RAP 60 Duplex Fail

Procedure
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/J19 from the Print Engine Controller PWB. Switch
the main power on. Measure the voltage between P19 pin 4 on the Print Engine Controller
PWB and frame ground. The voltage is 3.3VDC.
Y N
Replace the Print Engine Controller PWB (REP 8.5).
Switch the Main Power off. Reconnect P/J19 to the Print Engine Controller PWB. Remove the
OCT, if installed. Switch the main power on. Measure the voltage between P/J19 pin 4 and
frame ground. The voltage is 1.6VDC.
Y N
Switch the printer power off. Open the Rear Cover and remove the Duplex Assembly
(REP 9.1). Remove the HVPS Cover (REP 8.2). Disconnect P/J501 from the Duplex Inter-
face PWB and P/J19 from the Print Engine Controller PWB. Check for the continuity
between the following pins:
• J501-1 and J19-13
• J501-2 and J19-12
• J501-3 and J19-11
• J501-4 and J19-10
• J501-5 and J19-9
• J501-6 and J19-8
• J501-7 and J19-7
• J501-8 and J19-6
• J501-9 and J19-5
• J501-10 and J19-4
• J501-11 and J19-3
• J501-12 and J19-2
• J501-13 and J19-1
There is continuity on all pins measured.
Y N
Replace the Duplex Interface PWB Harness (PL 9.1).
Replace the Duplex PWB (REP 9.7). If the problem persists, replace the Duplex Interface
PWB (REP 8.3).
Replace the Print Engine Controller PWB (REP 8.5).
