Question about HP LaserJet 4100n Printer
I have an HP LJ 4100n that is constantly jamming with "13.1 paper jam, open input trays then open and close top cover." i tried a maintenance kit, but that didnt help. it looks like it is only doing it on multi page prints. i was watching it pick up paper from the back and after 1 or 2 good pages, the semicircular pickup rollers in the tray start spinning more than once per page. On the second page after this starts, it picks up and shoves the next page under the page before it and the printer instantly jams with that error message. Any suggestions on how to fix this?

Try this, make a print from the by-pass tray, does it go OK or jam??
If it jams then there is a problem with the paper feed from the tray.
If it jams then
1-check the drum and see if there is an image on it( you can put a mark on the edge to see if it's rotating, thus eliminating the drum unit)
2-same for the reg roller
3-check for labels ar foreign objects

You need the pick up rollers replaced. Call your service centre to replace pick rollers as these are feeding the pages crocked
