1173SBG0400A
Before using any consumables, always read the label on the container carefully. Use the right toner. The applicable copier model name is indicated on the Toner Bottle. Paper can to be easily damaged by dampness. To prevent absorption of moisture, store paper, which has been removed from its wrapper but not loaded into the drawer, in a sealed plastic bag in a cool, dark place. Keep consumables out of the reach of children. Do not touch the PC Drum with bare hands. Store the paper, toner, and other consumables in a place free from direct sunlight and away from any heating apparatus. The same sized paper is of two kinds, short grain and long grain. Short grain paper should only be fed through the copier crosswise, long grain paper should only be fed lengthwise. If your hands become soiled with toner, wash them with soap and water immediately. Do not throw away any used consumables (PC Drum, starter, toner, etc.). They are to be collected.
NOTE Do not burn, bury in the ground, or throw into the water any consumables (PC Drum, starter, toner, etc.).

1. PC Drum The PC Drum is an aluminum cylinder coated with a photosensitive semiconductor. It is used as the medium on which a visible developed image of the original is formed. (For more details, see 9. PC DRUM.) 2. Drum Charging The PC Drum Charge Corona Unit is equipped with a Comb Electrode and a Scorotron Grid to deposit a uniform negative charge across the entire surface of the PC Drum. (For more details, see 10. DRUM CHARGING.) 3. Image Erase Any areas of charge which are not to be developed are neutralized by lighting up LEDs. (For more details, see 11. IMAGE ERASE LAMP.) 4. Exposure Light from the Exposure Lamp reflected off the original is guided to the surface of the PC Drum and reduces the level of the negative charges, thereby forming an electrostatic latent image. (For more details, see 12. OPTICAL SECTION.) 5. Developing Toner positively charged in the Developer Mixing Chamber is attracted onto the electrostatic latent image changing it to a visible, developed image. A DC negative bias voltage is applied to the Sleeve/Magnet Roller to prevent toner from being attracted onto those areas of the PC Drum which correspond to the background areas of the original. (For more details, see 14. DEVELOPMENT.)
M-2
6. Paper Feeding Paper is fed either automatically from the 1st or 2nd Drawer, or manually via the Multi Bypass Table or Manual Bypass Table. Paper separation is accomplished by the torque limiter fitted to the Paper Separator Roll. (For more details, see 16. PAPER TAKE-UP/FEED SECTION.) 7. Image Transfer The single-wire Image Transfer Corona Unit applies a DC negative corona emission to the underside of the paper, thereby attracting toner onto the surface of the paper. (For more details, see 19. IMAGE TRANSFER AND PAPER SEPARATION.) 8. Paper Separation The single-wire Paper Separator Corona Unit applies an AC corona emission to the underside of the paper to neutralize the paper. In addition, mechanical paper separation is provided by the two PC Drum Paper Separator Fingers fitted to the Imaging Unit. (For more details, see 19. IMAGE TRANSFER AND PAPER SEPARATION.) 9. Cleaning Residual toner on the surface of the PC Drum is scraped off by the Cleaning Blade. (For more details, see 22. CLEANING UNIT.) 10. Main Erase Light from the Main Erase Lamp neutralizes any surface potential remaining on the surface of the PC Drum after cleaning. (For more details, see 20. MAIN ERASE LAMP.) 11. Transport The paper is fed to the Fusing Unit by the Suction Belts. (For more details, see 23. PAPER TRANSPORT.) 12. Fusing The developed image is permanently fused to the paper by a combination of heat and pressure applied by the Upper and Lower Fusing Rollers. (For more details, see 24. FUSING UNIT.) 13. Paper Exit After the fusing process, the paper is fed out by the Paper Exit Roller onto the Copy Tray. (For more details, see 25. EXIT UNIT.)

