Officejet 7720 error Continuous Ink System detected

[simemrsa]

HP OfficeJet Pro 7720 (Product No:Y0S18A, firmware: ELLISXLP1N003.2502B.00) will not print, error message reads Continuous Ink System detected. This happened after I performed printhead cleaning because the printed pages where messy and smeared.

I use genuine HP cartridges that came with the printer.

Black ink cartridge might be the cause, it is from the same series (N9H83A) as all the others but HP Smart does not recognize it properly.

Hi @simemrsa,

Welcome to the HP Support Community.
 

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

If you have already tried the recommended troubleshooting steps from the HP website and replaced the ink cartridge head without success, there are a few additional steps you can try to resolve the continuous ink error message on your HP OfficeJet Pro 7720 printer:

Restart the Printer: Turn off your printer, disconnect the power cord, and wait for about 30 seconds. Reconnect the power cord and turn the printer back on. Check if the error message persists.

Check for Firmware Updates: Ensure that your printer has the latest firmware installed. You can usually check for firmware updates through the printer's control panel or the HP website. Updated firmware may resolve compatibility issues and improve printer performance. Click Here

Clean the Cartridge Contacts: Turn off the printer and open the ink cartridge access door. Remove the ink cartridges and clean the electrical contacts on both the cartridges and the printer using a lint-free cloth. Be gentle and avoid touching the nozzles.

Reset the Printer: Resetting the printer might help clear error messages. Click Here

I hope this helps.

Take care and have a good day.
