value of "50_L1" (Lead edge shift at 200% copy) is displayed
on the copy quantity display.
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 → 50C → 50D → 50E → 50_L1 → 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.
