Tips to prevent paper jams

To reduce the number of paper jams, try these solutions.

Use only paper that meets HP specifications for this product.
Use paper that is not wrinkled, folded, or damaged. If necessary, use paper from a different package.
Use paper that has not previously been printed or copied on.
Make sure the tray is not overfilled. If it is, remove the entire stack of paper from the tray, straighten the stack, and then return some of the paper to the tray.
Make sure the paper guides in the tray are adjusted correctly for the size of paper. Adjust the guides so they are touching the paper stack without bending it.
If you are printing on heavy, embossed, or perforated paper, use the manual feed feature and feed sheets one at a time.

Clear a jam in the cartridge area

A jam in the cartridge area usually indicates that there is packing material remaining in the printer. See HP LaserJet Pro 400 M401 and M425 MFP - "Jam in Cartridge Area / Open door and clear jam."
