I have an LK cartridge “not recognized” message. I’ve tried three new chips fresh from Inkjetmall on the cartridge with no luck. I’ve tried disconnecting the printer - no change. In the middle of all this I then got an MK cartridge not recognized message! Replaced it and the message went, only to come back on when trying another replacement chip on the LK!!
I can’t fathom this at all. A visual inspection doesn’t show any obvious defect with the pins that the LK cartridge connects to. I can’t help but think (and groan) that this means there’s something more seriously wrong with the printer. The only thing I would add is that I’ve just completed a clean of the capping station and print head (as in Dana’s video), as I hadn’t done it for a while. I did this after the first message I got about the LK cartridge whilst waiting for the new LK chips to arrive.
