1 | Fuser Assembly | Check the fuser assembly internal drive gears | |
| Fuser Drive Motor | for binding, or broken or worn teeth. If a | |
| problem exists, repair or replace the fuser | ||

| Feed Motor Carriage | Remove the fuser drive motor from the stay | |
| Unit Motor Cable | assembly, leaving the motor cable connected | |
| Engine Board | to the motor. Turn the printer on, but do not | |
| allow the motor to touch other areas of the | ||
|
| printer. Verify the motor turns during POR. If it | |
|
| does, the problem is most likely in the motor | |
|
| mounting stay assembly. Go to step 2. | |
|
| Check the motor for shorts between the case | |
|
| and each motor winding. If a short is found, | |
|
| replace the motor. | |
|
| Note: Damage to the engine board may result | |
|
| from a shorted motor. | |
|
| Check the motor for open windings. If found, | |
|
| replace the motor. | |
|
| Check continuity of the fuser motor/paper | |
|
| feed motor/carriage unit motor cable. | |
