I’m sorry to hear you are having a hard time getting your M cartridge to behave, it sounds like it came with a defective control chip. I have put a SO together for a replacement and it will ship out in the mail tomorrow, please let me know if it solves your problem.
Thanks for sending the Magenta chip. That problem is resolved!
However, I just inserted the Lt Cyan cartridge. After seeing an error, I examined the chip and saw it only had two pins, not three. Rats.
Would you send me a Light cyan replacement chip also?
I checked the others I havent installed yet. They seem to have all their pins.
Looking forward to happily printing…
