Common causes of jams
Common causes of jams 1
Cause Solution
The media does not meet specifications. Use only media that meets HP specifications. See Supported
media sizes .
A component is installed incorrectly. Verify that all print cartridges, the transfer unit, and the fuser
are correctly installed.
You are using media that has already passed through a printer
or copier. Do not use media that has been previously printed on or
copied.
An input tray is loaded incorrectly. Remove any excess media from the input tray. Make sure that
the stack is below the maximum stack height mark in the tray.
See
Configuring trays .
The media is skewed. The input-tray guides are not adjusted correctly. Adjust them
so they hold the stack firmly in place without bending it.
The media is binding or sticking together. Remove the media, flex it, rotate it 180 degrees, or flip it over.
Reload the media into the input tray.
NOTE Do not fan paper. Fanning can create static
electricity, which can cause paper to stick together.
The media is removed before it settles into the output bin. Reset the printer. Wait until the page completely settles in the
output bin before removing it.
During 2-sided printing, you removed the paper before the
second side of the document was printed. Reset the printer and print the document again. Wait until the
page completely settles in the output bin before removing it.
The media is in poor condition. Replace the media.
The internal rollers from tray 2 or tray 3 are not picking up the
media. Remove the top sheet of media. If the media is heavier than
163 g/m
2 (43 lb), it might not be picked from the tray.
The media has rough or jagged edges. Replace the media.
The media is perforated or embossed. Perforated or embossed media does not separate easily. Feed
single sheets from tray 1.
Printer supply items have reached the end of their useful life. Check the printer control panel for messages prompting you to
replace supplies, or print a supplies status page to verify the
remaining life of the supplies. See
Replacing supplies and
parts .
Paper was not stored correctly. Replace the paper in the trays. Paper should be stored in the
original packaging in a controlled environment.
