Digital BW, The Print

Hassan:

I'd say you are RIGHT ON topic. This chip thing is way crazier than I ever imagined. One of these ink supply houses must have a good handle on the various printer/cartridge/chip/revision issues. 

You will probably have to purchase a new set of cartridges. I'll throw in a good word for inksupply.com. Try reaching out to their support department and ask them the same question you posed here.
