During printing, the printer stops feeding pages and the error message Paper Jam displays on the printer control panel. The control panel might also display a brief description of how to remove the jammed paper.

note:
Paper jams can be real or false. The printer might report a paper jam even when there is no jammed paper. The following steps apply to both real and false paper jams.

Step 1: Look for jammed paper

Paper jams can occur in multiple areas of the printer. If you cannot find the paper jam in one area, continue to the next area until you locate the jam.

Clear jammed paper from the ink cartridge access area, the rear rollers, and the duplexer

Remove any jammed paper that is accessible from the ink cartridge access area, rear rollers, and duplexer area.

With the printer turned on, disconnect the power cord from the rear of the printer.

warning:
You must disconnect the power cord before reaching inside the printer to avoid the risk of injuries or electric shock.
Locate the slots on the left and right sides of the printer.
Slide your fingers into the two slots, and then gently lift up to open the ink cartridge access door.
Remove any jammed paper from the ink cartridge access area, located toward the front of the printer. To avoid tearing any whole sheets of paper, pull the paper with both hands.

note:
Use a flashlight to thoroughly check for torn pieces of paper that might remain inside the printer. If any torn pieces of paper remain inside the printer, more jams might occur.
Locate the paper path cover, in the area behind the ink cartridge access area.
To remove the paper path cover, pinch the tabs together, and then lift up.

Try to print. If the error persists, check for jammed paper in another area of the printer.

Clear jammed paper from underneath the printer

Remove any jammed paper from under the printer, and then make sure the printer is on a flat surface, clear of obstructions.

Gently turn the printer onto its right side.
Check the surface directly under and around where the printer sits for the following:
- Pieces of paper trapped in the input tray
- Small, hard objects, such as cables, pens, pencils, and books
- Soft or uneven surfaces, such as placemats or carpet-like material
Remove any obstructions that might remain.
Turn the printer to its normal position.
Reconnect the power cord to the rear of the printer, and then turn on the printer.

Clear jammed paper from the input tray

Remove any jammed paper that is accessible from the input tray area.

Pull out the input tray
Remove any loose sheets of paper from the tray.
Gently remove any jammed paper and bits of torn paper from the tray. To avoid tearing any whole sheets of paper, pull the paper with both hands.
Check for torn pieces of paper that might remain inside the tray. If any torn pieces of paper remain inside the printer, more jams might occur.
Grasp the front of the paper tray, and then push it back until you hear it click into place.
Remove the paper from the tray, and then turn off the printer.
Wait for 30 seconds, and then turn on the printer.

If you have checked and removed any jammed paper from each printer area and the error persists, continue to the next step.

Step 2: Clean the paper rollers

Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues.

Turn off the printer if it is not off already.

Lightly dampen a lint-free swab with distilled or bottled water, and then squeeze any excess liquid from the swab.
Press the swab against the rollers inside the printer, and then rotate the rollers upwards with your fingers. Apply a moderate amount of pressure to remove any dust or dirt buildup.
Allow the rollers to dry for 10 to 15 minutes.
Check the rollers on the underside of the paper path cover. Make sure the rollers are not missing, that they turn easily, and that they are springy when you press them. If the rollers are damaged, replace the paper path cover with a new one.
