Question about HP LaserJet 4250n Printer
The proper thing to do here is replace the swing plate assembly rm1-0043 with the OEM part. Otherwise, you'll end up in the same situation in half the time. Only a seasoned technician can perform this task as the printer needs to be completely dismantled. 30 minute job if you've done this 20 times before. 2 hour job if you've never done it before.

This is a very common problem for this model ... the swing plate assembly has a black gear which in particular is prone to wearing out ... originally the design was a plastic gear, PrinterTechs has a metal gear replacement which is sturdier ...

Actually, TSAworld offers a simple solution to this very common problem with HP LaserJet 4200, 4250, 4345 and 4350 models; "gear chatter" or grinding noises. The problem is caused by the fuser drive gear mechanism, commonly called the "swing plate assembly". We sell a kit which contains aftermarket components to rebuild the existing swing plate assembly and the fuser gear. As long as the actual swing plate assembly is not bent or the spring is not missing for damaged, then fixing this problem literally takes about 15-20 minutes by following our detailed instructions included with each kit. Arm yourself with a simple, quick, and cost-effective solution. Plus we sell lots of other kits for taking care of many other common issues with printers and copiers.

Remove the fuser from the rear of the printer and look on the left side from the rear. Most comon problem is that the swingplate gear wears down so much that the gears slip and grind. If you see a pile of black powder under this gear plate this is for sure the problem. Complex repair job. Lots of dis-assembly is required.

It needs to be looked at by a technician to see it there are any broken gears in it.