The watchdog function monitors whether any of the CPUs mounted in the copier overrun. If this function detects that a CPU overruns, the copier automatically resets the CPU, thereby restarting the logic circuit and mechanism. Even if a copier CPU operates erratically due to electrical noise, therefore, the copier is able to recover from the faulty condition so that the number of visits made by the Technical Representative for CPU overrun can be minimized.
1173SBM0501A
5-1.
Configuration
The copier has one printed-circuit board on which a CPU is mounted. That is the Master Board which has the following three CPUs: Master CPU: Controls the copier, Paper Feed Cabinet and Duplex Unit. SCP CPU: Controls the optical system. MSC CPU: Controls the control panel and system. In addition to these, each of the control boards for the Data Controller, Duplexing Document Feeder, and Sorter/Staple Sorter is equipped with a CPU. The watchdog functions are summarized as follows: Each of the copier CPUs monitors whether or not it overruns. The MSC CPU monitors the communications conditions of the CPUs in the Duplexing Document Feeder and Data Controller. The Master CPU monitors the communications conditions of the CPUs in the Sorter and Staple Sorter. The control boards for the Paper Feed Cabinet and Duplex Unit do not have a CPU in them. Instead, the Master CPU in the copier controls their operations.

The following processing is performed if a faulty condition is detected in the CPU. When the copier CPU is found faulty: All CPUs including those of the options are reset and the system is restarted. If the CPU is found faulty during a copy cycle, the system attempts to feed all sheets of paper out of the copier before resetting. (If paper is left inside the copier, the copier detects it as a misfeed as it is restarted.) When an option CPU is found faulty: The option relays are turned OFF and ON and all options are then restarted. If the CPU is found faulty during a copy cycle, the copier stops the paper take-up sequence and feeds all sheets of paper out of the copier before resetting. The Watchdog Counter available from the Tech. Rep. mode allows the Technical Representative to check if any faulty condition has occurred in the CPU. For details, see SWITCHES ON PWBs.

1173SBM0600A
When a malfunction occurs in the copier, the malfunction bypass function permits the copier to continue operating if that malfunction is one of the predefined candidates for an isolated malfunction and if it will not affect the current copying operation. But, if an isolated malfunction occurs anytime during the actual copy cycle, the copier considers it a normal malfunction. If a copying function involving an isolated malfunction is selected, the message Selected mode cant be used. appears on the Touch Panel and the copier rejects that function. When an isolated malfunction occurs, a tiny wrench indicator appears in the lower left corner of the Basic Screen. Access the Machine Status display by touching the icon or via the Tech. Rep. mode to ascertain the trouble code. Then refer to the Troubleshooting Manual for details. Trouble codes for up to five isolated malfunctions are shown on the Machine Status display. When a sixth isolated malfunction occurs, the copier considers it a normal malfunction, prompting a Tech. Rep. call. (The sixth malfunction is shown on the Touch Panel.) But, if all of the paper feed ports (except the manual feed port) show an isolated malfunction, the copier considers them a normal malfunction even though the isolated malfunction count may be less than five. The display also tells the condition when the image stabilization controls are not properly working.

The following are the details of each image stabilization control. 1-1. AIDC Sensor coarse adjustment This adjustment represents a coarse adjustment of the AIDC Sensor when the ordinary control of only the LED current cannot cover part-to-part variations in the AIDC Sensor (installation, circuit, deterioration, etc.). The surface of the PC Drum whose charges have been neutralized is exposed to light from the LED. The output current from the AIDC Sensor goes through the load resistance selected by a 4-bit analog switch and the 4-bit analog switch selects the load resistance so that the resultant voltage becomes 1V or less. 1-2. AIDC Sensor fine adjustment If the AIDC Sensor is dirty with toner, it results in an error being produced in the sensor output voltage value, providing a false reference value. The surface of the PC Drum which has been erased is exposed to light from the LED. The LED current value is varied through pulse width control so that the output voltage from the AIDC Sensor becomes 1V.

2. Grid voltage and T/C correction The Image Erase Lamp produces a solid-black pattern on the surface of the PC Drum and the AIDC Sensor reads the pattern. The grid voltage is then varied so that the output from the AIDC Sensor remains a given level or higher, which ensures that the toner-to-carrier ratio on the surface of the PC Drum becomes constant. If an even greater solid-black density is required when the upper control limit of the grid voltage has already been reached, the target control value of T/C is raised in 0.5% steps up to 7%, thus terminating the adjustment sequence. Control Value Grid Voltage 550 to 790V 1 Step 30V Initial Value 550V

<Relation with Image Density> The Image Exposure function of Tech. Rep. Choice available from the Tech. Rep. mode enables fine-adjustments of the grid voltage (solid-black image density) to be made. It specifies how many volts the optimum grid voltage determined by the image stabilization control is to be increased or decreased. This fine-adjustment value remains the same even when the optimum grid voltage is later varied by the image stabilization control.

