Abstract
An air pressurization system is incorporated as part of a replaceable auxiliary ink supply for an inkjet printer. The auxiliary ink-supply cartridge includes a pressurized container having air, ink and electrical-signal connections. The air pressure applied to the auxiliary ink supply is monitored to maintain it in a predetermined range in accordance with a start-up sequence, and operational sequence, a waiting time, and a close-down sequence.
