Sometimes a paper jam error persists even though there is no jammed paper (false paper jam). Reset the printer, which might clear a false paper jam error, and then try to print again. With the printer turned on, disconnect the power cord from the printer. Unplug the power cord from the power source.
Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues. Clean the rollers inside the printer, and then try to print again. Turn off the printer, and then disconnect the power cord.

During a print job, the printer stops feeding pages, and a Paper Jam error message displays on the printer control panel. This indicates that paper might be jammed inside the printer. note: Paper jams can be real or false. The printer might report a paper jam even when there is no jammed paper.
Do a hard reset on your printer. To do this you just need to turn off your printer, unplug for a few minutes and then plug the printer again. If that still doesn`t work, try turning the printer and your computer off, and then start it back up again. Try uninstalling and then reinstalling your printer driver.

Paper jam in tray 2 (but no paper pulled from tray) also M476DN models
ANSWER : Isopropyl alcohol is not recommended for rubber rollers. It dries out the rubber and hasten it’s cracking and breaking. It will do nothing to restore the grip. Those rollers are really hard to replace. It would be easy if that dumbass secondary menu really worked. None of the techs I’ve spoke to ever got into it. Everyone I know sends a print job and listens for the roller to rotate into position where you can pull it off.

HP LaserJet 4200 paper jam fix
ANSWER : Yes, thank you! You did a thorough post! If your still hacking away at HP’printers you will know that unfortunately HP kept using that type of solenoid with the “Sticky Mess” on all of their new Equipment. I use this method almost everyday (without removing the actual solenoid). I’ve replaced so many I got carried away and now, I sell a solenoid repair kit! It’s for those people that like convenience. I provide a professional supply of perfect material with sticky back tape pre-cut to exact dimensions! All in a little kit. I have install videos, (I don’t charge for that I believe in the Do-it -Yourself approach.) Sorry for the sales pitch… but here is my link.

Paper Jam error but no paper jam
ANSWER : Obviously you didn’t get all the paper cleared out. There is a small scrap in the paper path causing the jam when the paper hits it. You can try clearing it out by inserting something stiff like a piece of file folder from the back of the printer into the paper path and pushing the offending piece out that way.

HP Officejet Pro 8500 Wireless with fake paper jam
ANSWER : HP Officejet is by far one of the frustrating piece of equipment I have ever owned. I bought it as unused in the package, at that point no warranty left. less than 6 months and 500 pages the white cog gear wheel broke. Luckily with instructions in this site I manage to glue it back together. Then I bought new ink – problems started as they were not original HP 30$ per cartridge. Ordered originals (here in China), took over one week to get them. Then found out that printhead needed to be replaced => more than 100$ spent. Still constant problems: If my wife kids print, I need to be stand-by as you never know what happens. Really an Office level equipment. After cleaning one paper jam I broke the encoder tape, took me another 4 hours to get it fixed. Then broke the cog gear again and got it displaced. Another 4 hours. Only reason I am not throwing this s***t out of window is that there are still ink left. Luckily this drinks them like a horse, for sure I will no more buy new ink. I will get a new laser instead, and not from HP. About cog wheel fixing: make sure that the white wheel is positioned correctly so that the small torx in shaft goes into the slit in the white wheel. When fitting the black cover back, make sure that the white washers on both sides fit into to slits of the black cover. Good luck.
