Procedure
Check the moving parts of the IIT Carriage for foreign substances and distortion. There
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

Y N
End
Remove the HVPS and reinstall. Turn the power Off/On and print. The problem reoccurs.
Y N
End
Check the connections of P500 at the HVPS and
tors are connected correctly.
Y N
Connect the connectors.
Check the wires between P500 at the HVPS and
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
and between P/J401 on the MCU PWB and
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
