Re: HP Envy 5660 makes grinding noise when printing

Welcome to HP support community.

Manually clean the paper feed rollers

1. Gather the following materials:

   • Long, lint-free cotton swabs

   • A clean, lint-free cloth, or any cloth that does not come apart or leave fibers

   • Distilled, filtered, or bottled water (tap water might damage the printer)

2. Turn on the printer, if it is not already on.

3. Gently grasp the handles on either side of the printer, then raise the ink cartridge access door until it locks into place.

   The carriage moves to the center of the printer.

4. Wait until the printer is idle and silent before you continue.

5. While the printer is still on, disconnect the power cord from the rear of the printer, and then unplug the power cord from the power source or electrical outlet.

      WARNING: 

   You must disconnect the power cord before reaching inside the printer to avoid the risk of injuries or electric shock.

6. Disconnect the USB cable from the rear of the printer, if you have a cable connection to the computer.

7. Locate the paper path cover, grasp the handle, and then lift up to remove it.

8. Lightly dampen the swab with the water, and then squeeze any excess liquid from the swab.

9. Use a flashlight to inspect the rollers. 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.

10. Allow the rollers to dry completely (approximately 10 minutes).

11. Replace the paper path cover, and then close the ink cartridge access door.

16. Lightly dampen a clean, lint-free cloth with bottled or distilled water, and then squeeze any excess liquid from the cloth.

17. Inspect the gap where the input tray was with a flashlight. Press the cloth against the rollers, and then rotate them upward with your fingers. Apply a moderate amount of pressure to remove any dust or dirt buildup.

18. Allow the rollers to dry completely (approximately 10 minutes).

19. Push in the input tray, and then return the printer to its normal position.

20. Slide the output tray back onto the input tray.

21. Reconnect the power cord to the rear of the printer, and then plug in the power cord to an electrical outlet.
