Common causes of paper jams


Common causes of paper jams

The following table lists common causes of paper jams and suggested solutions for resolving them.

Common causes of paper jams1

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.

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/m2 (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.

Common causes of paper jams (continued)

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 for more information.
Paper was not stored correctly. Replace the print paper. Paper should be stored in the original packaging in a controlled environment.

1 If the printer still continues to jam, contact HP Customer Support or your authorized HP service provider. For more information, see for the HP Color LaserJet 3550 series printer and for the HP Color LaserJet 3700 series printer.
