I have this problem with my ink reading near end when I insert to my 1st yellow slot...at first I thought it was the chip, but swap it to 2nd yellow slot which was 5 remaining and as I swapped to 1st slot it read near end on the cartridge that had 5 remaining and now the 2nd slot still reads near end on the cartridge that came from the 1st slot. could it be my ink sensor assemly is bad..I think if I keep putting new cartridges it will write near end on all cartridges I insert which will make my chips useless. How can I fix this issue?
