When the mirror motor is replaced.
Change the mirror base scan speed to adjust the lateral magnification ratio.
1 Set a scale on the original table as shown in the figure and
perform Simulation 48-02.
The machine starts the warm-up cycle and the ready lamp is lit.
At the same time a preset value (ranging from 15 to 35) is
indicated.
Now take a full-size copy of the scale and determine the correction factor for lateral magnification according to the following
expression:
Correction factor for lateral magnification = [(original size – copy
size)/original size] x 100 (%)
2 Use the correction factor to change the indicated value:
Value to be input = (preset value) + (correction factor for lateral
magnification(%)) x 10
• Eg.1: 35 = 25 + 1 x 10
• Eg.2: 15 = 25 + (–1 x 10)
When a new value is typed and the print switch is pressed, the
new value is stored in memory and the ready lamp goes off.
3 Clear Simulation 48-02.
Note: In Simulation 48-02 the correctable range of the
preset value is limited from15 to 35.

2 Input a new preset value.
Eg.: When a value shown on lens is +1.2, a correction value to
be input is 14 according to the table.
<Inputting the lens characteristics>
The lens varies in focal length for each machine. The lens travel is
required to correspond to the focal length of the lens. If the lens
travels at a magnification would be constant among the machines
in spite of the focal length irregularity, the magnification could vary
depending on this irregularity.
To avoid this problem, we have prepared the table showing focal
length ranks of lens and correction data (see the next page) which
can be stored in memory at the time of Simulations described
below. In order to copy properly at a magnification, the lens travel
corresponding to its focal length is calculated on the basis of the
stored data.

If the width of the front end solid (La) is equal to that of the rear end

Otherwise, follow the steps 4 to 7 described below:
4 Loosen screws securing the mirror base driving pulley on the
rear frame side.
If La is bigger than Lb, rotate the mirror base driving pulley on
the rear frame side in the A direction. (Do not rotate the flange
and the shaft of the mirror base driving pulley).
If La is smaller than Lb, rotate the mirror base driving pulley on
the rear frame side in the B direction. (Do not rotate the flange
and the shaft of the mirror base driving pulley).
5 Tighten the screws securing the mirror base driving pulley.
6 Repeat steps 1 to 3.
7 If La is not equal to Lb, repeat steps 4 and 5 until La=Lb.

(8) Correcting the Lateral Distortion
If the lateral distortion occurs without the longitudinal distortion(distortion in the mirror base scanning direction), the lateral distortion
can be corrected by adjusting the height of 2. and 3. mirror base
and/or the eccentric roller of 4. and 5. mirror base.
The correction procedure is as follows:
Original
Copy
1 Preparing the reference original:
On an A3-size or 11" x 17" blank paper, draw 2 parallel lines at
the positions 10 mm away from the both ends.

at 4 positions (La, Lb, Lc and Ld).
La

7 – 13
If La=Lb and Lc=Ld, no adjustment is required.
If La>Lb(Lc<Ld), rotate the eccentric roller in one direction to raise
the front frame side of the 4. and 5. mirror base unit.
If La<Lb(Lc>Ld), rotate the eccentric roller in the other direction to
lower the front frame side of the 4. and 5. mirror base unit.
Note: Remember how much the roller is rotated.
(One rotation of the roller causes the height of the front frame side
to change by 2 mm and the difference between La and Lb to
change by 4 mm).
* After opening the front cabinet, the adjustment described above
can be made through the access hole.
If the above procedure does not provide sufficient adjustment, follow the steps shown below:
1 Move the B rail of the mirror base upward or downward (in the
arrow direction).
If La>Lb, raise the mirror base B rail on the paper discharge side
by one-half of (La-Lb).
If La<Lb, lower the mirror base B rail on the paper discharge
side by one-half of (Lb-La).
ex.:
When La=12 mm and Lb=9 mm, raise the mirror base B rail on
the paper discharge side by 1.5 mm.
If Lc>Ld, lower the mirror base B rail on the paper discharge
side by one-half of (Lc-Ld).
If Lc<Ld, raise the mirror base B rail on the paper discharge side
by one-half of (Ld-Lc).
(Grasping the grip of the mirror base rail, move the mirror base
rail).
2 Adjust the eccentric roller as described in 1) until La=Lb and
Lc=Ld.
3 After adjustment, manually rotate the mirror base driving pulley
to check that the mirror base A and B do not come into contact
with each other during full-scanning motion.
Note: If the mirror base rail is moved excessively, the mirror bases may contact with each other.
(9) Adjusting the Center Deviation
Take a full-size copy and compare the copy with the original.
If the deviation of the copy center from the original center is more
than 2mm, move the lens in the arrow direction so that the deviation
is 2 mm or less.
Note: After moving the lens, adjust the position of the blank
lamp because a change of the reference center position
results in a change of the blank lamp position.