3. Optimum Exposure Lamp voltage correction The Exposure Lamp is turned ON to illuminate the halftone patch on the back of the Original Width Scale, thereby producing a halftone pattern on the surface of the PC Drum. The Exposure Lamp voltage is then varied so that the output from the AIDC Sensor falls within the target range, thereby ensuring an optimum exposure level. Control Value Exposure Lamp voltage (100V Areas) Exposure Lamp voltage (200V Areas) 47 to 75V 94 to 140V 1 Step 1V 2V Initial Value 58V 116V
<Relation with Manual Exposure Level of F5> The manual exposure level of Function F5 available from the Tech. Rep. mode enables fine-adjustments of the Exposure Lamp voltage (halftone image density) to be made. It specifies how many volts the optimum Exposure Lamp voltage determined by the image stabilization control is to be increased or decreased. This fine-adjustment value remains the same even when the optimum Exposure Lamp voltage is later varied by the image stabilization control.

4. AE Sensor gain adjustment The Exposure Lamp is turned ON to illuminate the blank sheet of paper placed on the Original Glass (when an F5 or FF operation is run) or the halftone patch on the back of the Original Width Scale (when AE Sensor gain is adjusted in a sequence other than F5 or FF). The reflected light is then read by the AE Sensor and a gain adjustment of the AE Sensor is made to maintain an optimum Auto exposure level.

The copier is provided with a toner recycling mechanism. The toner, which has been scraped off the surface of the PC Drum by the Cleaning Blade and collected in the Cleaning Unit, is conveyed by the two Toner Recycling Coils to the Toner Supply Port and, from there, it is returned back to the Developer Mixing Chamber of the Developing Unit. One of the gears of the Toner Recycling mechanism receives drive through a gear at the rear end of the PC Drum. Toner Supply Port Toner Recycling Coil

PC DRUM
The photoconductive drum used in this copier is the organic photoconductor (OPC) type. The drum is made up of two distinct, semiconductive materials on an aluminum alloy base. The outer of the two layers is called the Charge Transport Layer (CTL), while the inner layer is called the Charge Generating Layer (CGL). The PC Drum has its grounding point inside at the rear end. When the Imaging Unit is installed in the copier, the shaft on which the PC Drum Drive Coupling Gear is mounted contacts this grounding point. Handling Precautions This photoconductor exhibits greatest light fatigue after being exposed to light over an extended period of time. It must therefore be protected from light by a clean, soft cloth whenever the Imaging Unit has been removed from the copier. Further, use utmost care when handling the PC Drum to prevent it from being contaminated. PC Drum Cross-Sectional View CTL PC Drum CGL Aluminum Cylinder

DRUM CHARGING
The PC Drum Charge Corona has a Scorotron grid to deposit a negative DC charge evenly across the surface of the PC Drum. The grid voltage (VG) applied to the grid mesh is selected between 550V (initial value, variable according to image stabilization controls) in the normal mode and the value in the normal mode +90V in the Photo mode by the Constant-Voltage Circuit in the High Voltage Unit. The Corona Unit has a Comb Electrode which minimizes the amount of ozone produced. The conventional wire type corona unit produces a large amount of ozone due to corona discharge in radial directions. The comb electrode type, on the other hand, discharges only toward the Grid Mesh, meaning a reduced amount of ozone is produced. The Comb Electrode can be cleaned by the user who pulls out to the front the shaft on which a Cleaning Roller is mounted. Holder Comb Electrode Spring Holder

In the Auto Exposure Mode, the AE Sensor on AE Sensor Board measures the intensity of the light reflected off the original, by sampling the black/white ratio of a 210-mm-wide area of the original being measured. According to this measurement, the Exposure Lamp voltage is automatically increased or decreased so that copies of consistent quality are produced. The output from the AE Sensor is applied to the Master Board which, in turn, varies the duty ratio of the AVR Remote which varies the Exposure Lamp voltage accordingly.

DEVELOPMENT
The Developing Unit built into the Imaging Unit performs the following functions: Mixes the toner and carrier well to ensure that a sufficient amount of toner is positively charged. Detects the toner-to-carrier ratio of the developer by means of the ATDC Sensor and replenishes the supply of toner as necessary. Detects a toner empty condition by means of the ATDC Sensor.

