Troubleshooting Procedure
Steps Actions and Questions Yes No
1 Check the duplex unit switch:
1.Remove the duplex unit switch.
2.Test for continuity across J520-2 <=>
J520-1 while pushing and releasing the
duplex switch.
Is the switch continuous when pushed,
and open when released?
Go to step 2. Replace the
duplex unit
switch
(page 8-110).
2 Check the duplex unit Cover harness:
1.Remove the duplex unit Cover harness.
2.Test J52 <=> J520 for continuity.
Is the harness continuous?
Go to step 3. Replace the
duplex unit
cover
assembly
harness.
3 Check the duplex unit harness:
1.Remove the duplex unit harness.
2.Test J50 <=> J2750 for continuity.
Is the harness continuous?
Go to step 4. Replace the
duplex unit
assembly
harness.
4 Check the LVPS harness assembly:
1.Remove the LVPS harness assembly.
2.Test J27 <=> J2750 for continuity.
Is the harness continuous?
Go to step 5. Replace the
LVPS harness
assembly.
5 Check the 3.3 V line to the duplex unit:
1.Remove the print cartridge.
2.Measure the voltage across P/J27-4 <=>
P/J27-3 on the HVPS/engine logic board.
Does the voltage measure 3.3 VDC?
Go to “Duplex
Unit PWBA”
on page 4-49.
Go to step 6.
