Measure the voltage on the LVPS between P/J281 pin 12 and frame groundas you switch the printer power on. The voltage is 0.0VDC during fuser warm up, thenchanges to 2.8VDC.Y NReplace the Print Engine Controller PWB (REP 9.3).Replace the LVPS (REP 9.5).RAP 32 Registration SensorProcedureEnter Diagnostics and select Component Test. Scroll to Sensor Input test and press Enter.Actuate and deactuate the Registration Sensor. The number on the LCD increments eachtime you press and release the actuator.Y NThe actuator moves freely and is in good condition (not broken or damaged).Y NReplace the Registration Actuator (REP 4.2).Switch the printer power off. Remove the Left Interface Cover (REP 1.1), Left Cover (REP1.2), and the Left Plate Assembly (REP 1.11). Switch the printer power on. On the PrintEngine Controller PWB, measure the voltage between P/J23 pin 11 and frame ground.The voltage is +3.3VDC with the Registration Sensor deactuated and 0.0VDC withthe Registration Sensor actuated.Y NSwitch the printer power off. Remove the Left Front Cover (REP 1.7). Switch theprinter power on. On the Connector PWB, measure the voltage between P/J43 pin 5and frame ground. The voltage is +3.3VDC with the Registration Sensor deactu-ated and 0.0VDC with the Registration Sensor actuated.Y NCheck the voltage between P/J43 pin 3 and frame ground. The voltage is1.2VDC.Y NReplace the Print Engine Controller PWB (REP 9.3).Replace the Registration Sensor (REP 5.4).Replace the Connector PWB (REP 9.7).Replace the Print Engine Controller PWB (REP 9.3).It appears that the Registration Sensor is working correctly. If a problem persists, replace thePrint Engine Controller PWB (REP 9.3).Amanuals4you.commanuals4you.com