Value to the original value before the board was replaced.
M-39
Toner Empty Detection The copier has no toner empty detecting sensor and, instead, the ATDC Sensor performs that function. The ATDC Sensor checks the toner-to-carrier ratio and, if it reads a T/C ratio lower than the reference level for 37 copies and, further, if it next reads a ratio 1% lower than the reference level, this is a toner-empty condition. The toner-empty condition is canceled after detection under any of the following conditions when the Front Door is swung open and closed: T/C is 4% or more: The toner-empty condition is canceled. T/C is less than 4%: The copier initiates an Auxiliary Toner Replenishing sequence and cancels the toner-empty condition as soon as T/C reaches 4.5%. In addition, if the Tech. Rep. Choice setting has been made to inhibit the initiation of a new copy cycle in a toner-empty condition, the copier permits the initiation of a new copy cycle as soon as T/C reaches 4.0%.

The paper take-up and feeding mechanism takes up paper from the drawer and feeds it to the Vertical Transport Roller. The take-up mechanism is driven by 1st/2nd Drawer Paper Take-Up Motor. Each paper take-up mechanism consists of a Paper Take-Up Roll, Feed Roll and Separator Roll with torque limiter. The Separator Roll is controlled by the torque limiter so that it will not transport more than one sheet of paper at a time.

The paper separating mechanism ensures that only the top sheet of paper is fed in by separating the second sheet of paper from the top one. This is accomplished by the difference in friction coefficient between the first and second sheets of paper.
<Normal Feeding> Feed Roll Paper Separator Roll
4425M012AA
Driven or stationary
When only one sheet of paper is fed, the friction coefficient on the top side of the paper is equal to that on the underside. Driven by the Feed Roll, the paper drives the Separator Roll. This causes the paper to be sent to the Vertical Transport Section. The friction coefficient varies for different ambient conditions and types of paper being used, which often causes the Separator Roll to be stationary.
<Double Feeding> Feed Roll 1st sheet of Paper 2nd sheet of Paper Separator Roll
4425M013AA
Stopped
Since the coefficient of friction between the top side of the first sheet of paper and the Feed Roll is greater than that between the first and second sheets of paper, the first sheet of paper is fed into the copier by the Feed Roll. Since the friction coefficient between the second sheet of paper and the Separator Roll is greater than that between the first and second sheet of paper, the Separator Roll is not driven and holds the second sheet of paper.

If the drawer is pulled out while the paper is between the Feed Roll and the Separator Roll, the paper is left in the copier. Removal of the paper is difficult. With this copier, sliding out the drawer automatically disengages the paper and Paper Take-Up/Feed Roll. The Paper Pressure Releasing Mechanism makes it easier to remove a sheet of paper held between the Feed Roll and Paper Separator Roll by just sliding out the drawer. When the drawer is pulled out, the pressure release rail pushes down the Separator Roll Assy, disengaging the Feed Roll from the Separator Roll.

To minimize the occurrence of paper misfeed due to a slippery Paper Take-Up Roll, the Paper Take-Up Motor is kept deenergized for a given period of time before it is energized again, if a sheet of paper fails to reach the Paper Take-Up Sensor even after the lapse of a given period of time after the motor has first been energized. (This is referred to as the paper take-up retry function.) A misfeed results if the sheet of paper does not reach the Paper Take-Up Sensor even after three paper take-up sequences.
1173SBM160703A
The Paper Feed Roll and Separator Roll may sometimes fail to separate the subsequent sheet of paper properly and the leading edge of that paper may be beyond the Feed and Separator Rolls inside the copier. If the next paper take-up sequence is started in this condition, the distance between the preceding and the current sheet of paper will become shorter than normal, resulting in a misfeed. To maintain a given paper take-up interval, therefore, this copier provides the following control. If it takes the paper more than a specified time to block (L) the Paper Take-Up Sensor after the Paper Take-Up Motor has been energized, the Paper Take-Up Motor is temporarily deenergized and, an appropriate period of time thereafter, it is energized again (paper take-up interval control).
1173SBM160704A
Even if the Paper Take-Up Roll takes up two sheets of paper at one time, the double feed paper take-up control uses the second sheet of paper for the next copy cycle without causing a paper misfeed. It eliminates a paper misfeed that would otherwise result when two sheets of paper are taken up at once. If the second sheet of paper is stationary blocking the Paper Take-Up Sensor when the trailing edge of the first sheet of paper moves past the Vertical Transport Sensor, the copier determines that it is a double feed condition and provides double feed control. (The first drawer does not have double feed paper take-up control.) If, however, the second sheet of paper has reached the Vertical Transport Roller, the double feed control is not provided since the paper is fed further into the copier by the Vertical Transport Roller. This could result in a paper misfeed or the second sheet of paper being fed through the copier with the first one.

