Welcome to the HP support community.

 

I understand that you are getting a paper jam error, I am glad to assist you.

Reset the printer

  • Sometimes a paper jam error persists even though there is no jammed paper (false paper jam). Reset the printer, which might clear a false paper jam error, and then try to print again.
  • With the printer turned on, disconnect the power cord from the printer.
  • Unplug the power cord from the power source.
  • Wait 60 seconds.
  • Reconnect the power cord to a wall outlet and to the printer.
  • NOTE: HP recommends plugging the printer directly into a wall outlet.

Clean the paper feed rollers

  • Clean the rollers inside the ink cartridge access area.
  • Turn off the printer, and then disconnect the power cord and any other cables.
  •   WARNING: You must disconnect the power cord before reaching inside the printer to avoid risk of injuries or electric shock.
  • Open the ink cartridge access door.
  • Figure : Opening the ink cartridge access door
  • Example of opening the ink cartridge access door
  • Lightly dampen a lint-free cloth with distilled water, and then squeeze any excess liquid from the cloth.
  • Move the carriage all the way to the right, if necessary.
  • Press the cloth 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 completely (approximately 10 minutes).
