I have a HP laserjet 2420 that gives me a late paper jam quite often. It needed a maintenance kit, so I bought a kit and installed it, and it still gives me the same error message. Any Ideas on what may be causing this error message?

Hi, check throughout the printer for small pieces of paper stuck, broken sensors etc, clean the rollers in the paper tray 2, check for wear. clean the registration rollers (under a metal flap under the print cartridge) do not clean the transfer roller (the spongey roller sitting under the drum!)
Does it jam at the fuser when doing a single print?
These machines have a Maintenance kit required every 200 000 prints, these MK's include all feed rollers, a transfer roller and the entire fuser assy. To replace the kit fixes all issues I've seen in these printers besides when the cartridge affects print quality.
If it is jamming at the fuser on a single print done via the printer operations panel, and your paper is fresh, it could only be the feed roller having trouble gripping the paper or the fuser not turning/stuffed.
Feed Kit, I have my doubts as to this being your problem
Maintenance Kit Fixes 98% of the time
Was is noisy before it died?
I have seen a few with stuffed fuser drive gears but not many and customers could hear it wearing.
How many prints since last MK? via keypad print a configuration page, count is there ie pages since last maintenance xxxxxx
Make sure the paper tray guides are set against the paper more likely to be the back guide not pushing the paper to the front of the tray. If you have the guides set correctly then place one sheet of paper in the tray and blot some methylated spirits on the leading edge along the page width and close the tray and try printing something.
You will have a jam repeat process 3 or 4 times then open tray and remove paper. Where you soaked the spirits into the paper there should be a grubby mark where the feed roller has rubbed and cleaned. Wipe the tray dry and put fresh paper in then hopefully you will now be able to print. If you cannot then the likely thing is that the paper feed pickup spindle is broken and will need replacing.
