Improperly Loading Paper into the Device

Loading paper that is stuck together, frayed, curled or bent can cause a jam. Overloading the paper tray, loading different thicknesses of paper in the tray or using paper that isn`t appropriate for your particular printer can all result in a jammed printer.

Dust, dirt, or debris: Not cleaning the HP Printer can also result in a paper jam error. So, if you find that no paper is stuck but a paper jam error showing, you must check for the dirt or dust on the device.
The following are the top reasons why paper jams occur:

unsupported paper/media is used. incorrect paper settings in the tray and/or the print driver. paper loaded incorrectly and/or paper edge guides not adjusted properly in the tray. humidity and/or paper condition and storage.

A piece of paper stuck in the paper tray or inside the printer can create a paper jam. Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer.
Open the access door, move the carriage if necessary, and then remove any jammed paper. On some Laserjet printers, you might need to remove the toner cartridge and/or imaging drum to access the paper jam. If your printer has a paper path cover behind the carriage, remove the cover, and then remove any 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
ANSWER : If you remove the fuser (2 screws), look to the left and you’ll see a gear on a metal bracket. That’s the coupling gear. It drives the fuser. You’ll see that it is yellow with teeth missing. You’ll need to replace it. You have to take the formatter assy. to the left of it off, and then there are a few screws holding it in place.

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.

Paper Jam 13
ANSWER : Sticky paper pickup solenoid. Since MF tray doesn’t use it, it works fine. Solenoid is located on right side of printer at the end of the paper pickup roller shaft. You need to remove the solenoid, take the plate and spring off the top and then scrape off the gooey residue that’s causing it to stick. Then you get a thin piece of sticky backed felt and put it on top of the metal base. You can find some at the local hardware store, they’re used on the bottom of chair legs.

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.
