    摘要: An inkjet printing device comprises a platen on which a printing zone is defined, a carriage, onto which at least a printhead is mounted, slidable along the printing zone near the platen, a service station, located in a service zone separated from the printing zone, a housing protecting and enclosing the printing zone and the servicing zone, and a device, for example a fan, for producing an air flow within the housing. A substantially constant air path is defined within the housing of the device through which the air flow is allowed to pass during its operation. A method for reducing ink aerosol in such a device, during its operation, comprises the following steps: producing an air flow within the housing, and forcing the air flow to pass through a substantially constant air path defined within the housing.

    摘要: An ink-jet printer having improved print quality and full color printing capability on plain paper media. To accommodate placement of both input and output media trays on the same side of the printer housing for operator convenience, a paper path with a direction reversal is employed. A paper preconditioning preheater with a curved surface and a multi-purpose paper path component accomplish the direction reversal. The paper path component is a unitary component which employs curved ribs to reduce the contact area with the medium and reduce static charge buildup, and has slots formed therein to release water vapor given off by the medium when preheated. The component permits paper to be loaded manually via a second manual feed path, through a housing, and upon opening a rear access door in the housing, such component is easily removable to facilitate operator access to the paper path and electrical components.

    摘要: A printer architecture structure in which a flexible external case is used to compress and sandwich internal printer structure comprised of a rigid metal base and printer chassis structure by nominally compressing resilient pads between the chassis structure and case top and side walls. Additional resilient pads between the base and chassis structure are ordinarily nominally uncompressed by the flexible case except during application of shock loads during shipment or vibrations during printer operation. The construction minimizes transmission of externally applied shock loads through the internal components of the system and assists in containing vibrations and noise generated during printer operation interiorly of the case. The relatively rigid base comprises a metal enclosure for RF shielding of the electronic components.

    摘要: Two printing-medium guide systems restrain the medium. One is in an area upstream (along the direction of medium advance) from the pen, and extending laterally across the width of the medium except in one or more regions laterally near the engagement of a print-medium advancing device. The other guide system is disposed laterally from the pen, and extends laterally across the medium only in one or more regions laterally near the engagement of the advancing device. Preferably these "one or more regions" are only near the lateral edges of the medium--so that (1) the first guide system restrains the medium over an area that stops short (ideally about 11/2 centimeter short) of the lateral edges; and (2) the second guide system is bifurcated, disposed laterally in two directions from the pen, and restrains the medium across only the lateral edges of the medium (most preferably in a strip whose width is a few millimeters, ideally 3 mm). Preferably a human-actuable control selects a print-medium width, and shifts at least one bifurcation of the second guide system. A tensioning system, longitudinally beyond the marking head from the medium advancing device, and generally aligned laterally with that device, tensions the medium away from the advancing device to hold the medium taut at the pen. Preferably the advancing and tensioning devices are very closely spaced upstream and downstream, respectively, from the pen zone. When tensioned, the medium moves a normal distance through the apparatus at each operation of the advancing device; but after a trailing edge of the medium passes the advancing device (so that the medium is advanced only by the tensioner and no longer tensioned), the advance distance is decreased (preferably by about half).

    摘要: An ink-jet printer having improved print quality and full color printing capability on plain paper media. To accommodate placement of both input and output media trays on the same side of the printer housing for operator convenience, a paper path with a direction reversal is employed. A paper preconditioning preheater with a curved surface and a multi-purpose paper path component accomplish the direction reversal. The printer further includes a manual feed path for guiding a manually fed sheet or envelope from a manual feed inlet slot at the top, rear corner of the printer to a path converging location with the primary feed path. The preheater includes a heating portion disposed along the primary path between the path converging location and the-print area, to provide the capability of preheating media fed either from the input tray or the manual feed slot.

    摘要: A piezoelectrically driven ink jet print head for ejecting ink droplets from an ink supply within the print head through a discharge channel onto a writing surface includes a shutter mechanism that may be electromechanically controlled during selected periods of time to seal the ink supply within the print head from the atmosphere and from a high speed laminar flow of air used to accelerate ejected ink droplets.
