Question about HP LaserJet 2840 All-In-One Printer
I have had a paper jam in my HP2840. I have removed the fuser, drum and checked everywhere I can find along the paper path. I cannot find the paper (which was very thin W-2s). I no longer have the paper jam error code, but the print quality is really bad (smudging, etc). I never found the paper. Is there anything else I can take apart? Has my fuser or something else been damaged?
If the toner wipes off the printed pages, then the fuser is the problem....not hot enough or enough pressure to heat the toner to the paper. I would try to reseat the fuser...make sure it is making good electrical contact. I have also seen the paper actually wrap around the fuser roll, which would cause the same symptoms...be careful removing the paper if that has happened...the fuser roll can be easily damaged !

Make sure that the printer is turned off.
Open the printer cover by pressing the latch on the left side of the printer and lifting the cover up all the way.
Warning: Opening the printer cover exposes the fuser, which is marked CAUTION Hot Surface Avoid Contact. Be careful not to touch the fuser. If the printer has been in use, the fuser may be very hot.
1. CAUTION Hot Surface Avoid Contact
Remove the developer cartridge.
Caution: When removing the developer cartridge, never touch the developing roller under the flap; otherwise, print quality may decline.
Remove the photoconductor unit.
Caution: Never touch the photoconductor unit's light-sensitive drum; otherwise, print quality may decline.
Remove the paper from the paper path.
Note: If paper is jammed at the fuser, grasp the bottom of the paper and pull it out.
Reinstall the photoconductor unit, and then the developer cartridge.
Close the printer cover.
Tap the edges of the stack of paper on a flat surface and carefully reload it into the MP tray. (Do not reload curled or wrinkled sheets.)
Printing automatically restarts from the page that jammed. If the Paper light stays on after removing all jammed paper, open and close the printer cover to clear the error.
