A multi-color ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.

Embodiments of an ink tank are provided, which comprise an ink tank housing, at least one air vent disposed on the housing, and at least one RFID tag disposed on the housing, wherein the at lest one RFID tag is operable to communicate with an RFID reader. The ink tank further comprises a sealing component operable to close the air vent. The sealing component has conductivity operable to interfere with the communication of the RFID tag and the RFID reader such that the RFID tag is incapable of communicating with the RFID reader when the vent is closed.

RFID detection of air vent condition in inkjet printer supplies

Methods and apparatuses for compensating for changes in delivery pressure and protection of a printhead against increased ink flow resistance caused by air trapped in the felt or foam are described. In an exemplary embodiment, ink ejection flow rates are adjusted to keep delivery pressures safely at or below the maximum sustainable delivery pressure required to protect a micro-fluid ejection device of a printhead assembly.
