP Codes Overview
The tables in this section are for quick reference. For details about how each SP code operates and interacts with other SP settings, please refer to the sections that follow. Many of the SP codes used for image processing adjustments are interactive in that they exist as master and slave SPs. Use the master SP codes for gross adjustment. If you need to fine adjust a master setting, set the master setting to 0 to access its slave SP codes. NOTE: In the tables below, the master SP codes are set in bold type. The slave SP codes are indented and set in normal type. Keep the following points in mind while you are using these SP codes: The slave SP codes cannot be accessed until the master SP is set to 0. For the slave SP code settings to take effect, the master SP code must remain set to 0. If the master SP code is reset to any value other than 0, then the slave SP codes are disabled and their adjustments have no effect on image processing. If a master SP code is provided with both a Strength and Level (coefficient) adjustment, adjust the Strength setting first to achieve the approximate effect that you want, then do the Level adjustment.

Strengthening the MTF filter sharpens the edges of text characters and improves the appearance of low contrast text but can also cause moir to appear in photos on the same original. Conversely, weakening the MTF filter softens the edges of text characters and reduces the occurrence of moir but low contrast characters may fade. Strengthen or weaken the MTF filter for the Text mode only when necessary. Adjustment of the MTF filter coefficient performs very fine level adjustment of the applied strength of the MTF filter. Adjustment of the MTF filter strength greatly affects the rate of the change applied to the image. Basically, you should first just the MTF filter strength in 1 step increments without adjusting the coefficient to achieve nearly the effect you want, and then use the coefficient settings for fine adjustment. Coefficient and strength adjustments for main scan affect lines parallel to the direction of scanning [A]. Coefficient and strength adjustments for sub scan affect lines at right angles to the direction of scanning [B].

To access an SSP, enter the SP mode: press and hold down ! on the 10-key pad then Copy SP on the touch-screen. Filter Setting: Edge (Column 2): Provides filter processing of edges to improve the clarity of originals that contain text and lines. Selecting a larger value sharpens the clarity. However, increasing the value also increases the possibility of producing moir in the image. Filter Setting: All (Column 3): Provides filter processing for the overall image, not to improve just text, lines, or photographs, but to improve the image as a whole. This filter coefficient reduces the incidence of moir in images that contain shaded areas created with dots. Increasing the value improves reproduction of low contrast text and lines. However, increasing the value also increases the possibility of producing moir in the image. Filter Strength: Edge (Column 4): Aims to increase the strength of the Filter Setting: Edge effect that processes edges to improve the clarity of originals that contain text and lines. Increasing this setting not only increases the strength of the effect and creates thicker text characters and lines, but can also cause moir to appear in the image. On the other hand, decreasing this setting lessens the effect, creating thinner characters and lines and also reduces the incidence of moir. Filter Adj.: Edge Detection (Column 5): Broadens the range of the effect of the Filter Setting Edge SP. Lowering this setting broadens the range for edge filter processing and increases clarity. Also, using this SP together with Filter Adj. Mag. below can sharpen edges to an extent that an abnormal looking image is created.

Filter Adj.: Magnification (Column 6): Allows gradual adjustment of clarity in original images that contain varying degrees of clarity between text and lines, or between areas of the same image. Increasing these settings in large increments could easily cause moir to appear in the images. These settings should always be changed in small increments. Follow these general rules with these settings: Increasing the settings dramatically increases clarity but can also increase the incidence of moir. Reducing the settings produces a smoother image, reduces the incidence of moir, but also reduces the effect of the filters. Adjusting the Filter Adj. Mag. SPs in combination with other settings can even produce abnormal images. Also, SP4904 007 adjusts the error diffusion process that is used in text/photo mode.

Photo Mode Smoothing for Dithering

Strengthening this SP4903 37 (Smoothing Filter in Photo Mode) makes images smoother and reduces the occurrence of moir but can also cause fading. Strengthen this setting only when necessary. Only valid if SP 4901 001 is at 0.
Smoothing Coefficient SP4903 37 (Smoothing Filter in Photo Mode) Range 0~7
Photo Mode Grayscale

