							Clear jams
When clearing jams, be careful not to tear jammed paper. If a small piece of paper remains in the product,
it could cause more jams.
Common causes of jams
●The input tray is loaded incorrectly or is too full.
NOTE:
When you add new paper, always remove all of the paper from the input tray and
straighten the entire stack. This helps prevent multiple feeds and reduces jams.
● The paper does not meet HP specifications.
● The product might need to be cleaned to remove paper dust and other particles from the paper
path.
Loose toner might remain in the product after a jam. This toner clears up after a few sheets print.
CAUTION: If you get any toner on your clothes, wash them in cold water.  Hot water permanently sets
toner into the fabric .
