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.
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.
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. Pull out the input tray, and then remove any jammed paper.
If the paper is even slightly askew, the rollers will pick it up a little crooked, and — guess what — the crooked sheet will immediately get jammed. So even though there`s no paper stuck when you start printing, the loose paper guides are ensuring that a sheet gets jammed whenever the printer starts doing its thing.

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.

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.