This SP mode adjustment sets how grayscales are processed when the user selects Photo mode on the operation panel. SP4904 1 Grayscale Photo Mode
Setting 0 1 Description Dithering and smoothing Error diffusion, MTF filter correction for edges
If 0 is selected, the image grayscales are processed with dithering and filter processing, just as they are processed with the Print Photo selection on the operation panel. In this case the filter processing means smoothing only. The filter coefficient for smoothing can be adjusted with SP4904 37 (Smoothing Filter in Photo Mode). If 1 is selected, then the image grayscales are processed with error diffusion processing, just as they are processed with the Normal and Glossy Photo settings on the operation panel. The MTF filter applied is the same as that applied for the Normal setting. To achieve better photo image quality with slightly less clarity in lines and text, select 0 for dithering. You can also adjust SP4904 2 to achieve better reproduction of photographs. On the other hand, to achieve better clarity in text and lines, with a slight sacrifice in the quality grayscale and smoothness in photographs, select 1 for error diffusion. To improve the clarity of fine lines and text, you can also increase the strength of the MTF filter. However, increasing the strength of the filter can also increase the incidence of moir in areas of newspaper, magazine, or other photographs created with dot screening.

Photo Mode Image Quality

This section describes how to select a setting to improve image quality in the Photo mode with dithering in order to create an extremely smooth photo image. Generally, a larger dithering matrix uses rougher dither pattern to reproduce a smoother gray image, but lowering the resolution can make text and lines more difficult to see. Conversely, a smaller dithering matrix uses a finer dithering pattern to reproduce a gray image of rougher texture, but raising the resolution can make text and lines easier to see. SP4904 002 Quality Photo Mode
Setting 0 1 2 3 Dither Pattern 8 x 8 (75 lines) 8 x 8 (106 lines) 6 x 6 (142 lines) 4 x 4 (212 lines) Picture Quality High Highest Medium Low Text Quality Low Low Medium High Processing Priority Dot screen areas Filled areas (highest priority) Default Filled areas Resolution
For these dither adjustments to take effect, SP4904 1 (Grayscale Photo Mode) must be set to 0 to enable dithering. Here are some general rules: If your main concern is reproducing legible text, use the smaller matrixes, but a smaller matrix could cause spurious lines to appear in images. When using the smallest matrix with setting 3 (4 x 4), you should switch off the smoothing filter for the Photo mode by setting SP4903 37 to 0. Use the largest dither matrix (setting 0) for originals that contain dot screening such as newspaper and magazine photographs.

Vertical Black Line Correction
This section describes how to select a setting to correct vertical black lines. SP4904 5 (Special Text Density) adjusts the overall intensity of the image to eliminate vertical black lines in originals caused by documents scanned on a copy machine with dirty optics.
SP Mode SP4904 5 Special Text Density Default 0 Range 0~7
Normally, the default setting (0) leaves this feature switched off. Select a higher setting to increase the effect or a lower setting to decrease the effect. High density vertical black lines may require a higher setting, but a higher setting could cause the overall density of the copy to lower, or could cause low density areas to drop out completely. NOTE: Generally, this SP code corrects most low density vertical black lines but may not be able to correct extremely dark or wide black lines.

Density Settings
This section describes how to adjust the density settings for the Pale mode Generation Copy mode, and Text mode. SP4904 3 is used to switch the density characteristics to binary digital processing for black and white originals to achieve better balance between text and images, correct shadows that appear around text in handwritten documents, to enhance documents written in pencil, or to achieve stark contrast when copying blueprints, building plans, etc. SP4903 3 Density Setting for Low Density Original Mode
Settings 0 1 Density Characteristics
Selects normal density (Default). Digitizes to near binary image.
SP4904 4 is used to switch between normal density and better reproduction of areas with graduated fill in originals copied in the Generation Copy mode. To improve the appearance of graduated fill areas of high density, set to 1 so the process can ignore black and more accurately reproduce areas with graduated fill. For example, the 1 setting is ideal for copying Generation Copy originals of medical charts that contain images of internal organs. SP4904 4 Density Setting for Copied Original Mode

ADS Level
This section shows you how to adjust the center notch for the ADS (Automatic Density Setting) level. The notches are not displayed during ADS adjustment. Of 7 steps (notches) the center notch is 4. This is the value adjusted with this SP code. SP5106 6 (ADS Level Selection) selects the image density used in ADS mode. For example, if you set SP5106 66 to 2, pressing the Auto Image Density key toggles the display off and manual notch 2 is selected. This SP code is adjusted, if the customer cannot attain clean copies after performing automatic density adjustment. This mode prevents the background of an original from appearing on copies. The copier scans the auto image density detection area, a narrow strip at one end of the main scan line. As the scanner scans down the page, the IPU on the BICU detects the peak white level for each scan line in this narrow strip only. The IPU uses this peak white level as a reference value for analog-to-digital conversion of the scan line, then the IPU sends the reference value to the A/D controller on the SBU. When an original with a gray background is scanned, for example, the density of the gray area becomes the peak white level density, so the original background will not appear on copies. Because peak level data is taken for each scan line, ADS corrects for any changes in background density down the page. As with previous digital copiers, the user can select manual image density when selecting auto image density mode and the machine will use both settings when processing the original.

