    摘要： A printhead is provided having an elongate support having a plurality of internal webs protruding from a base section to define a plurality of parallel fluid supply channels, a shim supported by the support and defining a plurality of rows of openings through which fluid from respective supply channels is supplied, and a plurality of elongate printhead modules supported serially on the shim. Each module defines a plurality of fluid supply passages through which fluid passes to fluid ejection nozzles from respective rows of the openings. Either end of each module defines complementary formations such that adjacent modules nest together.

    摘要： An inkjet printer includes a printhead for printing onto a media substrate, the printhead defining a plurality of nozzles from which ink is expelled; an ink tank provided upstream of the printhead; a sump provided downstream of the printhead for collecting unused ink from the printhead, the sump having a lower portion for holding the unused ink and an upper portion defining a headspace of air above the unused ink; a first fluid conduit extending between the printhead and the sump for communicating the unused ink from the printhead to the sump, the first fluid conduit connecting the sump to a position in the printhead upstream of the plurality of nozzles; and a pump connected to the sump, the pump for drawing air from the headspace of the sump into atmosphere and effecting a negative pressure in the printhead upstream of the nozzles. Communication of ink from the ink tank to the printhead is effected by the negative pressure generated by the drawing of air from the headspace of the sump.

    摘要： A feed mechanism for a wide format printer is provided having a supply spool for supplying media web to a printhead, a take-up spool for receiving the web after printing, a take-up motor connected to the take-up spool, a take-up control system for controlling the take-up motor torque, a drive roller system positioned between the supply and take-up spools, a drive motor connected to the drive roller system, and a braking motor connected to the supply spool for generating tension in the web between the supply spool and the drive roller system. The take-up, drive and braking motors are separate motors and are separately connected to the take-up spool, drive roller system and supply spool, respectively. The web fed from the drive roller system to the take-up spool is maintained under substantially constant tension by regulating the torque of the take-up motor using the take-up control system.

    摘要： An inkjet printhead having a wafer substrate defining a planar support surface is disclosed. Ink chambers are includes adjacent the planar support surface of the wafer substrate. The ink chambers are defined by sidewalls extending between a nozzle plate and the wafer substrate. One of the sidewalls of each chamber has an opening to allow ink to refill the chamber. An ink conduit is included between the nozzle plate and wafer substrate. The ink conduit is in fluid communication with the openings of the ink chambers. Ink inlets defined in the wafer substrate are also provided, the ink conduits receiving ink to supply to the ink chambers from at least one of the ink inlets. Each of the ink inlets has an ink permeable trap and a vent sized so that the surface tension of an ink meniscus across the vent prevents ink leakage. During use the ink permeable trap directs gas bubbles to the vent where the gas bubbles vent to atmosphere.
