An inkjet printer includes a print medium cartridge arranged to store a print medium roll. The print medium roll includes a former carrying a wound length of a print medium. A platen supports the print medium during feeding from the roll. An inkjet printhead assembly is arranged in register with the platen and includes an inkjet printhead having a plurality of micro-electromechanical inkjet nozzles which can print onto the print medium supported by the platen. A print medium feed arrangement is arranged to feed the print medium from the roll and between the platen and the inkjet printhead assembly.

An inkjet printer has a print medium cartridge configured to store a print medium roll. The print medium roll has a former carrying a length of print medium and an ink supply core which can be received within the former. An inkjet printhead prints onto the print medium and an ink transmission channel structure connected between the ink supply core and the inkjet printhead assembly to transport ink there-between. The print medium is drawn from the roll by a print medium feed arrangement that feeds the print medium past the inkjet printhead during printing.

A method of fabricating a plurality of inkjet nozzles on a substrate. The method comprises the steps of: (a) providing a substrate having a plurality of trenches corresponding to ink inlets; (b) depositing sacrificial material so as fill the trenches and form a scaffold on the substrate; (c) defining openings in the sacrificial material; (d) depositing roof material over the sacrificial material to form nozzle chambers and filter structures simultaneously; (e) etching nozzle apertures through the roof material; and (f) removing the sacrificial material.

A nozzle arrangement for an inkjet printhead comprises a substrate defining an ink supply channel; a nozzle chamber structure mounted on the substrate, the nozzle chamber structure defining a nozzle chamber in fluid communication with the ink supply channel and a nozzle rim defining an ink ejection port in fluid communication with the nozzle chamber, the nozzle chamber structure further defining a slot in a first side wall thereof; a post, provided outside of the nozzle chamber, extending from the substrate; and a thermal actuator mechanism comprising an actuator arm extending from the post and through the slot to terminate freely in the nozzle chamber. The actuator arm comprises a slot protection barrier extending substantially orthogonally therefrom, the slot protection barrier positioned adjacent to the first side wall and spaced therefrom to define an ink holding area between the slot protection barrier and the first side wall.
摘要:
An ink supply unit for a pagewidth printer having a printer controller configured to operatively control a printhead integrated circuit. The supply unit includes a housing defining a number of external protuberances for positioning tape automated bonded film, and a baffle unit positioned inside the housing to define three ink storage chambers. The unit also includes an ink manifold arranged in fluid communication with the ink storage chambers, a printhead integrated circuit arranged in fluid communication with the ink manifold, and a cover unit operatively fast with the housing. The cover unit sandwiches tape automated bonded film to the housing to arrange the printhead integrated circuit in electrical communication with the printer controller.

An ink refill unit is provided for refilling a printer ink cartridge unit. The ink refill unit includes a base assembly which houses internal ink refilling components and defines a plurality of outlets for docking with the cartridge unit. Each outlet corresponds to a respective type of ink with only one of the outlets working. The ink refilling components include a syringe assembly coupled in fluid communication with the working outlet. A lid assembly fits onto the base assembly to cover the ink refilling components.
摘要:
A printing fluid supply device for a printhead, that has a printing fluid reservoir containing a quantity of printing fluid, a porous body having a plurality of individual channels arranged in an array for supplying the printhead with printing fluid under capillary action and a fluid trapping layer between the porous body and the printing fluid reservoir for trapping the printing fluid from the printing fluid reservoir such that it can be extracted by the plurality of individual channels and drawn to the printhead.
摘要:
A pagewidth printhead assembly for an inkjet printer that has a body portion for receiving ink from one or more ink sources and having one or more channels formed therein for distributing the ink substantially along the length of the printhead assembly, and one or more integrated circuits extending substantially the length of the printhead assembly. The or each integrated circuit has a plurality of nozzles, each being arranged in use to deliver the ink onto passing print media. The assembly also has an ink distribution member upon which the or each integrated circuit is fixed and which distributes the ink from the body portion to each of the integrated circuits. The ink distribution member is a unitary element having a plurality of conduits formed therethrough. Each of the conduits having an inlet which receives ink from one of the channels of the body portion and an outlet which delivers the ink to a predetermined number of nozzles of the one or more integrated circuits.
