■ Discharge Current Control
This machine performs sampling for the time corresponding to a single drum rotation for each voltage to control the discharge
current because of the following reasons.
Discharge current control outputs Vpp to an area uncharged by AC bias and an area charged by AC bias, and performs sampling
of the current to calculate the optimal discharge current.
The amount of discharge from the Charging Roller that is based on temperature characteristics is significantly affected by
environmental changes. Therefore, the discharge amount needs to be corrected in accordance with the changes.

■ Drum Unit Detection
Whether the Drum Unit is installed or not is detected.
Detection timing:
• At power-on
• When recovering from sleep (after 8 hours or more have elapsed)
Detection description:
The following is determined from the AC current monitor value when discharge current control is executed to detect the
presence or absence of the Drum Unit.
• When the current monitor value is less than the specified value: Drum Unit absent
• When the current monitor value is the specified value or higher: Drum Unit present
NOTE:
If the Drum Unit is detected as present but the memory of the Drum Unit is not detected, alarm code 09-0010/0011/0012/0013 is
generated.
Operation of the host machine:
If the Drum Unit is detected as absent, "Insert the drum unit. (XXXX)" is displayed on the status line of the Control Panel.
(XXXX is the color name.)
