I purchased three carts LT BLK, Green, Cyan. I first installed the LT BLK cart and it was not recognized, I tried many different corrective measures and none worked. I called and it was decided a new cart would be sent to me. That one did not work either. I decided to change the green and Cyan carts to see what would happen. They worked fine but the LT BLK still did not work. I ordered a Epson LT BLK cart and replaced your cart with it and it worked fine only now the Green and Cyan carts are not recognized. I kept trying different corrective measures and sometimes the Green cart would be recognized, but never the Cyan.
I have only used Epson 350ml carts and yours are 800ml.
I read all the FAQ’s and forum treads and tried there suggestions except changing chips or resetting chips. I do not have a chip re-setter.
What should I try next?
