摘要： A printing mechanism comprises a print engine that prints an image on a first side of a photographic print media, a laminator that laminates the first side of said photographic print media having said image printed thereon, and a duplexer that returns said photographic print media to said print engine for printing on a second side of said photographic print media.

摘要： The invented printer includes a paper drive and mechanisms which hold paper in proper alignment in the drive. Specifically, it includes a pressure plate capable of bringing a sheet of paper into contact with a drive roller so that the paper is properly aligned, a wrapper which keeps paper in proper contact with the drive roller, a media edge contactor that presses against paper, a carriage guide support which helps to insure proper alignment of the paper during printing, and a back-out restraint to prevent paper from backing out of the printer.

摘要： A difference in feed roller diameter from one printer to another causes a media to advance by a different amount for a given rotation of a drive shaft to which the feed roller is coupled. Such variation in advance distance is a linefeed error. Mean linefeed error is determined and corrected by printing a test plot having several areas. Each area is formed of the same image pattern, but is printed at a different linefeed error adjustment to compensate for mean linefeed error. The different adjustments are prescribed and span a typical compensation range for a given print engine model. The different adjustment factors cause banding to occur in some areas. The user picks one of the test pattern areas which has the highest print quality (i.e., least or no banding). The linefeed adjustment factor corresponding to such area is used for normal printing.
摘要翻译： 进料辊直径从一台打印机到另一台打印机之间的差异导致介质在进给辊联接到的驱动轴的给定旋转中前进不同的量。 预先距离的这种变化是换行错误。 通过打印具有几个区域的测试图来确定和校正平均换行错误。 每个区域由相同的图像图案形成，但以不同的换行错误调整打印以补偿平均换行错误。 对于给定的打印引擎模型，规定了不同的调整并跨越了典型的补偿范围。 不同的调整因素导致一些地区发生捆绑。 用户选择具有最高打印质量的测试图案区域之一（即，最少或不包带）。 与该区域对应的换行调整系数用于正常打印。

摘要： In an inkjet printing apparatus an inkjet printhead has a plurality of inkjet nozzles which eject ink onto media located within a print-zone. A drive shaft is located upstream of the printhead and is incrementally rotated to advance the media. The drive shaft 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 said recess being peripheral to the central length. A plurality of pinch devices stabilize the media against the drive shaft. A first guide is aligned with the first recess and is spaced from an axis of the drive shaft by a first distance which is less than the first radius. A second guide is aligned with the second recess and is spaced from the axis by a second distance less than the first radius.

摘要： A holddown for a hard copy device comprises a member having a surface and plural vacuum zones. Each of the vacuum zones defines a cavity in the surface having at least one port therethrough, and each cavity is defined by a sidewall circumscribing the cavity. At least one of the cavities has sidewall with a first section at a first height relative to the surface and a second section at a second height relative to the surface.

摘要： Apparatus for advancing media through a hardcopy device includes a cylindrical guide wheel having a first radius mounted on a shaft having an axis transverse to a media feed path axis. A guide surface is spaced apart from the guide wheel and defines a media feed path between the guide wheel and the guide surface. A drive wheel having an extended portion that is concentric with the guide wheel, and which has a greater radius than the first radius is fixed to the shaft. A pinch roller communicates with the media feed path.
