Reseat the feeders and printer to obtain proper alignment and connection.
Switch the printer power off. Remove the Left Side Cover (REP 1.1) and the Print Engine Con-
troller PWB Cover (REP 8.5). Disconnect P/J13 from the Print Engine Controller PWB. Switch
the printer power on. Check the voltage between P13 pin 10 on the Print Engine Controller
PWB and frame ground. The voltage is 1.0VDC.
Y N
Replace the Print Engine Controller PWB (REP 8.5).
The printer contains only one 500 Sheet Feeder.

Switch the printer power off. Remove the Left Side Cover (REP 11.3) from the top 500
Sheet Feeder. Disconnect P/J136 from the Feeder PWB. Reconnect P/J13 to the Print
Engine Controller PWB. Switch the printer power on. Check the voltage between P13 pin
10 on the Print Engine Controller PWB and frame ground. The voltage is 1.9VDC.
Y N
Switch the printer power off. Disconnect P/J13 from the Print Engine Controller PWB
and P/J132 from the Feeder PWB. Check for the continuity between each of the Pins
on P13 and P132 as follows:
• P13-1 and P132-1
• P13-2 and P132-2
• P13-3 and P132-3
• P13-4 and P132-4

• P13-13 and P132-12
• P13-14 and P132-13
• P13-15 and P132-14
There is continuity between all pins measured.
Y N
Repair or replace the harness between P/J13 and P/J131 (PL 9.1) or between
