Common causes of paper jams 1
Cause Solution
Paper does not meet HP-recommended paper
specifications. Use only paper that meets HP specifications.
See
Supported paper weights and sizes .
A supply item is installed incorrectly, causing
repeated jams. Verify that all print cartridges, the transfer unit,
and the fuser are correctly installed.
You are reloading paper that has already passed
through a printer or copier. Do not use paper that has been previously
printed on or copied.
An input tray is loaded incorrectly. Remove any excess paper from the input tray.
Be sure that the paper does not exceed the
maximum stack height mark in the input tray.
See
Configuring trays .
Paper is skewed. Input tray guides are not adjusted correctly.
Adjust input tray guides so they hold paper firmly
in place without bending it.
Paper is binding or sticking together. Remove paper, flex it, rotate it 180 degrees, or
flip it over. Reload paper into the input tray.
NOTE
Do not fan paper. Fanning can create static
electricity, which can cause paper to stick
together.
Paper 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.
When duplexing, the paper is removed before
the second side of the document is printed. Reset the printer and print the document again.
Wait until the page completely settles in the
output bin before removing it.
Paper is in poor condition. Replace the paper.
Paper is not picked up by the internal rollers
from Tray 2 or Tray 3. Remove the top sheet of paper. If the paper is
heavier than 105 g/m
2 (28 lb), it may not be
picked from the tray.
Paper has rough or jagged edges. Replace the paper.
Paper is perforated or embossed. This paper does not separate easily. You might
need to feed single sheets from Tray 1.
