ADC TUNE UP
This mode should be used to improve the problem when there is insufficient separation of
paper from the transfer drum (when the winding jam occurred around the drum). Using the
mode, you can adjust the bias voltage of paper discharging output from the high-voltage
power supply unit. Adjustment is to adjust the drum cleaner bias voltage against the
reference value 0 (zero) in the range -4 and +4.
NOTE:
Do not perform this mode frequently.
