摘要： A vacuum holddown device for a hardcopy apparatus, comprising a printing platen with a pattern of through holes and an underlying vacuum chamber, further comprises a member located therebetween and having a substantially similar pattern of through holes, the member being moveable to align the pattern of holes or not so as to respectively interconnect or disconnect the holes in the printing platen and the vacuum chamber. The member may itself define a secondary chamber with which the holes in the printing platen are in communication when not in communication with the vacuum chamber.
摘要翻译：一种用于硬拷贝装置的真空压紧装置，包括具有通孔图案和下面的真空室的印刷台板，还包括位于其间并具有基本相似的通孔图案的构件，所述构件可移动以对准图案孔，以便分别互连或断开印刷台板和真空室中的孔。该构件本身可以限定一个辅助室，当不与真空室连通时，打印压板中的孔与该室连通。

摘要： A media outputting device for a hardcopy apparatus includes a media source and at least one roller having an outer surface with a contact region for engaging media, where the roller is rotatable for outputting the media. The media outputting device also includes a negative pressure mechanism for creating a negative pressure distribution on the contact region where at least one portion of the contact region that is farther from the media source has a greater negative pressure than at least one portion of the contact region that is closer to the media source.

摘要： A hardcopy apparatus includes a media holddown unit, having a platen, and a vacuum source for generating negative pressure on a medium positioned on said platen to keep it flat on said platen. The unit includes at least two vacuum chambers, both in air communication with the vacuum source. Each of the vacuum chambers can apply a negative pressure to a different portion of the medium positioned on a corresponding different region of the platen. A method for holding down a medium when placed on said platen. First the vacuum source is placed into independent air communication with a number of distinct regions of the platen, then the medium is positioned to cover one or more regions of the platen, and finally a negative pressure is applied to the back of the medium via the independent air communication.
摘要翻译：硬拷贝装置包括具有压板的介质压紧单元和用于在定位在所述压板上的介质上产生负压以将其平坦地保持在所述压板上的真空源。该单元包括至少两个与真空源空气连通的真空室。每个真空室可以对位于压板的相应不同区域上的介质的不同部分施加负压。一种当放置在所述压板上时压住介质的方法。首先，将真空源放置成与压板的多个不同区域的独立空气连通，然后将介质定位成覆盖压板的一个或多个区域，最后将负压经由介质的背面施加到介质的背面独立空中交通。
