Solving Repeated Paper Jams If paper jams occur frequently, try the following: • • • • • • • • Check all the paper jam locations. A piece of paper might be stuck somewhere in the printer. Check that paper is correctly loaded in the trays, that the trays are correctly adjusted for the loaded paper size, and that the trays are not overfilled. Check that all trays and paper handling accessories are completely inserted into the printer. (If a tray is opened during a print job, this might cause a paper jam.
• • • • • • • • If you are printing small sizes (less than 5 inches long), feed paper short edge first. Turn over the stack of paper in the tray. Also try rotating the paper 180°. Check the quality of the paper being printed. Damaged or irregular paper should not be used. Use only paper that meets HP specifications.
