摘要： An apparatus and method for delivery of sheet media to a printer includes a chassis, a drive motor, a media tray with elevatable pressure plate, a plurality of pick rollers situated opposite movable pinch rollers that come into contact with the pick rollers to form a roller assembly therebetween when in an extended position. A movable separator forms a throat between one of the pick rollers and the leading edge of the separator when it is in an extended position. A common transmission is used to simultaneously position the pinch rollers, separator, and the pressure plate. The apparatus also includes a media retarder for preventing multiple sheets of media from advancing through the apparatus at the same time. The method includes delaying the rotation of the pick rollers until a stack of media has been raised to press against the pick rollers, and the pinch rollers and separator are in an extended position. The pinch rollers and separator are retracted, and the transmission is disengaged from the pick rollers once the media sheet is delivered to a printer feed system.
摘要翻译：用于将片材介质输送到打印机的装置和方法包括底盘，驱动马达，具有可升高压力板的介质托盘，与可移动夹送辊相对的多个拾取辊，该拾取辊与拾取辊接触以形成辊当处于延伸位置时，它们之间的组件。当分离器处于伸出位置时，可动分离器在分离器之一和分离器的前缘之间形成喉部。常用的传动装置用于同时定位夹送辊，分离器和压板。该装置还包括用于防止多张介质同时前进通过设备的介质延迟器。该方法包括延迟拾取辊的旋转，直到一叠介质被升高以压靠拾取辊，并且夹送辊和分离器处于伸出位置。夹送辊和分离器缩回，并且一旦介质片被输送到打印机进给系统，变速器就从拾纸辊脱离。

摘要： A print media transport assembly for advancing a print media through a print zone includes a primary drive roller rotatably mounted on an entry side of the print zone and a pinch roller rotatably mounted opposite the primary drive roller. The primary drive roller and the pinch roller are adapted to contact the print media and the primary drive roller is adapted to advance the print media through the print zone. The print media transport assembly also includes a secondary drive roller rotatably mounted on an exit side of the print zone and a starwheel rotatably mounted opposite the secondary drive roller. The secondary drive roller is adapted to contact a first side of the print media and the starwheel is adapted to selectively contact a second side of the print media.

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： 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.
