The cartridge is a 300ml Cyan for my 7890.
I bought a chip a couple of weeks ago to replace the old chip that kept failing after each print. I would have to open the ink door eject the Cyan cart and re install it till the new one came in, the printer would recognize it again. Once the new chip came in I replaced the old one and inserted the cart. This new chip was showing the same problem. I figured I might have been sent a bad Cyan chip. I received a new one a couple of days ago and again, same problem.
Any help would be much appreciated. Just some info, this was happening with the Cyan chip on my old 44" 9890 as well but it was spotted, only happen once twice a month earlier this year.
talk to you soon.
