Hi @jin825,

I'd like to help!

I understand you are facing printhead errors.

Please try the below suggestions:-

Reset the printer

Reset the printer to recover from printer errors or failures.

1. If your printer has a rechargeable battery, remove it.

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

3. Unplug the power cord from the power source.

4. Wait 60 seconds.

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

   NOTE: 

   HP recommends plugging the printer directly into a wall outlet.

6. Turn on the printer to complete the reset.

Update the printer firmware

HP regularly releases new firmware versions with printer enhancements or issue fixes. Update firmware on a regular basis to make sure you are getting the most out of your printer.

• Update from the printer control panel: Many HP printers with touchscreens or menus can connect directly to HP to find and install updates. Make sure the printer is on a network with an active Internet connection. If the printer is connected with a USB cable, use one of the other options.

  On the printer, locate the Product Update or Check for Updates menu by pressing the HP ePrint icon or button ( or ). Or open the Setup, Service, or Settings menu, select Preferences, Printer Maintenance, or Tools, and then select Web Services, Printer Update, or LaserJet Update.

• Download updates from HP Customer Support: With the printer turned on and connected to the computer or a network, go to HP Software and Driver Downloads to check for and install available updates listed under Firmware.

• Install updates through the HP Smart app: Open the HP Smart app, and then create an account or sign in. If you do not have HP Smart, download it from 123.hp.com or your app store. After adding the printer, click the printer image, click Printer Home Page (EWS) or Advanced Settings, click Tools or Web Services, and then click Printer Updates.

Reseat the printhead if it is replaceable

If your printer has a removable printhead, you can manually reseat it. Otherwise use the steps provided to replace the printhead or service the printer.

1. Open the door or lid to the cartridge access area. Wait until the carriage stops moving before continuing.

2. Look for a latch on the carriage.

   

   • If there is no latch, the printhead is not replaceable. Go to Contact HP Customer Support to schedule a product repair or replacement. If you are in Asia Pacific, you will be directed to a local service center in your area. To confirm your warranty status, go to HP Product Warranty Check. Repair fees might apply for out-of-warranty products.

   • If there is a latch, continue to the next step.

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

4. Lift the carriage latch, slightly lift the printhead, lower the printhead back into the carriage, wiggle the printhead left and right, and then lower the carriage latch until it stops.

   

5. Close the door or lid to the cartridge access area.

6. Reconnect the power cord to the printer.

   If the error message still displays, sometimes the issue persists after inserting the printhead. Repeat the steps to reseat the printhead up to three times, and then continue to the next step if the error still displays.

 If the issue persists, I'd suggest you contact HP in your region regarding the service options for your printer

Hope this helps! Keep me posted.
