Thanks for sending out the 4880 LK cartridge, that did the trick. But now I’m getting the same ‘set ink cartridge’ error with the PK. I was running prints fine, then the printer said I needed to replace the PK cartridge. It was still half full with in, so I reset the chip and when I put it back in the error message came back.
Is it something I’m doing wrong with the chip or resetting the chip? Or is it simply that the cartridge isn’t fitting properly into the printer?
