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.
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.
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.
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.
With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet. Remove USB cable, if present. Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
A paper jam is when paper or other printed material gets stuck or lodged in a printer and cannot eject.
Lift the document feeder input tray to access to the document feeder output tray, and then remove any jammed paper from the output area. To avoid tearing any whole sheets of paper, pull the paper with both hands. Open the scanner lid. If there is paper jammed behind the white plastic backing, gently pull it out.
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.

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.

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.
