HP LaserJet 5 - Grinding Noise And Paper Jamming

A grinding noise and paper jamming at the fuser in a Hewlett Packard LaserJet 5 is more than likely caused by the drive train gear cluster.

Open the rear door on the printer, remove two screws, and then pull the fuser out. Shine a torch into the back of the printer and look at the condition of the gear that drives the fuser. You might see that some of the teeth on this gear are worn or completely missing.

The part number for the drive train gear cluster is RG5-0876-050CN. Hewlett Packard list this part as discontinued but you might be able to find a supplier that can sell you one.

Before you buy this part, check the condition of the fuser. Check the gears and the surace of the heater roller. If the fuser is worn as well, you will need to price this up as well. Bearing in mind that this printer is now over ten years old and probably in need of a complete clean and service , it might be time to buy a new model.

If you decide to replace the part, this is what's involved:

1. Remove the fuser as previously described
2. Undo one screw at the back of the right side cover and slide the cover off
3. Undo the screw on the memory cover on the formatter assembly and remove the cover
4. Remove four screws on the side and two at the back of the formatter assembly and pull the formatter assembly off
5. Remove one cable and four screws from the main motor and then lift the motor away
6. Remove two screws and the drive train gear cluster will slide out the back of the printer

 Before fitting the new part, check that it is lubricated. If not, apply some grease to the gears. Also, make sure it is seated properly before fitting and tightening the screws.
