44 01 Correction mode setting
[+ 1] Process control correction enable
[+ 2] Optical dirt correction enable
[+ 4] Drum layer wear correction enable
[+10] Toner control A correction valid
[+20] Toner control B correction valid
Note: When all are "Enable," set to 37.
The corrections, except for the process control correction mode, can be disabled in the normal
copy mode. When "0" is inputted, "1" (Process control correction) is enabled. (Automatic setting)
02 Drum mark sensor sensitivity adjustment : 0 ~ 255 255=5V
For the drum mark sensor gain rank, [2] is selected.
The main motor rotates and the drum mark sensor sensing level is displayed on the multi-display
section. Adjust VR1 in the process unit to obtain [204
±
10].
03 Image density sensor sensitivity adjustment : 0 ~ 255 255=5V
For the image density sensor gain rank, [2] is selected.
The main motor rotates and the image density sensor sensing level is displayed on the multi-display
section. Adjust VR2 in the process unit to obtain [204
±
10].
05 Test mode
The main motor rotates to form images in nine steps of the grid bias level from 350V to 590V (30V step)
on the drum, and the image density sensor level is displayed on the LCD.
