If incorrect, replace the lamp. If correct, replace the fuser top cover assembly. 3 LVPS LVPS to fuser AC cable CAUTION: When taking measurements for AC power, observe all safety precautions. Measure the AC line voltage between the two connectors on the fuser end of the LVPS to fuser AC cable. If the voltage is incorrect, turn the power off, and remove the LVPS. Measure the AC line voltage between pins CN1-1 and CN1-3 on the board. If correct, check the continuity of the LVPS to fuser AC cable. If incorrect, replace the cable. If the AC line voltage at CN1 is incorrect, check fuse F2. If the fuse is blown, replace the fuse. If the fuse is not blown, replace the LVPS assembly.

Error code:	928
Display:	Power Off/on 928: Error
Description:	Failure in the Fuser Motor The Fuser Motor has stopped rotating. Applicable Status Code: Code 928: The Fuser Motor has failed.
Causes:	• Fuser Motor, PL2.1.9 • Motor Driver Board, PL2.1.10 • Engine Control Board, PL1.1.4
Remedy:	1 Test the Fuser Motor. 1. Close the Interlock Switches for test. 2. Run the Service Diagnostics Fuser Motor test. Does the motor operate? Complete. Replace the motor. If the error persists, go to Step 2. 2 Check for +24 V to the Fuser Motor. Is the +24 V across DCHEAT- 3 <=> ground? Go to Step 5. Go to Step 3. 3 Check Motor Driver Board POW24 connector for 24 V. 1. Disconnect POW24. Is the +24 V across POW24 pins 1 and 2? Replace the Motor Driver Board. Go to Step 4. 4 Check for 24 V at the LVPS 1. Disconnect CN2 on the LVPS. Is the +24 V across pins 1 and 2? Replace the POW24 Harness. Replace the LVPS. 5 Check all pins of the DRV1 harness for continuity. Disconnect the DRV1 ribbon cable. Is the cable conductive? Replace the Engine Control Board. Replace the DRV1 Harness.
