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： 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： 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： Apparatus and methods are disclosed herein for drying printing composition on a print medium. A disclosed apparatus for use in a printing device configured to dispose printing composition on a print medium includes a blower configured to provide an airflow and a heater configured to heat the airflow. The apparatus also includes a duct coupled to the blower and configured to conduct the heated airflow by the print medium to help dry the printing composition on the print medium and a vacuum box coupled to the heated airflow and configured to provide a hold-down force on the print medium adjacent the vacuum box. Further characteristics and features of the present invention are disclosed herein, as are exemplary alternative embodiments. This abstract is not to be used in the interpretation of any of the claims.