SYNCHRONIZING ROLLERS
The Synchronizing Rollers, operating in phase with the Scanner scan motion and paper feeding, synchronize the leading edge of the copy paper accurately with the leading edge of the toner image on the PC Drum. The Upper Synchronizing Roller is a metal roller covered with a polyvinyl chloride tubing, while the Lower one is a rubber roller. Upper Synchronizing Roller Synchronizing Roller Clutch CL1
To facilitate clearing of misfeeds, the Upper Synchronizing Roller is installed in the Imaging Unit. It is fitted to the Guide Frame of the Imaging Unit and the Compression Springs at the front and rear ends press the Roller downward so that it makes contact with the Lower Synchronizing Roller. The Lower Roller is driven by the drive source, while there is a gear train that transmits the rotation of the Lower Roller to the Upper Roller, thus ensuring good paper transport performance. To ensure good image transfer during conditions of high humidity, the Pre-Synch Guide Plate is electrically floated by a plastic spacer, grounded through an 82MW resistor and 1kV varistor.

Image Transfer The Image Transfer Corona applies a DC negative corona emission to the underside of the paper thereby attracting the positively charged toner onto the surface of the paper to form a visible, developed image of the original. The Corona Unit is provided with a Corona Wire cleaning mechanism: the operator has only to pull out the Lever on which the Cleaner is mounted from the front of the copier, which cleans the Wire. Paper Separation The Paper Separator Corona showers the underside of the paper with both positive and negative charges so that the paper can be easily separated from the PC Drum. In addition, two Paper Separator Fingers physically peel the paper off the surface of the PC Drum. (For details, see PAPER SEPARATOR FINGERS.) The Image Transfer/Paper Separator Coronas Unit is provided with a Pre-Image Transfer Guide Plate that determines the angle at which the paper comes into contact with the PC Drum and keeps an optimum distance between the paper and the PC Drum so that the image may be properly transferred onto the paper. The Image Transfer/Paper Separator Coronas Unit is grounded via a 2.6MW resistor, which improves its efficiency to discharge to the PC Drum side, thus reducing the output current from the High Voltage Unit.

After image transfer, an AC corona emission is applied to the underside of the paper by the Paper Separator Corona to neutralize the paper so that it can be easily separated from the PC Drum. To further ensure that the paper is positively separated from the PC Drum, there are two Paper Separator Fingers attached to the Imaging Unit. They physically peel the paper off the surface of the PC Drum. To prevent the Paper Separator Fingers from damaging the surface of the PC Drum, they are kept in the retracted position whenever they are not at work. As illustrated below, the Fingers are brought into contact with, and retracted from, the surface of the PC Drum by the Lever which is operated by the Separator Solenoid.

MEMORY BACKUP
IC1 (RAM) of the RAM Board connected to the Master Board stores the setting/adjustment values set in the Tech. Rep. Modes as well as the counter counts. The Backup Battery is mounted on the RAM Board to prevent the contents of memory from being lost when the power cord is unplugged or the RAM Board removed from the copier. Backup Battery requires a voltage of 2V or more to retain the contents of memory. Important As noted above, the RAM stores critical data. If the RAM Board has been replaced with a new one, memory must first be cleared and then all settings be made again. It should also be noted that the RAM Board should not be replaced at the same time when the Master Board is replaced.

