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.
Common causes of paper jams include: Damaged rollers. Inserting paper that is incompatible with the printer. Loading the paper incorrectly.
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 your printer has a bottom cleanout door, carefully lift the printer and look under it, and then remove any jammed paper from the bottom cleanout.
If your printer keeps jamming, you should know that the most common cause of a jam is misalignment of the paper. Paper needs to load in smoothly, completely flush with the tray. Overfilling the tray is a great way to ensure you will be spending some personal time getting to know the inside of a printer.
this can happen if a small piece of paper is stuck in the paper path or if the rollers have become covered with lacquer from the paper, try cleaning the pickup rollers and the paper path, with a slightly damp cloth (not wet).
A paper jam is when paper or other printed material gets stuck or lodged in a printer and cannot eject.

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 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.

message error: ADF paper jam
ANSWER : There is a thin plastic arm that the paper pushes on. It is spring loaded. If it doesn’t return and unblock the sensor after the paper passes it, you get the paper jam warning. I’m guessing that is the spring you are referring to.
