The jam might still be inside but you need to be sure all papers are all cleard,ckeck tray 1,where it picks papers carefully,and check the fuser assembly to be sure it not broken and faulty.

HP LJ 4L paper jam light flashes indicating a peper jam after printer makes a grinding noise. What can be the problem?


You may be right about the worn gear as a factor but I used to have a LJ 4 and whenever it indicated a paper jam it was always right. In some cases, the jam was a tiny scrap of paper deep inside. It took a flashlight and examination of every bit of the paper path to find it

HP Officejet 6310 All in One - small paper being faxed is jammed. How do I unjam the paper?


Lift the scanner lid, then lift the black part of the fax - pull up hard for it to lift. Unjam the paper either still on top or gently lift the inner section and retrieve your jammed paper. Then put everything back together and you're right to go again.

Hp 4100 paper is jammed between rollers the back panel should come off? and then how do I get fuser out to unjam paper


Hi Jacque,
I gather the paper has got into the fuser and cannot get into the output bin. Few things...
1. Clean output rollers. Are rollers moving?
2. Check gears on the fuser unit. Any broken or worn gears?
3. Check default paper size setting in printer, paper size setting on tray, paper size setting in printer driver and document page.
4. Leave the back door open. Does the printer still jams? If it does, see it could be paper pick up problem. Use different trays or the manual feed. Also the fuser unit could be the problem.
5. All else fails, replace the output assembly.
