Code Y101700-5
CAUTION
This product is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH standard and IEC825. This
means that this machine does not produce hazardous laser radiation. The use of controls, adjustments or performance of
procedures other than those specified herein may result in hazardous radiation exposure.
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eyes retina, there
is the danger of spot damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not as individual
parts.
2) Do not look into the machine with the main switch turned on after removing the developer unit, toner cartridge, and drum
cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and
installing the optical system.
4) The middle frame contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

INSTALLATION
2.1 Copier installation
Improper installation may damage the copier. Please
note the following during initial installation and whenever
the copier is moved.
Caution: If the copier is moved from a cool place to a
warm place, condensation may form inside the
copier. Operation in this condition will cause
poor copy quality and malfunctions. Leave the
copier at room temperature for at least 2 hours
before use.

The scanner unit performs scanning in the digital optical system. The light from the light source (Xenon lamp) is reflected by
a document and passed through three mirrors and reduction lenses to the CCD element (image sensor) where images are
formed. This system is known as the reduction image sensor system. Photo energy on the CCD element is converted into
electrical signals (analog signals). (Photo-electric conversion). The output signals (analog signals) are converted into digital
signals (A/D conversion) and passed to the MCU (main control/image process section). The resolution at that time is 400dpi.
The mirror unit in the scanner section is driven by the mirror motor. The MHPS is provided to detect the home position of the copy
lamp unit.

5) At this time, the paper is fed past the paper entry detection
switch (PPD1), and detected by it. After about 0.15 sec
from detection of paper by PPD1, the tray paper feed
solenoid (PFS) turns on so that the clutch sleeve projection
comes into contact with the paper feed latch to stop the
pick-up roller. Then the pick-up roller rotates for about
0.15 sec so that the lead edge of the paper is evenly
pressed on the resist roller, preventing against skew
feeding.
3) After about 0.1 sec from when the main motor starts
rotating, the tray paper feed solenoid (PFS) turns on
momentarily.
This disengages the paper feed latch from the projection
of the clutch sleeve, transmitting rotation of the pick-up
drive gear to the paper feed roller shaft, rotating the pickup roller to feed the paper.

2) Execute SIM 50 01
3) Set the print start position (AE lamp ON) (A), the lead
edge void amount (TEXT lamp ON) (B), and the scan
start position (PHOTO lamp ON) (C) to 0, and make a
copy of a scale at 100%.
4) Measure the image loss amount (R mm) of the scale
image. Set C = 10 x R (mm). (Example: Set the value of
C to 30.) When the value of C is increased by 10, the
image loss is decreased by 1mm. (Default: 50)
5) Measure the distance (H mm) between the paper lead
edge and the image print start position. Set A = 10 x H
(mm). (Example: Set the value of A to 50.)
When the value of A is increased by 10, the image lead
edge is shifted to the paper lead edge by 1mm.
(Default: 50)
6) Set the lead edge void amount to B = 50 (2.5mm).
When the value of B is increased by 10, the void amount
is increased by about 1mm. For 25 or less, however, the
void amount becomes zero. (Default: 50)

The value displayed after execution of this simulation can be set in the range of 0 99
with 50 as the center value.
When the text mode set value is Gat3, for example, the GAMMA ADJUST register value
set at Exp1 is:
Text Exp1 = Gat3 50 24
When 40 is set to Gat3, Text Exp1 = 40 50 24 = 34
Then set the GAMMA ADJUST register set value to 34.
Perform the same procedure for each mode and each Exp.
* The above table may subject to change.
* For the gradient, there is a similar table, though not specified here. The value set with
SIM 46, however, is not reflected.
* The AE mode Exp selection is not specified, but corresponds to the grades for AE
exposure selection in the former models.

Lead edge image position adjustment + Paper lead edge/rear edge void adjustment
(Outline)
This adjustment is used to adjust the copy image position and lead edge/rear edge void
amount on the copy paper by adjusting the image scan start position and the print start
position (resist roller ON timing) at 100%.
(Operation/Procedure)
1. When this simulation is executed, the currently set value is displayed in two digits.
(Center value: 50)
2. When the copy mode select key is pressed, each setting mode and the display are
changed.
* The selected adjustment mode is indicated by the lamps as shown in the table
below.
3. Enter the adjustment value with the 10-key and press the start key. The set value is
stored and a copy is made. (When the set value is increased by 1, the void amount is
shifted by 0.1 mm.)
4. When the clear key is pressed, the set value is stored and the simulation mode is
terminated.

(Adjustment method)
1. Set the print start position (A: AE ON), the lead edge void amount (B: TEXT ON), the
scanning start position (C: PHOTO ON) to zero and make a copy of a scale at 100%.
2. Measure the image loss R (mm) of the scale.
Set as C = 10 R (mm).
(Example: Set to 30.)
* When C is increased by 10, the image loss
is decreased by 1 mm. (Default: 5)
3. Measure the distance H (mm) from the paper
lead edge to the image print start position.
Set as A = 10 R (mm). (Example: Set to 50.)
* When the value of A is increased by 10, the
image lead edge is shifted toward the paper
lead edge by 1 mm. (Default: 50)
4. Set the lead edge void amount as
B = 50 (2.5 mm). (Default: 50)
* When the value of B is increased by 10,
the void is increased by about 1 mm.
(For 25 or less, however, the void amount becomes zero.)

Shading check
(Outline)
Used to display the detection level of the white plate for shading. (Vref of AD conversion
IC is fixed.)
(Operation/Procedure)
When the START key is pressed, the mirror base unit moves to the white plate for
shading and Vref+ voltage of AD conversion IC is set to 4.5V and Vref- voltage to 0.5V,
and the copy lamp is lighted.
This state is kept for 10 sec, and the level of one pixel at the center is detected every
second to display on the value display section.

Self print only with the engine (1 by 2 mode)
(Outline)
Used to print in the 1 by 2 mode by ignoring the state of the optical system.
(Operation/Procedure)
1. When this simulation is executed, warming up is made and the ready lamp is lighted.
2. Select with the cassette select key and press the start key. Paper is fed from the
cassette and printing is performed.
In the 1 by 2 mode, one line is printed and two lines are not printed.