SERVICE INSTRUCTIONS
INSTRUCTIONS FOR HANDLING THE PWBs WITH MOS ICs
The following precautions must be observed when handling P.W. Boards with MOS (Metal Oxide Semiconductor) ICs. During Transportation/Storage: During transportation or when in storage, new P.W. Boards must not be indiscriminately removed from their protective conductive bags. Do not store or place P.W. Boards in a location exposed to direct sunlight. When it becomes absolutely necessary to remove a Board from its conductive bag or case, always place it on its conductive mat in an area as free as possible from static electricity. Do not touch the pins of the ICs with your bare hands. During Replacement: Before unplugging connectors from the P.W. Boards, make sure that the power cord has been unplugged from the outlet. When removing a Board from its conductive bag or conductive case, do not touch the pins of the ICs or the printed pattern. Place it in position by holding only the edges of the Board. Before plugging connectors into the Board, make sure that the power cord has been unplugged from the power outlet. During Inspection: Avoid checking the IC directly with a multimeter; use connectors on the Board. Never create a closed circuit across IC pins with a metal tool. When it is absolutely necessary to touch the ICs and other electrical components on the Board, be sure to ground your body.
1-2.
During Transportation/Storage: Use the specified carton whenever moving or storing the PC Drum. The storage temperature is in the range between 20C and +40C. In summer, avoid leaving the PC Drum in a car for a long time. Handling: Ensure that the correct PC Drum is used. Whenever the PC Drum has been removed from the copier, store it in its container or protect it with a Drum Cloth. The PC Drum exhibits greatest light fatigue after being exposed to strong light over an extended period of time. Never, therefore, expose it to direct sunlight. Use care not to contaminate the surface of the PC Drum with oil-base solvent, fingerprints, and other foreign matter. Do not scratch the surface of the PC Drum. Do not apply chemicals to the surface of the PC Drum. Do not attempt to wipe clean the surface of the PC Drum.
D-1
If, however, the surface is contaminated with fingerprints, clean it using the following procedure. 1. Place the PC Drum into one half of its container.
1076D001
1076D002
2. Gently wipe the residual toner off the surface of the PC Drum with a dry, Dust-Free Cotton Pad. A. Rotate the PC Drum so that the area of its surface on which the line of toner left by the Cleaning Blade is present is facing straight up. Wipe the surface in one continuous movement from the rear edge of the PC Drum to the front edge and off the surface of the PC Drum. B. Rotate the PC Drum slightly and wipe the newly exposed surface area with a CLEAN face of the Dust-Free Cotton Pad. Repeat this procedure until the entire surface of the PC Drum has been thoroughly cleaned. At this time, always use a CLEAN face of the dry Dust-Free Cotton Pad until no toner is evident on the face of the Pad after wiping.
1076D003
1076D004
3. Soak a small amount of either ethyl alcohol or isopropyl alcohol into a clean, unused Dust-Free Cotton Pad which has been folded over into quarters. Now, wipe the surface of the PC Drum in one continuous movement from its rear edge to its front edge and off its surface one to two times. Never move the Pad back and forth.
4. Using the SAME face of the Pad, repeat the procedure explained in the latter half of step 3 until the entire surface of the PC Dru has been wiped. Always OVERLAP the areas when wiping. Two complete turns of the PC Drum would be appropriate for cleaning.
D-2
NOTES The Organic Photoconductor Drum is softer than CdS and Selenium Drums and is therefore susceptible to scratches. Even when the PC Drum is only locally dirtied, wipe the entire surface. Do not expose the PC Drum to direct sunlight. Clean it as quickly as possible even under interior illumination. If dirt remains after cleaning, repeat the entire procedure from the beginning one more time.
D-3
1-3.
(1) Screws Purpose of Application of Red Paint Red paint is applied to the screws which cannot be readjusted, set, or reinstalled in the field. The basic rule is not to remove or loosen the screws to which red paint is applied. In addition, be advised that, if two or more screws are designated as those which must not be touched on a single part, only one representative screw may be marked with red paint.
(2) Variable Resistors on Board Do not turn the variable resistors on boards for which no adjusting instructions are given in ADJUSTMENT.
(3) Other Screws Lower Pre-Image Transfer Guide Plate (2 screws) Lens Rail height setting screws (2)

