type) When this simulation is executed, the machine starts warming
up and the LCD shows the following display. The currently set
value of "50_L1" (Lead edge shift at 200% copy) is displayed
on the copy quantity display. — — P. 8 – 17
SIMULATION NO. 50-2
INPUT_A (0~999)
Enter the value of "lead edge shift at 200% copy" with the
10-key pad and press the PROGRAM ( P ) key to store it.
Press the scroll key (
→
) to scroll the message display on the
LCD and the copy quantity display as follows:
50_L2

The set value can be stored or changed in the same manner
as in "50A."
After completion of warming up, copying is allowed.
Note 1: ( ) shows the input range of adjustment value.
Note 2: When "50_L1" is entered, the copy magnification ratio
is automatically set to 200%.
[Adjustment procedure]
1. Set L1 and L2 to "0."
2. Put a scale on the original table.
3. Make a copy at 200%.
4. Make a copy at 100%.
5. Set the screen to "INPUT_L1" display, and enter the lead
edge shift at 200% copy with the 10-key pad.
(Example) IN the case of 35.5mm, enter "355."
6. Set the screen to "INPUT_L2" display, and enter the lead
