Drum Unit Life Detection
Life of the Drum Unit (Photosensitive Drum) is detected.
This machine does not have a Photosensitive Drum film thickness detection mechanism
so the change in the film thickness is calculated by the rotation time of the Photosensitive
Drum + time that the primary charging DC bias is applied.
Detection timing
• At power-on
•
At every print
•
At recovery from sleep mode
Detection description
1) The count value for the drum life is calculated by the rotation time of the Photosensitive
Drum + time that the primary charging DC bias is applied as well as the time that the
developing AC bias is applied.
2) The count value calculated in step 1 of "Control description" is added to the drum
count value stored in the Drum Unit Memory PCB of the Drum Unit.
NOTE:
The life (displayed in %) can be checked by the following service mode:
• Drum counter life display (Y)
COPIER > COUNTER > LF > Y-DRM-LF
• Drum counter life display (M)
COPIER > COUNTER > LF > M-DRM-LF
• Drum counter life display (C)
COPIER > COUNTER > LF > C-DRM-LF
• Drum counter life display (Bk)
COPIER > COUNTER > LF > K-DRM-LF
