Re: Printhead Missing, Not Detected or Incorrectly Installed 0xc19a0023

Hi @dickch03,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The error 0xc19a0023 typically indicates a printhead failure or communication issue between the printhead and the printer. Since repeating the troubleshooting steps worked the first time but not now, it's possible the printhead has permanently failed or there's an issue with the printer’s internal components.
 

Since you've already tried basic troubleshooting, try these advanced steps:

Perform a Hard Reset

1. Turn off the printer.
2. Unplug the power cord from the wall outlet and printer.
3. Wait 5–10 minutes.
4. Plug the printer back in directly to a wall outlet (avoid surge protectors).
5. Turn on the printer and check if the error persists.

Check the Printhead Installation

1. Open the printer cover.
2. Remove all ink cartridges.
3. Lift the latch securing the printhead.
4. Take out the printhead and inspect the contacts for any ink buildup or damage.
5. Wipe the printhead’s gold contacts with a lint-free cloth slightly dampened with distilled water or isopropyl alcohol.
6. Reseat the printhead firmly.
7. Reinstall ink cartridges and close the cover.
8. Restart the printer.

Update Firmware

If your printer has outdated firmware, it might cause printhead detection issues.

• Visit HP Support and download the latest firmware for your printer.
• Install the update following the instructions.

Try a Different Ink Cartridge

• Sometimes, faulty cartridges can trigger printhead errors. Try replacing the cartridges with new genuine HP ink.

Perform a Semi-Full Reset (Factory Reset)

1. Turn off the printer.
2. Press and hold the Power button and Resume (or Cancel) button together.
3. Hold them for 10-15 seconds until the printer resets.
4. Release the buttons and wait for the printer to restart.

I hope this helps.

Take care and have a good day.