lamp, reflector).
2 Clean the automatic exposure sensor (clean the surface of the
photosensor with a soft cloth soaked with alcohol or water).
(Note: The use of dry cloth will cause dust adhesion on the surface of the sensor due to static electricity).
3 Clean the (transfer and separation) charger wire and the screen
grid.
4 Clean the blank lamp and the separation lamp around the drum
holder unit.
5 Clean the drum cleaning blade. (After cleaning, always apply powder on the blade).

This is the test command used to test the optical system. The mirror base automatically starts to scan.
(1) With depression of the PAUSE key, the control moves from the test command mode to be ready to
execute it. The READY pilot lamp (RPL) comes active with the zoom ratio at 100%. It is possible to
change the zoom mode using the ZOOM key.
(2) When the PRINT key is pressed while the RPL is active, the status lamp turns off and the test
command starts to execute. The mirror base moves to scan in the zoom ratio at that time.
(3) If the door is opened while the operation is in process, the operation is interrupted with status "CH"
prompted. Closing the door will start the operation all over again from its initial step.

Lens characteristics entry (at a time of lens replacement)
Because each lens has a variance in focal distance, the lens moving distance in any zoom mode must
correspond with the focal distance of the lens. The zoom ratio varies proportionate to the variance of
the lens focal distance.
To avoid focus problem, the class of the lens focal distance (refer to chart on page 7-11) is stored in the
memory using the test command. In a variable zoom mode, the lens moving distance that corresponds
to the lens focal distance is obtained on the basis of the data so as to produce the accurate zoom copy.

Front/rear direction zoom ratio adjustment (refer to [7]-3-(6)-9 for the lens type value.
Used to set the No.4/5 mirror home position (focal adjustment) and to adjust the zoom ratio of the copy
in the vertical direction (from front to rear).
There are two kinds of test command 48-01 of which are described as follows.
1-1.
Horizontal copy zoom ratio standard value input method (at a time of lens or main PWB
replacement)
Press the C → =↵ → 0 → =↵ → 4 → 8 → PSW → ➡ keys. The already
set value or "40" is displayed.
Substitute the value of "O.L" shown on the label attached to the lens with the formula value.
40 – [(value of O.L.) x 5] = standard value of correction
Ex: 40 – (+1.2 x 5) = 34
1-2.
Use this test command to adjust the horizontal zoom ratio. Change the value entered in "1-1" to
change.
2-1.
No.4/4 mirror home position standard value input (at a time of lens or main PWB replacement).
[7]-8-(1)
[8]-3-(3)
Press the C → =↵ → 0 → =↵ → 4 → 8 → PSW 1 → PSW keys. The already stored value or "42" is displayed.
Substitute the value of "O.L" shown on the label attached to the lens with the formula value.
[7]-8-(2)
[7]-9-(4)
42 – [(O.L value) x 10] = standard value of correction
Ex: 42 – (+1.2 x 10) = 30
2-2.
To adjust the resolution, change the value entered at "2-1" using this test command.
When the No. 4/5 mirror reference value is "+" from the center value "50", the mirror is shifted
away from the lens to lengthen the light path. When it is "–", the mirror is shifted to the lens to
shorten the light path. The value is calculated in this manner.
