I own an HP 5850 inktank printer that stats show I've printed 28k pages and around 4k scans. You just buy a bottle and pour it in the reservoir. No chips, no updates. No firmware. It does have the cleaning head issue that jams and says you only can do it 3 times which I suspect is based on number of pages printed and not actual health of head but not sure.
