The error code reappears.Y NProblem solved.Open the OCT Rear Cover and check the Rear Cover Interlock Switch. The Rear Cover Inter-lock Switch is in good condition and the actuator moves freely.Y NReplace the OCT Rear Cover Interlock Switch (REP 10.13).Enter Diagnostics and select Component Test. Scroll to Sensor Input test and press Enter [4].Actuate and deactuate the Rear Cover Interlock Switch. The number on the LCD incrementseach time you press and release the actuator.Y NSwitch the printer power off. Remove the OCT Front Cover (REP 10.4). Disconnect P/J524 from the OCT PWB. Switch the printer power on. Measure the voltage betweenP524 pin 1 and frame ground. The voltage is 3.2VDC.Y NMeasure the voltage between P/J514 pin 6 and frame ground. The voltage is3.2VDC.Y NSwitch the printer power off. Remove the Left Side Cover (REP 1.1) and thePrint Engine Controller PWB Cover (REP 8.5). Measure the voltage between P/J19 pin 11 and frame ground. The voltage is 3.2VDC.Y NReplace the Print Engine Controller PWB (REP 8.5).Check for continuity between P/J19 pin 11 and P/J501 pin 3 and between P/J504 pin 6 and P/J514 pin 6. There is continuity between both sets of pins.Y NRepair or replace the OCT Harness (PL 10.2) or the Duplex interface Har-ness (PL 9.2).Replace the Duplex Interface PWB (REP 8.3).Replace the OCT PWB (REP 10.14).Switch the printer power off. Reconnect P/J524 to the OCT PWB. Switch the printer poweron. Measure the voltage between P524 pin 1 and frame ground as you actuate and deac-tuate the interlock switch. The voltage is 3.2VDC when the switch is deactuated and0.0VDC when the switch is actuated.Y NReplace the OCT Rear Cover Interlock Switch (REP 10.13).Replace the Print Engine Controller PWB (REP 8.5).Replace the Print Engine Controller PWB (REP 8.5).RAP 70 OCT Motor AssemblyProcedureSwitch the printer power off. Remove the HVPS Cover (REP 1.6). On the Duplex InterfacePWB, disconnect P/J506 and measure the voltage between J506 pin 1 and frame ground.There is 24VDC between J506 pin 1 and frame ground.Y NReplace the LVPS (REP 8.6).Switch the printer Power off. Reconnect P/J506. Remove the OCT Front Cover (REP 10.4).Disconnect P/J514 on the OCT PWB. Measure the voltage between J514 pin 8 and frameground. There is 24VDC between J514 pin 8 and frame ground.Y NSwitch the printer power off. Measure the resistance between P/J504 and P/J514 as fol-lows:• J504 - 1 and J514 - 1• J504 - 2 and J514 - 2• J504 - 3 and J514 - 3• J504 - 4 and J514 - 4• J504 - 5 No Connection• J504 - 6 and J514 - 6• J504 - 7 and J514 - 7• J504 - 8 and J514 - 8• J504 - 9 and J514 - 9There is continuity between each of the pins.Y NRepair or replace the STK-O-Harness Assembly (PL 10.2) and the SK-1 HarnessAssembly (PL 9.1).Replace the Duplex Interface Harness PWB (REP 8.3).Switch printer power off. Reconnect P/J515. On the OCT PWB, measure the voltage betweenP/J517 pin 3 and frame ground and P/J517 pin 4 and frame ground. Both voltages are24VDC.Y NReplace the OCT PWB (PL 10.2).Replace the OCT Motor Assembly (PL 10.2).
