@Cheche-17, Welcome to HP Support Community!

Follow the steps below-

Clean the paper rollers

Use an automated utility to clean the paper feed rollers inside the printer.

1. Turn on printer.

2. Remove paper from the input tray.

3. Press and hold the Power button, press the Cancel button three times, press the Start Copy Color button seven times, and then release the Power button.

   The printer makes mechanical noises. Wait until the printer is idle and silent before you proceed.

Try to print. If the error persists, continue to the next step

.

Clean ink smears

Cleaning ink smears can help clear paper jams and optimize print quality.

1. Press and hold the Power button, press the Cancel button three times, press the Start Copy Color button eight times, and then release the Power button.

   The printer feeds one page slowly and makes mechanical noises.

2. Wait until the printer is idle and silent before you proceed.

Try to print. If the error persists, continue to the next step.

Manually clean the paper rollers inside the input tray area

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

1. Turn off the printer, and then disconnect the power cord.

      WARNING: 

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

2. Disconnect the USB cable, if it is connected.

3. Raise the input tray.

   

4. Lift and hold the input tray shield.

   NOTE: 

   Do not remove the input tray shield. The input tray shield prevents foreign debris from falling into the paper path and causing paper jams.

5. Use a flashlight to look through the open input tray and find the gray paper pick rollers.

   

6. Dampen a long cotton swab with bottled or distilled water, and then squeeze any excess water from the swab.

7. Press the swab against the rollers, and then rotate them upward with your fingers. Apply a moderate amount of pressure to remove dust or dirt buildup.

8. Lower the input tray shield.

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

10. Reconnect the USB cable to the printer if necessary.

11. Reconnect the power cord to the rear of the printer, and then turn on the printer.

Try to print. If the error persists, continue to the next step.

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.

1. With the printer turned on, disconnect the power cord from the printer.

2. Unplug the power cord from the power source.

3. Wait 60 seconds.

4. Reconnect the power cord to a wall outlet and to the printer.

Try printing.
