This is a great place to get support, find answers to your technical queries.

I understand that the printer has an error "Reinstall printhead"

Step 1: Reset the printer

Resetting the printing mechanism might resolve the error.

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

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

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

4. Unplug the power cord from the wall outlet.

5. Wait at least 60 seconds.

6. Plug the power cord back into the wall outlet.

     note:

   HP recommends connecting the printer power cord directly to the wall outlet.

7. Reconnect the power cord to the rear of the printer.

8. Turn on the printer, if it does not automatically turn on.

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

Try to print. If these steps resolved the issue, you do not need to continue troubleshooting.

Step 2: Unseat the printhead

Unseat the printhead from the carriage, and then reseat the printhead.

  note:

You do not need to remove the printhead from the carriage.

1. Open the ink cartridge access door.

2. Unplug the power cord from the rear of the printer. Unplugging the printer prevents the carriage from moving.

     warning:

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

3. Lift the carriage latch.

4. Grasp the sides of the printhead, and then slightly lift the printhead without fully removing it from the carriage.

Step 3: Reseat the printhead, and then lower the carriage latch

Reseat the printhead to make sure the printhead and carriage contacts are positioned correctly.

1. Reinsert the printhead into the carriage to reseat it. As you guide the printhead into the carriage, it settles into the carriage as it seats.

2. Gently rock the printhead to the left and right to make sure the printhead fully seats in the carriage.

3. Lower the carriage latch.

4. Make sure the carriage latch is down.

   1. Carriage latch is up

   2. Carriage latch is down

5. Close the ink cartridge access door.

6. Reconnect the power cord to the rear of the printer.

7. If the printer does not turn on by itself, press the Power button to turn it on.

8. Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

Try to print. If these steps resolved the issue, you do not need to continue troubleshooting.

Step 4: Reseat the printhead up to three times

Sometimes error messages persist after inserting the printhead. To clear any error messages, repeat the previous steps to reseat the printhead up to three times.

Examples of error messages on the printer control panel:

Problem with Ink System

Printhead Problem

Ink System Failure

Printer Failure

Carriage Jam

• Try to print. If these steps resolved the issue, you do not need to continue troubleshooting.

• If the error messages persist or change, continue to the next step.

Step 5: Remove the ink cartridges, and then check the error message

Removing the ink cartridges and checking for an error message can help diagnose the printer issue. Remove the ink cartridges, and then check for the error message.

1. Open the ink cartridge access door.

2. Make sure the colored dot and letter on the ink cartridge label matches the correct carriage slot.

3. Push in on the front of the ink cartridge to release it, and then pull the ink cartridge toward you to remove it from its slot.

4. Repeat these steps for the other ink cartridges.

5. Close the ink cartridge access door.

6. Look at the control panel.

   • If the printer displays a The printhead appears to be missing, not detected, or incorrectly installed. message on the control panel, then skip to the step to update the printer firmware.

   • If the message has changed to Replace [K/C/M/Y] Ink Cartridge then continue to the next step.

Step 6: Clean the ink cartridge contacts, and then check the error message

Cleaning the ink cartridge contacts, and replacing the ink cartridges one at a time can help determine if a specific ink cartridge is causing the error message.

1. Open the ink cartridge access door.

2. Lightly dampen a clean, lint-free cloth with bottled or distilled water.

3. Gently wipe the copper-colored contact on the ink cartridge.

4. Wipe the contact with a dry lint-free cloth.

5. Wait at least 10 minutes for the cartridge to dry before proceeding to the next step

6. Repeat the cleaning steps for all of the ink cartridges.

7. Carefully reinsert one of the ink cartridges into its slot, and then push the ink cartridge forward until it snaps into place.

8. Close the ink cartridge access door.

9. Check the printer control panel to see if the error message persists.

   • If The printhead appears to be missing, not detected, or incorrectly installed. displays, replace the ink cartridge that was just reinstalled.

     The test has determined that the reinstalled ink cartridge was causing the problem.

   • If the Replace [K/C/M/Y] Ink Cartridge displays, repeat steps 5-7 for the three remaining ink cartridges.
