HP Printer Ink Cartridge Not Recognized — Fix

What Does This Error Mean?

If your HP printer does not recognize a cartridge, remove it, clean the copper contacts with a dry lint-free cloth, and firmly reinsert it. If using a third-party cartridge, HP printers may block it after a firmware update.

Affected Models

HP OfficeJet
HP DeskJet
HP ENVY
HP Photosmart
HP OfficeJet Pro

Common Causes

Dirty or oxidised copper contacts on the cartridge or carriage
Third-party or refilled cartridge blocked by a recent firmware update
Cartridge not fully seated in the carriage
Damaged cartridge chip
Faulty carriage contact spring in the printer

How to Fix It

Remove the cartridge and clean the contacts.

Open the cartridge access door and remove the cartridge. Using a dry, lint-free cloth, gently wipe the copper-coloured contacts on the bottom of the cartridge. Also wipe the corresponding contacts inside the carriage slot. Reinsert firmly.
Reseat the cartridge firmly.

Push the cartridge down into the slot until you hear or feel a click. A partially seated cartridge will not be recognised. Close the access door and wait 30 seconds for the printer to detect the cartridge.
Power cycle the printer.

Switch off the printer, unplug it from the wall for 60 seconds, then plug back in and power on. A power cycle sometimes clears a cartridge recognition error caused by a temporary controller glitch.
Check the firmware version if using third-party cartridges.

HP regularly releases firmware updates that block non-HP cartridges. If the error appeared after a recent firmware update, you can roll back the firmware via the HP printer software on your computer, or switch to genuine HP cartridges.

When to Call a Professional

If cleaning the contacts and reseating the cartridge does not help, and the cartridge is genuine HP, the carriage contact spring may be damaged — contact HP support or a service centre.
