"missing or failed printhead" error message

HP Recommended
HP Officejet 6600 All in One
Microsoft Windows 10 (64-bit)

I'm getting the "missing or failed printhead" message for all four relatively new HP cartridges.  They worked fine until I left town for 6 weeks.  I tried powering down the printer, and wiping the print heads.  No help.

Hi @TimothyDL

 

I'd like to help with the printer issue.

 

Try the below steps-

 

Reset the product

  • With the printer turned on, disconnect the power cord from the rear of the printer.
  • Unplug the power cord from the wall outlet.
  • Wait at least 60 seconds.
  • Plug the power cord back into the wall outlet.
  • Reconnect the power cord to the printer.
  • Turn the printer on. HP recommends plugging the printer directly into a wall outlet

 Clean the electrical contacts

 

Remove the cartridge indicated by the error message, clean the electrical contacts, and then reinsert the cartridge in its color-coded slot.

  1. Open the door to access to the cartridges.

  2. Wait until the carriage stops moving before you continue.

  3. Push the tab on the cartridge indicated by the error message, and then pull the cartridge from its slot.

       CAUTION: 

    Clean the cartridges one at a time. Do not leave a cartridge outside of the printer for more than 30 minutes.

  4. Wipe the copper-colored contact on the cartridge with a lint-free cloth.

  5. Place the cartridge to the side, with the contacts facing upwards.

  6. Wipe the contacts inside the printhead with a lint-free cloth.

  7. Insert the cartridge into its slot, and then press down on the cartridge until it snaps into place.

  8. Repeat these steps for any other cartridges indicated in the error message.

  9. Close the front door and cartridge access door

Hope this helps! Keep me posted.
