摘要： To maintain a uniform spacing between the print media, such as paper or fabric, and an inkjet printhead having a large print swath, for instance about 25 millimeters (one inch) wide, a new media support system is provided for inkjet printing mechanisms, such as printers or plotters. The support system employs an endless belt (62) driven from the belt interior surface by a roller drive system that uniformly supports the printhead media under the reciprocating printhead (54, 56). The belt may be lined with anti-cockle ribs or it may be foraminous, with a vacuum applied thereunder to pull the media onto the belt. An ink drying system is included for heating the belt and thus the media to avoid ink bleed. A method is also provided for supporting and transporting a large sheet of print media through a printzone of an inkjet printing mechanism having such a large swath inkjet head.

摘要： In an inkjet printing apparatus an inkjet printhead ejects ink into a print-zone. A drive shaft, located upstream of the printhead, has a longitudinal axis, a first radius over a central length, and a second radius less than the first radius at a first recess and a second recess. Each recess is peripheral to the central length. A plurality of pinch devices stabilize the media against the drive shaft. A first guide and a second guide, spaced from the longitudinal axis, are aligned with and extend into the first recess and second recess.

摘要： A vacuum platen and method for use thereof in a printing device are disclosed. An apparatus embodiment includes a first surface having a plurality of first apertures therethrough, a labyrinth configured to include a plurality of passageways each of which is fluidly coupled to at least one of the first apertures, and a second surface having a plurality of second apertures therethrough each of which is fluidly coupled to the vacuum source and at least one of the passageways thereby establishing an airflow from the first apertures, through the passageways, and out the second apertures. The vacuum platen also includes at least one receptacle in each of the passageways, each receptacle configured to collect debris from the airflow as it travels through the labyrinth. A method embodiment includes distributing a vacuum hold-down force over the printzone, conducting an airflow causing the vacuum hold-down force from the printzone to the vacuum source, and collecting debris from the airflow by changing a direction of travel of the airflow as it is conducted from the printzone to the vacuum source. Further characteristics and features of the apparatus and method are disclosed herein.

摘要： A printer with a media transport has a rigid, air-transmissive platen. A movable air-transmissive flexible web overlies the platen and moves along a feed axis. A suction device communicates with the platen to draw air through the web and through the platen so that a sheet of media carried on the web is biased toward the platen. A manifold underlies the platen and has a number of separate chambers open to the platen, so that the suction device is connected to each of the chambers. A controller operates to selectably prevent communication between the suction device and at least some of the chambers.

摘要： A print media preheating method and apparatus uses heat, vacuum, and mechanisms for drying and flattening a sheet prior to ink-jet printing thereon. Pre-shrinking the media, driving out and substantially reducing inherent moisture content prior to depositing wet ink thereon provides greater flatness in the print-zone whereby ink-jet print quality is improved.

摘要： Anisotropic thermal conditioning of print media is provided for liquid colorant printing, such as in ink-jet hard copy apparatus, by establishing discrete temperature zones across a platen surface. Heat transfer mechanisms associated with individually selectable heater elements rapidly establish substantially uniform temperature profiles in each zone.

摘要： Non-black ink jet printheads are arranged in a printer carriage such that the printhead nozzle arrays are non-overlapping in the carriage swath direction. A fixer printhead is positioned such that the print medium is first advanced past the fixer printhead prior to reaching any of the other printheads. The printheads are selectively driven during each direction of a bi-directional carriage movement, and the print medium is incrementally advanced before each change in carriage movement direction. The order of laying down droplets of different colors is the same during the movement in each direction, thereby eliminating bi-directional hue shifting print artifacts.

摘要： An apparatus and method for delivery of sheet media to a printer includes a chassis, a drive motor, a media tray with elevatable pressure plate, a plurality of pick rollers situated opposite movable pinch rollers that come into contact with the pick rollers to form a roller assembly therebetween when in an extended position. A movable separator forms a throat between one of the pick rollers and the leading edge of the separator when it is in an extended position. A common transmission is used to simultaneously position the pinch rollers, separator, and the pressure plate. The apparatus also includes a media retarder for preventing multiple sheets of media from advancing through the apparatus at the same time. The method includes delaying the rotation of the pick rollers until a stack of media has been raised to press against the pick rollers, and the pinch rollers and separator are in an extended position. The pinch rollers and separator are retracted, and the transmission is disengaged from the pick rollers once the media sheet is delivered to a printer feed system.

摘要： Accurate advance of a media sheet is achieved by carrying the media sheet on a belt loop support. An upstream pinch roller holds the media sheet to the belt upstream of the print zone. A downstream pinch roller holds the media sheet to the belt downstream of the print zone. A guide shim extends along the media path from a position upstream of the upstream pinch roller, passed the upstream pinch roller under a printhead adjacent to the print zone. The location of a lead edge of the guide shim relative to the print zone determines the minimum bottom margin for the inkjet printing device. The guide shim presses the media sheet to the belt support and keeps the media sheet flat under the inkjet printhead as the printhead moves over the media sheet.

摘要： A media feed apparatus for a printer, with a motorized media pick mechanism and a media support plate movable toward and away from the pick element, so that a stack of media on the plate may be brought into contact with the pick mechanism. A lifter assembly is continuously movable between a first position and a second position, and has a cam surface supportably contacting the media support plate. A first cam surface portion contacts the support plate when the lifter assembly is in the first position, and a second cam surface portion contacts the support plate when the lifter assembly is in the second position. The support plate may have a protrusion over which the cam surface slides, and the cam may pivoted to provide a selectable lever arm, depending on the point of contact.
