Claim:
An inkjet printer cartridge comprising: a pagewidth printhead integrated circuit having a plurality of micro-electromechanical nozzle arrangements; a rotor element rotatable, in use, between a blot position where the element blots the printhead integrated circuit, a seal position where the element seals the nozzle arrangements, and a platen position where the element supports and positions a printing medium proximate the printhead integrated circuit; an air distribution channel configured to deliver air evenly along a length of the printhead, communicable with a pressurized air supply; a plurality of reservoirs for discretely storing printing fluids for supply to the printhead integrated circuit; a refill port arranged in fluid communication with printing fluid conduits each leading to a respective reservoir, the port facilitating refilling of the reservoirs from a refill cartridge; and a power and data interface for interfacing the printer cartridge with a controller board for controlling operation of the printhead integrated circuit and the rotor element.