INTRODUCTION
General Precautions
1. When servicing the copier with its covers removed, use utmost care to prevent your hands, clothing, and tools from being caught in revolving parts including the chains and gears. When servicing the copier with the Lower Rear Cover removed, be sure to install the jig. 2. Before attempting to replace parts and unplug connectors, make sure that the power cord of the copier has been unplugged from the wall outlet. 3. Never create a closed circuit across connector pins except those specified in the text and on the printed circuit. 4. When creating a closed circuit and measuring a voltage across connector pins specified in the text, be sure to use the green wire (GND). 5. When the user is using a word processor or personal computer from a wall outlet of the same line, take necessary steps to prevent the circuit breaker from opening due to overloads. 6. Keep all disassembled parts in good order and keep tools under control so that none will be lost or damaged.
1-2.
1. If a component on a PWB or any other functional unit including a motor is defective, the text only instructs you to replace the whole PWB or functional unit and does not give troubleshooting procedures applicable within the defective unit. 2. All troubleshooting procedures contained herein assume that there are no breaks in the harnesses and cords and all connectors are plugged into the right positions. 3. For the removal procedures of covers and parts, see DIS/REASSEMBLY, ADJUSTMENT. 4. The troubleshooting procedures are given in the order of greater frequency of trouble or order of operation. 5. The procedures preclude possible malfunctions due to noise and other external causes.
1-3.
1. The paper transport failure troubleshooting procedures are given according to the symptom. First identify the location where the paper is present and start the procedure for that particular location. For malfunction troubleshooting, start with step 1 and onward. 2. Make checks in numerical order of steps and, if an item is checked okay, go to the next step. Pattern 1 Step Check Item 1 2 Is--? Result YES Action Do this. Pattern 2 Step Check Item 1 2 Is--? Result YES NO Action Do this. Check that.

To allow the Tech. Rep. to easily and safely determine whether a particular controlled part is fully operational, this copier provides the following provision: checking the data of the I/O port of the board IC with the copier in the standby state (including a misfeed, malfunction, and closure failure condition) allows the Tech. Rep. to determine whether a signal is properly input to, and output from, a controlled part.
<Procedure> 1. On the circuit diagram accompanying the text, locate the I/O port of the controlled part which is probably defective when a misfeed or malfunction occurs. 2. Select the IC Port Data Check function of I/O Check in the Tech. Rep. mode and access the screen which contains the port identified in step 1 above. (See SWITCHES ON PWBs/TECH. REP. MODE.) 3. Change or check the input or output port data to determine whether the controlled part is operational and signals are properly input and output. 4. If the controlled part does not operate properly after changing the output port data, select Controller Board Check of I/O Check in the Tech. Rep. mode and determine whether the board is responsible for that malfunction or not. Note Only the output ports given on pages T-37 and 38 may be checked by Controller Board Check of I/O Check in the Tech. Rep. mode.
T-2
<Controlled Part Check Procedure by Changing Input Port Data> Example When a paper misfeed occurs in the paper take-up section of the copier, 1st Drawer Paper Take-Up Sensor PC55 is considered to be responsible for it. Procedure 1. Remove the sheet of paper misfed. 2. From the I/O port check list, it is found that the H/L input signal to PC55 is supplied from PWB-A (IC3A) APB3. 3. Select IC Port Check from the I/O Check function in the Tech. Rep. mode and access the screen which includes the input ports of PWB-A (IC3A) APB3. 4. Check that the input port data of PWB-A (IC3A) APB3 on the screen is H (sensor being unblocked). 5. Move the PC55 actuator to block the sensor. 6. Return to the I/O Check basic screen, select IC Port Check again, choose the screen which includes the APB3 input port data, and make sure that the data has changed from H to L. L: PC55 is operational. H: PC55 is faulty.
T-3
<Controlled Part Check Procedure by Changing Output Port Data> Example When a manual paper misfeed occurs, Manual Feed Paper Take-Up Clutch CL51 is considered to be responsible for it. Procedure 1. Remove the sheet of paper misfed and reset the misfeed. 2. From the I/O port check list, it is found that the ON/OFF output signal of CL51 is supplied from PWB-A (IC5A) BPA1. 3. Select IC Port Check from the I/O Check function in the Tech. Rep. mode and access the screen which includes the output ports of PWB-A (IC5A) BPA1. 4. Check that the output port data of PWB-A (IC5A) BPA1 on the screen is 1 (CL51 is deenergized). 5. Touch the CHANGE key on the screen to change the data from 1 to 0, causing CL51 to be energized for approx. 5 seconds. This allows you to determine whether the Clutch is operational or faulty by checking for the Clutch sound. Operational: Sound produced. Faulty: No sound produced.
6. If CL51 was not energized, make the Controller Board Check in the same mode (for some electrical parts only). 7. If the ON signal of CL51 is not output from PWB-A, the corresponding malfunction code is displayed. For CL51, C033B is displayed.
