@fmacaluso, Welcome to the HP Support Community! I’m here to help.


I understand the ink cartridge is not working. To assist you better, do you get any errors?

Insert the old ink cartridge to check for the error. By this, we can conclude if the new ink cartridges are defective.

Check for the plastic tape if any, is removed from the new ink cartridge before placing it in the printer.


Make sure the ink cartridges are properly inserted in the printer, you may refer to - Replace HP inkjet printer cartridges

Note: Use HP ink cartridges.


Kindly perform the steps mentioned in this document - Ink cartridge error


If the error persists even after using multiple ink cartridges, please reach out to the HP Technical Support team in your region regarding the replacement options for the printer.

You may create a case on the website to obtain a case number if required. Kindly watch this video to know how.


Keep me posted for any other assistance.
