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.)
• Check that all covers and doors are closed. (If a
cover or door is opened during a print job, this might
cause a paper jam.)
• Try printing to a different output bin.
• The sheets might be sticking together. Try bending
the stack to separate each sheet. Do not fan the
stack.
• If you are printing from Tray 1, try feeding fewer
sheets of paper or fewer envelopes at a time.
• If you are printing from the envelope feeder, make
sure it is loaded correctly, pushing the bottom
envelope in slightly farther than the top envelopes.
Continued on the next page.
EN
Paper Jams – 23
• 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.
• Avoid using paper that has already been used in a
printer or copier. (Do not print on both sides of
envelopes, transparencies, or labels.)
• Check that the power supplied to the printer is
steady, and meets printer specifications.
• Clean the printer as shown in the online user’s
guide.
• Perform routine printer maintenance. Order the
Printer Maintenance Kit. See the online user’s
guide that came with the printer.
