10. COPY QUALITY ADJUSTMENT
10.1 LIGHT INTENSITY ADJUSTMENT (SP4-001)
When:
When replacing the drum - After performing SP3-123
(Drum initialization) and before exiting SP mode.
Purpose:
To maintain the correct light intensity.
Adjustment standard:
Level 2 of the gray scale on the OS-A3 test chart
should be just visible on the copy when the 4th
manual image density level is selected.
How:
SP4-001 changes the exposure lamp voltage from
the ac drive circuit on the dc power supply board.
NOTE: When replacing the drum, light intensity adjustment should be done only
after performing SP3-123.
If the light intensity is adjusted, ADS gain data and V
L
correction data are
cleared. Therefore, after the light intensity adjustment, auto ADS gain
adjustment (SP4-201) and forced V
L
detection (SP3-105) must be
performed.
See "Practical SP Mode Use Tables" in section 4 for the exact order in
which SP modes must be done after changing major components.
1. Turn the main switch off.
2. Clean the following parts:
Item No.
