Abstract: A printing assistance apparatus for a media width printhead, the apparatus having: an elongate platen having a surface for supporting media across the media width during printing on the media by fluid ejection nozzles of the printhead; and a wick element positioned within the platen for wicking fluid ejected by the nozzles from the supporting surface, the wick element having an elongate body positioned within the platen and a plurality of pads projecting from the body along the longitudinal length body toward the printhead, the pads being separated by notches.

Abstract: A wiping device for maintaining a printhead is provided having a body supported within a maintenance unit of the printer, a porous roller rotatably mounted to the body, and a mechanism mounted to the body for rotating the porous roller. The body is configured to be lifted from the maintenance unit so as bring the porous roller into contact with a printhead of the printer. The mechanism rotates the porous roller so that the porous roller rotates against the printhead wiping the printhead clean. The mechanism is connectable to a power supply of the printer and is configured to be lifted from the maintenance unit together with the body while connected to the power supply.

Abstract: Method of shaping media for printing by a media width printhead, the method having transporting media into a print zone defined by a plurality of fluid ejection nozzles of the printhead with input rollers at an angle to a plane parallel with the print zone; transporting media out of the print zone with output rollers at an angle to said parallel plane; and supporting and shaping the media as the media is transported through the print zone with an elongate platen, the platen having a series of upstream ribs disposed upstream of the print zone with respect to the media transport direction and a series of downstream ribs disposed downstream of the print zone with respect to the media transport direction, wherein the ribs are configured so that the transported media is in contact with the ribs in the print zone and adopts a constrained curved path past the nozzles.

Abstract: A system for guiding media past a media width printhead. The system includes: a media width printhead having printhead ICs defining respective print zones; input and output rollers; and an elongate platen for guiding the media as the media is transported through the print zone. The platen has a series of upstream ribs and downstream ribs configured for contacting the media and guiding the media through the print zone. The platen has an aperture such that each printhead IC of the printhead is positioned opposite the aperture, and the print media is suspended between the upstream and downstream ribs across an entire width of the print zone of each printhead IC.

Abstract: A maintenance system for a printhead is provided having a support frame, a wiper module supported by the support frame, a lift mechanism for lifting the wiper module from the support frame, and a rotation mechanism.
