    This is driving me nuts!!! I replaced the ink level sensor on the side of the ink holder, I have replaced the ink cart. with another one. I need to run a clean and can't because the y near end message won't let me. What sort of info is stored on the chip on the side of the actual ink cart? could it be that I am using a used ink cart. chip?

    Thanks. I still need help. now it says "ink end" even though there is a lot of ink left in the cart. I did find that the ink level sensor is broken. is there a way to bypass that thing? If I buy a new chip for the ink cart., will it see that it has ink available? This machine and I are not friends right now...

    Alright, after MUCH searching, I did find part of the answer from SIGHTLINE (thanks). The ink sensor breaks, this causes the machine to think that the ink is at end. The machine writes "ink at end" to the chip...permanently. So if I have this figured out, i need to replace the ink sensor and the cart. chip, and all should be good again right???

    UPDATE!!! It's fixed!!! I did replace the ink level sensor inside at the bottom of the ink slot (luckily it was on the yellow, so it was easy to access), but the machine still said "ink end". So I replaced the chip on the ink cart. and all is well. Apparently the information was correct in that once the sensor sends an "empty" signal, the machine writes to the chip that the cart. is empty...regardless of actual ink amount, and can not be erased. You have to change the chip. Sort of crumby, but the problem is fixed.
