Do the pins 3, 4 and 5 of the connector
P6 on the main PCB have the following value
respectively when a sheet of paper is fed from
the MP tray?
P6-3 pin (DBAC) --- Change in voltage from
6V approx. to 0V just when a sheet of paper is
fed from the registration unit.
P6-4 pin (DBDC) --- Change in voltage from
9V approx. to 0V just when a sheet of paper is
fed from the registration unit.
P6-5 pin (DNSTY) --- Change in voltage to
2.5V just when a sheet of paper is fed.
Replace the scanner unit or
the harness.
Possible cause

Remedy
Dirt on power
supply terminal
Failure in the
development
high-voltage
circuit
Is there any dirt on the cartridge side
development terminal of the transfer unit and
on the terminal of the high-voltage power
supply development unit? (is there continuity
between them?)
11
No
Clean the contacts to assure
the continuity.
Yes
Replace the high-voltage
power supply PCB assy.

Yes
Density setting
Does printed image improve when density
setting is changed on the control panel?
Adjust the proper setting on
the control panel.
