Take out the toner cartridge, fuser, transfer roller, etc, and blow all the dust and crud out of the paper path. Check that the transfer roller bushings are good and that it turns freely. Check that there's not a bit of paper stuck in the registration assembly. There are also two sensor flags in the fuser (an entry and an exit). Check to be sure that a bit of fuser hasn't gotten stuck in them... Also, if I remember correctly, there's a little conveyor belt looking thing in there too - make sure nothing is preventing it from moving freely. Honestly, with some of these printers, I wind up taking out the paper tray, the fuser, toner, everything you can easily remove, and turn them upside down and shake. It's amazing the crud that falls into a printer. I fixed a nagging jam problem in one machine by just

Thanks for the info.  I'll have another look at it tonight.

I remember the shake-the-printer-upsidedown trick from laserjet 2s and
3s.  Those printers would literally unscrew themselves.  Screws would
work their way out and fall into the mechanism.
