(7) OPC drum marking sensor/Image density sensor
gain adjustment
This adjustment must be performed in the following cases:
·
When both sensors are cleaned in maintenance.
·
When the value of DMLED/PCLED in SIM 44-12 are greater than
about 100.
Clean both sensors and perform the adjustment.
1) Execute SIM 44-2.
