This is not a hindering issue, but I am mystified enough to wonder if there is an explanation.
The chip on my light magenta cartridge registers as going down very quickly. When it gets near empty I remove it and and find that is is still quite full. I reset the chip and it register full but then goes to empty quickly again even though it still has lots of ink.
Other chips operate correctly.
These are refillable cartridges I purchased from InkJetMall.
