    Abstract: An inkjet printer includes: a printhead having a first port and a second port; an ink container for supplying ink to the printhead, the ink container comprising a supply port and a return port; a first ink conduit interconnecting the supply port and the first port; a second ink conduit interconnecting the return port and the second port; and a pump configured for pumping ink from the supply port to the return port. The second ink conduit has a smaller internal cross-sectional area than the first ink conduit for providing a faster flow speed of ink in the second ink conduit relative to the first ink conduit when the pump is actuated.

    Abstract: An inkjet printhead with planar thermal actuators (12), contacts (28) directly deposited onto the CMOS electrodes and suspended heater element (29), which avoids hot spots caused by vertical or inclined surfaces so that the contacts (28) can be much smaller structures without unacceptable increases in resistive losses. Low resistive losses preserves the efficient operation of a suspended heater element (29) and the small contact size is convenient for close nozzle packing on the printhead.

    Abstract: A printer cartridge for an inkjet printer including a printing fluid storage means (28, 30, 32, 34) and a pagewidth printhead (52) in communication with said printing fluid storage means. The inkjet printer including a cradle unit having a body complementary to the removable printer cartridge; a data connection point fast with the body for receiving data signals defining images for printing from an external data source; and aprocessing means coupled to the data connection point and arranged to operate the pagewidth printhead in response to the data signals to print said images.

    Abstract: A printer is disclosed which comprises a pagewidth printhead assembly having a pagewidth printhead (51) and a plurality of nozzles located along the printhead for delivering ink onto print media as it is transported past the printhead and a capping mechanism having a capping member (82) having a length corresponding substantially to that of the printhead, a first actuating mechanism (84) arranged to move the printhead in an arcuate direction from a first to a second position (figure 9B) and a second actuating mechanism (85) arranged to move the capping member in a direction normal to the printhead (figure 9C) to effect nozzle capping engagement of the printhead when the printhead is in the second position.

    Abstract: A printhead maintenance assembly (10) for maintaining a printhead (1) in an operable condition is provided. The maintenance assembly (10) comprises (i) a printhead assembly (11) comprising a printhead (1) having an ink ejection face (18) and a film guide (21) sealingly bonded to the face (18), the film guide (21) being positioned to guide a film (20) through a transfer zone (22) defined by a plane spaced apart from the face (18); and (ii) an ink transport assembly (12) comprising a film (20) and a transport mechanism for feeding the film (20) through the transfer zone (22) and away from the printhead (11). In use, the film (20) sealingly contacts with the film guide (21) thereby forming a cavity (23) defined at least partially by the film (20), the film guide (21) and the face (18).
