Abstract: An inkjet printer that has a printer body, a printhead cartridge for installation in the printer body, the printhead cartridge having a pagewidth inkjet printhead structure with an array of nozzles, a plurality of ink cartridges for supplying ink, each of the ink cartridges having a docking face for engagement with a complementary face partially provided by the printhead cartridge and partially provided by the printer body and, a docking frame with a plurality of resilient connectors form part of fluid paths from the ink cartridges. Longitudinal expansion and contraction of the pagewidth printhead structure relative to the docking frame is accommodated by the resilient connectors.

Abstract: A printhead for an inkjet printer that has an elongate array of nozzles (68) for ejecting ink and ink conduits for supplying the array of nozzles with ink. The ink conduits extend adjacent the elongate array and have a plurality of pulse dampers individually in fluid communication with the ink conduits, each containing a volume of gas for compression by pressure pulses in the ink conduits, distributed along the length of the elongate array. A pressure pulse moving through an elongate printheads, such as a pagewidth printhead, can be damped at any point in the ink flow line. However, the pulse will cause nozzle flooding as it passes the nozzles in the printhead integrated circuit, regardless of whether it is subsequently dissipated at the damper. By incorporating a number of pulse dampers into the ink supply conduits immediately next to the nozzle array, any pressure spikes are damped at the site where they would otherwise cause detrimental flooding.

Abstract: Provided is a print cradle assembly for a printhead cartridge. The cradle assembly includes a docking bay molding and a media feed drive assembly positioned on the docking bay molding and configured to feed media through the assembly. The cradle assembly also includes a printed circuit board (PCB) with a printer controller for controlling the media feed drive assembly and operation of the cartridge, as well as a heatshield mounted to the PCB for shielding the printer controller from electromagnetic interference (EMI) and user contact with the PCB.

The LCS is provided with rules and procedures for accepting and transmitting content data.

Abstract: An inkjet printer comprising: a printer body and a replaceable printhead cartridge, the printhead cartridge having a casing that supports a pagewidth printhead; the printer body having a cradle for holding the printhead cartridge in an operative position such that the pagewidth printhead is adjacent a paper path defined by the printer body; wherein, during insertion, the cradle and the casing interact to form an over centre mechanism whereby, the printhead cartridge rotates against a bias prior until reaching a balance point, after which it is biased to rotate into the operative position.

Abstract: An inkjet printer comprising: a printer body; a printhead cartridge for installation in the printer body; an ink cartridge containing a supply of ink, the ink cartridge having a docking face for engagement with a complementary face to supply the printhead cartridge with ink; wherein, the complementary face is partially provided by the printhead cartridge and partially provided by the printer body.

Abstract: An inkjet printer comprising: a printhead cartridge with a printhead and a maintenance station for engaging the printhead when not in use; a printer body with a cradle for receiving the cartridge, and a maintenance station drive shaft for detachably engaging the maintenance station upon insertion of the printhead cartridge into the cradle, the maintenance station drive shaft having an engagement formation for engaging a complementary formation in the maintenance station; such that, when engaging the complementary formation, the engagement formation has limited axial displacement and limited transverse displacement.

Abstract: A capping mechanism is disclosed for a pagewidth printhead assembly having a pagewidth printhead and a plurality of nozzles located along the printhead for delivering ink onto print media as it is transported past the printhead. The capping mechanism comprises: i) a capping member having a length corresponding substantially to that of the printhead, and ii) an actuating mechanism arranged to effect linear transitioning of the capping member from a non-capping first position to a second position at which the capping member is located in nozzle capping engagement with the printhead. The capping mechanism is also disclosed in relation to a printhead assembly having two pagewidth printheads, and further disclosures are made in respect of an inkjet printer incorporating the capping mechanism and a method of capping a pagewidth printhead.
