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. Switchthe main power on. Measure the voltage between P/J19-11 and frame ground. The voltage is3.2VDC.Y NCheck the voltage between P/J16 pin 4 and frame ground. The voltage is 3.2VDC.Y NReplace the LVPS (REP 8.6).Replace the Print Engine Controller PWB (REP 8.5).Switch the Main Power off. Remove the OCT Front Cover (REP 10.4). Disconnect P/J514 fromthe OCT PWB. Check for continuity between the following pins:• P514-2 and P19-2• P514-3 and P19-3• P514-4 and P19-4• P514-6 and P19-11• P514-7 and P19-12There is continuity between all pins measured.Y NRepair or replace the OCT Harness (PL 10.2) or the Duplex interface Harness (PL 9.2).Replace the OCT PWB (REP 10.14).RAP 72 Offset Operation Not PerformedProcedureManually move the Offset Assembly from one side to the other. The Offset Assembly movessmoothly.Y NReplace the Offset Assembly (PL 10.2).Enter Diagnostics and select Component Test. Scroll to OCT Offset Motor and press Enter [4].The Offset Assembly shifts left then returns right.Y NSwitch the printer power off. Remove the OCT Front Cover (REP 10.4). Disconnect P/J515 from the OCT PWB. Measure the resistance between pins 1 and 2 of the discon-nected plug. The resistance is approximately 90 ohms.Y NReplace the OCT Offset Motor (REP 10.9).Remove the Left Side Cover (REP 1.1) and the Print Engine Controller PWB Cover (REP8.5). Disconnect P/J19 from the Print Engine Controller PWB. Disconnect P/J514 fromthe OCT PWB. Check for continuity between the following pins:• P514-2 and P19-2• P514-3 and P19-3• P514-4 and P19-4• P514-6 and P19-11• P514-7 and P19-12There is continuity between all pins measured.Y NRepair or replace the OCT Harness (PL 10.2) or the Duplex interface Harness (PL9.2).Replace the OCT PWB (REP 10.14).Replace the Print Engine Controller PWB (REP 8.5).