The PxP (Polyester Polymerization) toner of this machine is of much finer particle size so in addition to the stationary cleaning blade, mounted with two screws at the bottom of the PCU, an additional cleaning blade [A] has been added to increase the efficiency of drum cleaning. The new cleaning blade is held in contact with the drum by two small springs [B] (one on each end) that keep the cleaning blade in contact with the drum. This cleaning blade is not a counter blade. Every time the PCU is opened for replacement or cleaning, the spring closest to the front of the PCU must moved in order to retract the cleaning blade away from the OPC drum. After cleaning or replacement, the spring must be returned to its original position to keep the blade in contact with the OPC drum for normal operation.

Mechanism
Black areas of the latent image are at a low negative charge (about 150 V) and white areas are at a high negative charge (about 950 V). To attract negatively charged toner to the [B] black areas of the latent image on the drum, the high voltage supply board [A] applies a bias of 510 volts to the development roller throughout the image development process. The bias is applied to the development roller shaft [B] through the bias terminal spring [C] and bias terminal [D]. The development bias voltage (-510 V) can be adjusted with SP2-201 (Development Bias).

B079D703.WMF
The registration drive roller [A] and idle roller [B] correct the skew of the paper to ensure that the leading edge of the paper is positioned correctly at the drum. The paper feed/development motor [C] drives the registration mechanism. The registration sensor [D] is positioned just before the registration rollers. When the leading edge activates the registration sensor, the registration clutch is switched off and the registration rollers stop turning. However, the relay clutch [E] remains on slightly longer. This delay allows more time for the paper to press against the registration rollers and buckle slightly to correct any skew. The registration sensor also detects misfeeds. Next, the registration clutch [F] actuates and the relay clutch at the correct time to align the paper with the image on the drum. The registration rollers then feed the paper to the image transfer section. Two new dust blades have been added around the registration roller. The idle roller dust blade [G] cleans the registration idle roller. This dust blade has a small dust box that collects paper dust that must be emptied periodically. The registration roller dust blade [H] cleans the registration roller. For details about how to remove and clean these new parts, see Section 3 Replacement and Adjustment.

IMAGE FUSING AND PAPER EXIT
6.6 IMAGE FUSING AND PAPER EXIT

6.6.1 CLEANING MECHANISM
[B]
[A]
B079D910.WMF
The cleaning roller [A], in constant contact with the pressure roller [B], collects toner and paper dust from the surface of the pressure roller. Because the cleaning roller is metal, it can collect adhering matter better than the pressure roller, which is coated with Teflon.
Some new design features have been implemented in order to cope with the lower temperatures required for new toner which has a melting temperature much lower than the previous toner. The cleaning roller [A] is composed of an aluminum shell with an internal heat pipe suspended in the middle of the roller to dissipate heat more rapidly.

6.6.2 HOT ROLLER STRIPPER CLEANING

After a job of more than the specified number of pages ends, the fusing/exit motor switches off and on to rotate the hot roller in order to dislodge toner clinging to the hot roller strippers. When printing ends, the fusing/exit motor switches off for 15 sec. then switches on for 15 sec. This on/off cycle is repeated for the number of times specified with SP3905 1 (Default: 1 off/on cycle). While the fusing/exit motor is switched off/on during the cleaning cycle, all fans remain on. NOTE: The hot roller strippers are also be force cleaned by adjusting and raising the setting of SP5959 (Image Timing Adjustment) which allows the drum and hot roller to turn freely to allow more time for cleaning before printing. However, make sure that the customer understands that increasing this SP setting slows down the first print time. These are the SP codes that control hot roller stripper cleaning. (For details, refer to Section 5. Service Tables.
No. SP3905 1 Name Number of Rotations Function Prescribes the number of times the hot roller is rotated at the end of the print job if the print job exceeds the number of pages specified with SP3905 2. (Default: 1) Prescribes the number of pages to print and trigger hot roller stripper cleaning. Cleaning executes only if the number of pages in the print job exceeds this number. (Default: 15 pp.)

Here are some important points to keep in mind about this new feature: If a request to start a print job is received during cleaning cycle in the timing chart above, cleaning stops and the new print job starts. During a normal print job, the fusing/exit motor switches on as soon as the paper reaches the registration roller, but in this case the fusing/exit motor remains on. If a request to enter the Off mode is received while hot roller stripper cleaning is in progress, the machine enters the Off mode and the cleaning cycle stops immediately. If the machine switches to any of the energy saver modes (low power mode, etc.) the cleaning cycle completes and does not halt. The cleaning cycle is not interrupted during free rotation of the hot roller when the machine is getting ready to print. Opening the front door, however, will stop the cleaning cycle.

