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 novel ink-jet printer (10) is provided. The print provides both paper supply tray (12) and paper collection tray (18) in the front (14) of the printer for ease of paper handling and reduced footprint. The paper collection tray is provided with a pair of opposed output rails (22) which support a sheet of paper (16c) during printing to permit ink on a sheet of paper (16b) previously printed to dry. A paper handling mechanism is provided which eliminates a sheet pickup motor and associated elements. The paper handling mechanism is configured to pick off a sheet of paper from a stack of input paper, bring it around paper drive rollers (24) onto a platen (26), where the printing operation, employing a printhead cartridge (32), occurs. The printer further includes a service station (230) for clearing clogged nozzles in the printhead (33) and removing bubbles therefrom, for covering the nozzles with a protective cap (266), and for wiping contaminants off the nozzles. Reference pads (200) are provided for aligning and securing the printing cartridge in a carriage (35). The carriage is associated with a carriage guide (27), to which the carriage and print medium are referenced. The resulting printer is easy to manufacture, has reduced complexity by eliminating components in the paper drive mechanism and is lower in cost.

摘要： An active paper drop mechanism (20) for ink-jet printers is provided. The mechanism comprises a pair of opposed, movable rail members (22) associated with opposed walls (14) of a horizontal-disposed output collection tray (12) for receiving sheets (10) of printed media.In particular, each rail member is provided with return spring (26) that act to maintain the rails in a closed position. In that position, the rails support a sheet of the print medium during the printing operation, thus giving the ink on the previously printed-on sheet (10') time to dry.The rails are provided with a wing member (32) and are pivotally secured (38) in the floor of the output tray, with the pivot point spaced inwardly from the wing member. Downward pressure against the wing member thus causes the rail to rotate outward from its closed position, into a recess (24) provided in the side of the output tray. This provides sufficient clearance for the sheet to drop into the output stack. Upon release of the downward pressure, the spring causes the rail member to return to its original closed position.

摘要： A paper handling system is provided which allows for controlled passage of a pivot between a normally biased initial position and a task-performing position. The pivot includes a sheet-directing member and a track which is fixed relative to the sheet-directing member and is movable to the task-performing position in opposition to pivot bias. A follower, which is configured for selected travel along the track, selectively applies a force against the track in opposition to biased sheet-directing member movement. A processor-controlled printhead carriage is used to trigger and then to regulate pivot rotation.

摘要： An improved printer paper stack-handling device is described. In its preferred embodiment, the stack-handling device includes a pivot member with a downwardly inclining paper top-of-stack contact surface. The device also includes a force mechanism, e.g. a leaf spring, to pivot the member into contact with the top sheet of a paper stack. The spring and the pivot member's inclined contact surface produce a variable top sheet bias for corresponding variable paper stack heights, to properly laterally align the top sheet against a fixed, opposing guide rail, for feeding to a printer input port.
