English Solving repeated paper jams  Check all the paper jam locations (see "Paper jams" on page 1- 52). A piece of paper might be stuck somewhere in the printer. Even a small torn piece of paper in the printer path can cause repeated jams.  If using a duplexer, check all areas (including under the duplexer).  Check that paper is correctly loaded in the trays, that all three adjustments have been made, and that the trays are not overfilled. Make sure paper is under the front and back tabs. See the sections on loading paper (pages 1-18 and 1-19).  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 reducing the size of the stack.  If printing from the envelope feeder, make sure it is loaded correctly, pushing the bottom envelopes in slightly farther than the top envelopes.  If you are printing small sizes, feed paper short edge first.  Turn over the stack of paper in the tray. Also try rotating the paper 180°.  Check the characteristics of the media you are using. Use only paper that meets HP specifications (see the online user guide for paper specifications). Try using different paper to see if the problem goes away. Do not use curled, deformed, damaged, or irregular paper.  Avoid using paper that has already been used in a printer or copier.  Do not print on both sides of envelopes or transparencies.  Print only on full sheets of labels and do not print on both sides of label sheets.  Check that the power supplied to the printer is steady and meets printer specifications (see the online user guide for printer specifications).

Solving repeated paper jams
Check all the paper jam locations (see “Paper jams” on page 1-
52). A piece of paper might be stuck somewhere in the printer.
Even a small torn piece of paper in the printer path can cause
repeated jams.
If using a duplexer, check all areas (including under the duplexer).
Check that paper is correctly loaded in the trays, that all three
adjustments have been made, and that the trays are not
overfilled. Make sure paper is under the front and back tabs. See
the sections on loading paper (pages 1-18 and 1-19).
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 reducing the size of the stack.
If printing from the envelope feeder, make sure it is loaded
correctly, pushing the bottom envelopes in slightly farther than the
top envelopes.
If you are printing small sizes, feed paper short edge first.
Turn over the stack of paper in the tray. Also try rotating the paper
180°.
Check the characteristics of the media you are using. Use only
paper that meets HP specifications (see the online user guide for
paper specifications). Try using different paper to see if the
problem goes away. Do not use curled, deformed, damaged, or
irregular paper.
Avoid using paper that has already been used in a printer or
copier.
Do not print on both sides of envelopes or transparencies.
Print only on full sheets of labels and do not print on both sides of
label sheets.
Check that the power supplied to the printer is steady and meets
printer specifications (see the online user guide for printer
specifications).
Clean the printer (see the online user guide procedures).
Perform preventative printer maintenance if maintenance is due
(see the online user guide for details).