6.6.3 FUSING TEMPERATURE CONTROL

[D] [C]
[B]
[A]
B079D913.WMF
The fusing unit has two fusing lamps: the first fusing lamp (center: 650W) [A] heats the center of the fusing roller, and the second fusing lamp (ends: 550W) [B] heats both ends of the hot roller. This arrangement ensures even heat on all surfaces of the roller. In order to control the temperature of the roller, two high response thermistors are attached to the unit, one near the center [C] and one at the end [D] of the hot roller.

B079D914.WMF
There are two types of temperature control: On/off control (Default) Phase control. Either mode can be selected with SP1104 (Fusing Temperature Control). After the machine is powered on, the CPU checks the ac frequency for 500 ms, in case phase control is selected later for the temperature control, and then switches on the fusing lamp. As soon as both the center and end thermistors detect the print ready temperature (also known as the re-load temperature), the machine can operate. The reload temperature is 3 C below the fusing temperature (this depends on the settings of SP1105 1~4, 7, 8). As soon as the thermistors detect the fusing temperature, the CPU switches the lamps off but frequently switches on/off again in order to maintain the fusing temperature. The default temperatures of SP1105 for these models are set 10 ~ 30 degrees lower than the temperatures for the previous machines. Some new SP codes have been added and others removed. For details, see Section 5. Service Tables.

Fusing Idling Temperature

If copies are not sufficiently fused soon after the main power switch is turned on, fusing idling should be enabled with SP1103 1. When fusing idling is enabled, it is done when the temperature reaches the print ready (re-load) temperature. The re-load temperature can be adjusted with SP1105 5,6. In the opposite case, even if fusing idling is disabled, it is done when the temperature at power-up 15 C The fusing idling time is as follows.
Temperature at power-on 15 C or less 0: Disabled 30 s Fusing Idling Mode 1: Enabled 30 s SP1103 1 SP1103 2

6.6.4 CPM DOWN FOR THICK PAPER

Because the fusing temperatures are set lower for the new toner which has a lower melting point, the results of printing on thick paper cannot be guaranteed at 45 cpm on the B082. Therefore, the 45 cpm line speed is adjusted down to 35 cpm as follows: After switching from Normal to Thick Paper for printing, the machine halts temporarily and re-starts for 35 cpm running. If the previous job included stapling or other finisher processing, these settings remain in effect for the next job on thick paper after the line speed is adjusted. If the print job on thick paper does not include an image on the page (a cover), then the speed is not adjusted down from 45 cpm to 35 cpm. NOTE: The previous machine automatically reduced line speed 30% (ppm down) for thick paper. In these models, however, the speed is reduced from 45 cpm to 35 cpm for the 45 cpm machine. This adjustment is performed automatically for the B082 (45 cpm) machine only. Note these other important points regarding cpm down for thick paper on the 45 cpm machine: When the line speed switches from 45 cpm to 35 cpm for thick paper, the transfer current changes to the settings specified with SP2301 (Transfer Current Adjustment). (For details, see Section 5. Service Tables.) Bias voltage, development and other settings are not affected. Fusing temperature adjustment switches on, but no operation can start until the machine reaches the temperature specified for the job. The ID sensor pattern is created and the line speed remains the same until the end of the job. The intensity of the LD unit is lowered evenly, 30 steps from its specified value.

6.6.5 COOLING AND OVERHEAT PROTECTION
[A]
[B]
B079D722.WMF
The fusing unit operates at temperatures lower than the previous model in order to accommodate the new toner which has a lower melting temperature. In order to further ensure cooler running temperatures for the fusing unit, two cooling fans have been added. The side cooling fan [A] and corner cooling fan [B] switch on when the temperature of the fusing unit exceeds 150 C and switch off when the main motor switches off. If the hot roller temperature exceeds 230 C for 5 seconds or more, the CPU cuts off the power to the fusing lamp, and SC543 (Fusing Overheat Error) will be displayed. Even if the thermistor overheat protection fails, there is a thermostat in series with the common ground line of the fusing lamp. If the temperature of the thermostat reaches 210 C, the thermostat opens, removing power from the fusing lamp. At the same time, the copier stops operating. At this time, SC542 (Fusing Temperature Warm-up Error) will be displayed.
