I have been in the process of switching out my Epson cartridges with the refillable ones for a few months now. As one cartridge runs out I replace it. Everything has been going ok, but today I received a notice that the LLK cartridge was unreadable. I assumed the battery had died (I have the older cartridges, even though I bought them this year). I took out the cartridge (it was almost empty so I refilled it), I replace the battery and I reset the levels. I put the LLK cartridge back in and it told me it could not read the LLK or C cartridge. The C cartridge was an epson one. But it was pretty much empty so I replaced it with a full Epson cartridge. The printer could still not read either of them.
I shut off and turned on the printer. Same issue. I took out LLK and C. Reset ink levels on LLK put it back in with the C and then it told me it couldn’t read LLK, C or VM (refillable cart). So I shut if off and turned it on-same issue. Ive reset the ink levels, I swapped out the Epson C cart for the refillable one…nope. Now I have 3 refillable cart it cant read. And the one that started it all (LLK) I have already replaced the battery in. It has been fun. How can I fix this?
