Troubleshooting Procedure
Step Actions and Questions Yes No
1 Does the error occur when the power is
turned Off and On?
Go to step 2. Complete.
2 Reseat the Imaging Unit.
Does the error still occur when the
power is turned Off and On?
Go to step 3. Complete.
3 Check the Main Motor for rotation.
In the Printer Diagnostic tests, use
Engine Diag > Motor Test > Main
Motor FULL1.
Does the Main Motor function
normally?
Replace the
MCU Board.

Go to step 4.
4 Check the connections between the
MCU Board and Main Drive Assy.
Are P/J21 and P/J211 connected
correctly?
Go to step 6. Reconnect the
connector(s) P/
J21 and/or P/
J211 correctly,
then go to step
5.
5 Does the error still occur when the
power is turned Off and On?
Go to step 6. Complete.
6 Reseat the Main Drive Assy.
Does the error still occur when the
power is turned Off and On?
Go to step 7. Complete.
7 Disconnect J21 from the MCU Board.
Measure the voltages across J21-2/
J21-4 <=> ground on the MCU Board.
Are the voltages about +24 VDC when
the interlock switch (Interlock Harness
Assy) is pushed?
Replace the
Main Drive
Assy.
