E. Horizontal copy magnification ratio adjustment
a. This adjustment is performed to meet the displayed magnifica-
tion ratio with the actual one.
b. This adjustment must be performed in the following cases:
•
When the main PWB is replaced.
•
When the EEPROM in the main PWB is replaced.
•
When the mirror motor is replaced.
•
When self diag. U2 occurs.
The scanning speed of the mirror base is changed to adjust the
horizontal (paper transport direction) copy magnification ratio.
<Adjustment procedure>
(1) Put a scale on the original table as shown in the figure below,
and execute simulation 48-02. The machine starts warming up
and the ready lamp lights up. At the same time, the previously
set value ( 1 ∼ 99) is displayed. Under this state, make a nor-
mal copy and calculate the copy magnification ratio.

(2) Replace the displayed value with the copy magnification ratio
correction rate obtained in (1).
(Input value) = (Previously set value) / (Copy magnification
ratio correction rate [%]) ×10
(Example) When the previously set value is 25, the input val-
ues of examples 1 and 2 are as follows:
Example 1: 35 = 25 + (1 × 10)
•
Example 2: 15 = 25 + (–1 × 10)
•
Enter the input value and press the print switch. The value
is stored and the ready lamp lights up.

Note: Input correction can be made in the range of 1 – 99
(simulation set range).
