Procedure
Check the moving parts of the IIT Carriage for foreign substances and distortion. There are
no foreign substances or distortion of the parts.
Y
N
Remove the foreign substances. If there is distortion in the Capstan Pulley, Capstan Shaft
or Carriage Cable (
PL 1.3
), replace the parts accordingly.
Remove the Xerographic Cartridge (
PL 8.1
) and reinstall. Turn the power Off/On and print.
The problem reoccurs.
Y
N
End
Install a new Xerographic Cartridge (
PL 8.1
). Turn the power Off/On and print. The problem
reoccurs.
Y

End
Remove the HVPS and reinstall. Turn the power Off/On and print. The problem reoccurs.
Y

End
Check the connections of
P500
at the HVPS and
P/J403
on the MCU PWB. The connec-
tors are connected correctly.
Y
N
Connect the connectors.
Check the wires between
P500
at the HVPS and
P/J403
on the MCU PWB for an open circuit
or a short circuit. The wires are conducting without an open circuit or a short circuit.
Y
N
Repair the open circuit or short circuit.
Check the wires between
P/J160
and
P/J170
on the ROS, and
P/J405
on the MCU PWB;
and between
P/J401
on the MCU PWB and
P/J328
on the ESS PWB for an open circuit or a
short circuit. The wires are conducting without an open circuit or a short circuit.
Y
N
Repair the open circuit or short circuit.
Replace the HVPS (
PL 18.1
). If the problem reoccurs, replace the ROS (
PL 2.1
). If the problem
reoccurs, replace the MCU PWB (
PL 18.2
). If the problem reoccurs, replace the ESS PWB (
PL
35.2
).

Procedure
Check the installation of the ROS (
REP 6.2
). The ROS is installed correctly.
Y
N
Install the ROS correctly (
REP 6.2
).
Check the drum ground contact point for dirt and distortion. The drum ground contact point
is clean and there is no distortion.
Y
N
Clean the drum ground contact point and correct the distortion.
Remove the Xerographic Cartridge (
PL 8.1
) and reinstall. Turn the power Off/On and print.
The problem reoccurs.

Set to print a black copy. During the print cycle, turn off the power after the feeding sound is
heard (i.e. terminate processing midway through copying). Check the surface of the drum.
There is a considerable amount of toner left on the surface of the drum.
Y
N
Check the connections of
P/J140
at the ROS and
P/J404
on the MCU PWB. The con-
nectors are connected correctly.
Y
N
Connect the connectors.
Check the installation of the ROS (
REP 6.2
). The ROS is installed correctly.
Y
N
Install the ROS correctly (
REP 6.2
).
Measure the voltage at
P/J404
Pin 2 on the MCU PWB. The voltage is approx. +5VDC.
Y
N
Replace the MCU PWB (
PL 18.2
).
Check the wires between
P/J140
at the ROS and
P/J404
on the MCU PWB for an open
circuit or a short circuit. The wire are conducting without an open circuit or a short
circuit.
Y
N
Repair the open circuit or short circuit.
Replace the ROS Unit (
PL 2.1
). If the problem persists, replace the MCU PWB (
PL 18.2
).
