Incompatible Cartridge

This printer is not designed to use continuous ink systems. To resume printing, remove continuos ink system and install original HP (or compatible) cartridges.

Does anyone know how to fix this issue

@KOJ_TE_EBA, Welcome to HP Support Community!

Update the printer firmware-

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates. Refer to the document HP Printers - Updating or Upgrading Printer Firmware

The third-party ink cartridges will work. But there are many cartridges in the market which are refilled and sometimes the chip is not configured to work with the printer. You need to contact the cartridge manufacturer and find out why it's not working. Try a different cartridge supplier and check if that works.

I hope that answers your concern adequately. Let me know!
