02/20002-62 DocuPrint N2025/N2825RAP 67Initial IssueStatus Indicator Repair Analysis ProceduresRAP 67 C5: OCT Tray FullError code indicates that the OCT Output Tray is full.ProcedureEnter Diagnostics and select Component Test. Scroll to Sensor Input test and press Enter.Actuate and deactuate the Stack Full Sensor Actuator. The number on the LCD incrementseach time you press and release the actuator.Y NVisually inspect the Stack Full Sensor Actuator. The actuator moves freely and is ingood condition (not broken or damaged).Y NReplace the Stack Full Actuator (REP 5.3).Switch the printer power off. Remove the Left Side Cover (REP 1.1) and the Print EngineController PWB Cover (REP 8.5). Disconnect P/J19 from the Print Engine ControllerPWB. Switch the printer power on. On the Print Engine Controller PWB, measure the volt-age between P19 pin 11 and frame ground and between P19 pin 13 and frame ground.Both voltages are +3.3VDC.Y NMeasure the voltage between P/J16 pin 4 and frame ground. The voltage is+3.3VDC.Y NReplace the LVPS (REP 8.6).Replace the Print Engine Controller PWB (REP 8.5).Switch the printer power off. Reconnect P/J19 to the Print Engine Controller PWB. EnterDiagnostics and select Component Test. Scroll to Sensor Input test and press Enter. Onthe Print Engine Controller PWB, measure the voltage between P/J19 pin 13 and frameground. There is +3.3VDC between P19 pin 13 and frame ground when the Stack FullSensor is deactuated and 0.0VDC when actuated.Y NSwitch the printer power off. Open the Rear Cover. Disconnect P/J527 (3-pin con-nector on HVPS Cover). Switch the printer power on. Measure the voltage betweenP/J527 pin 3 and frame ground and between P/J527 pin 1 and frame ground. Bothvoltages are +3.3VDC.Y NSwitch the printer power off. Remove the HVPS Cover (REP 8.2). Measure theresistance between P/J502 and P/J527 as follows:• J527-1 and J502-1• J527-2 and J502-2• J527-3 and J502-3There is continuity between each of the pins.Y NRepair or replace the Stack Full Sensor Harness, as necessary (PL 6.1).Disconnect P/J501 from the Duplex Interface PWB and P/J19 from the PrintEngine Controller PWB. Measure the resistance between P/J501 and P/J19 asfollows:• J501-1 and J19-13• J501-2 and J19-12• J501-3 and J19-11There is continuity between each of the pins.Y NRepair or replace the Duplex Interface Harness, as necessary (PL 9.1).Replace the Duplex Interface PWB (REP 8.3).Switch the printer power off. Disconnect P/J507 from the Stack Full Sensor. Checkthe continuity between P/J507 and P/J527 as follows.• J507-1 and J527-3• J507-2 and J527-2• J507-3 and J527-1There is continuity between each of the pins.Y NRepair or replace the Stack Full Sensor(REP 5.2) or Stack Full Sensor Harness(PL 6.1), as necessary.Replace the Stack Full Sensor (REP 5.2).Replace the Print Engine Controller PWB (REP 8.5).It appears that the Stack Full Sensor is working correctly. If a problem persists, replace thePrint Engine Controller PWB (REP 8.5).AABBCC
