    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: An ink-jet apparatus employs a platen having an array of vacuum ports that are each filtered. The filter is constructed to provide restricted-airflow rates which remain uniform when the platen is either fully covered or partially uncovered. The filter mechanism provides both airflow restrictions such that ink drop flight trajectories in the printing zone are unaffected, acoustic dampening of the vacuum pump is provided, and vacuum pressure is kept relatively high proximate the print media edges.

    摘要: An ink-jet apparatus is disclosed having a vacuum type print media transport subsystem for moving the print media through a printing zone. A transport belt is provided with an array of perforations such that vacuum flow is restricted. The perforations only pass vacuum induced airflow through the belt when over vacuum ported platen regions.

    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.
