@ckwckw02, Welcome to HP Support Community!

 

Reset the printer

In some cases, removing the ink cartridges and resetting the printer can clear the error message.

  1. Turn on the printer.

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

  3. Disconnect the USB cable from the rear of the printer. If your printer has a network or wireless connection, leave it connected.

  4. Remove the ink cartridges from the printer.

  5. With the printer turned on, disconnect the power cord from the rear of the printer and from the wall outlet or power strip.

  6. Wait at least 60 seconds.

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

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

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

    The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

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

  11. Reinsert the ink cartridges, and then close the ink cartridge access door.

  12. If you receive a prompt to print a calibration page, do so.

  13. If you disconnected the USB cable, reconnect it to the rear of the printer.

  14. Try to print.

Service or replace your HP product if the issue persists after completing all the preceding steps.

Please reach out to the HP Support in your region regarding the service options for your printer.

 

Hope this helps!

I have just recently encountered this error.  I have had this printer at least three years and it was happening until my printer software updated.  I have to cut my printer off and on again to remove the error.  Then, I can continue my projects.  Aggravating!
