Abstract: A printer comprises at least one printhead having a plurality of inkjets, a dryer having an array of radiators including a plurality of rows of radiators and a plurality of columns of radiators, a media transport configured to move media past the at least one printhead and the dryer, and a controller operatively connected to the at least one printhead, the dryer, and the media transport. The controller is configured to activate selectively the radiators in the array of radiators to heat the portions of the surface of the media on which ink has been ejected. A method for operating the printer is also disclosed.

Abstract: A printing system includes a maintenance device that is configured to correspond to different configurations of a scalable printhead array. The printing system includes a first printhead array having a plurality of printheads and a pair of frames disposed in parallel and on opposite ends of the first printhead array. A first maintenance platform is mounted between the pair of frames and configured move from a first position at a first side of the first printhead array to a second position opposite faces of the printheads in the first printhead array. The first maintenance platform is configured to perform a maintenance operation on the plurality of printheads of the first printhead array when the platform is at the second position, and a first actuator is configured to move the first maintenance platform between the first position at the first side of the printhead array and the second position.

Abstract: A stapler apparatus includes a clamp positioned to receive and stack sheets from a printing device, a support plate comprising a groove directing the clamp along one path of multiple paths, the multiple paths alternately directing the clamp relatively closer to one of multiple staplers. A first biasing member applies a first force to the clamp toward a closed position, and a first extension applies a second force to the clamp toward an open position. A second biasing member applies a third force to the clamp toward the open position.

Abstract: Disclosed is a system for cleaning a print media sheet and, more particularly, for cleaning a specific portion of sheet that is less than the entire length of the sheet. A device moves a cleaning roller between standby, cleaning fluid receiving and cleaning positions. Timing of cleaning roller movement into the cleaning position is controlled to ensure proper positioning of the cleaning roller with respect to the sheet during cleaning. In the cleaning position, the cleaning roller rotates so as to clean only the specific portion. In the cleaning fluid receiving position, the cleaning roller rotates to receive, from a cleaning fluid dispenser, a predetermined amount of cleaning fluid. Optionally, a retractable shutter can be selectively retracted to expose an opening in a sheet transport path guard and, thereby allow the cleaning roller to move into the cleaning position.

Abstract: An apparatus, method and system for a feeding a sheet in a document reproduction machine. A feedbox is contained within a document reproduction machine. Within the feedbox, an elevator moves at least one sheet to the upper portion of the feedbox, to a stack height finger, for feeding the sheet into a feed device. At least one sensor, located at the upper portion of the feedbox, detects the location of the sheet. The location information is sent from the sensor to a data processing device. The data processing device sends information to an actuating device. The actuating device may cause one or more plungers to move through apertures in the elevator. The plungers will result in a substantially flat sheet. The sheet is then fed into the feed device.

Abstract: Disclosed are embodiments of a system and method for treating a printed flexible book cover prior to book binding. In the embodiments, a liquid (e.g., water or a water-oil solvent mixture) can be applied (e.g., by a liquid applicator, such as a spray nozzle, sponge, brush, etc.) to the spine portion only of the book cover so that it pools on the surface. After a predetermined amount of time, the liquid can be removed (e.g., by a liquid remover, such as a vacuum, blower, heater, etc.). Allowing the spine portion of the book cover to soak in the liquid for this predetermined amount of time ensures that the liquid saturates the spine portion. Saturating the spine portion of the book cover alters the surface structure and, thereby enhances adhesion of an adhesive material (e.g., glue or tape) during a subsequent book binding process even in the presence of fuser oil.

Abstract: A structure includes two plates (planar plates) joined at right angles to one another. The first plate has a non-round opening (first opening) and can include tabs extending from one end (a first end) of the first plate. The second plate has a round opening and/or a notch, depending upon implementation. The second plate can also include tab openings on opposite sides of the round opening, again depending upon implementation. If a notch is used, the notch is positioned along an edge of the second plate (positioned along a second end of the second plate). When the first and second plates are connected, the optional tabs are positioned within the optional tab openings, a first end of the first plate being connected to the second end of the second plate. A locking structure is positioned within the first opening, the round opening, and the notch (if used). The locking structure connects the first plate to the second plate.

Abstract: A device, method and program for automatically adjusting a paper curl of media in an imaging device are provided. The imaging device includes a decurler having two rollers defining a nip. A first roller has a substantially uncompressible surface, and a second roller has a substantially compressible surface. The first roller penetrates the second roller at the nip. The amount of curl of the media is adjusted at the nip by automatically adjusting the penetration of the second roller into the first roller. The amount of penetration of the second roller into the first roller is based on a set of factors and conditions. A penetration value based on the factors and conditions is used to adjust the position of the first roller and the second roller respective to each other, which in turn, will alter or reduce the media curl to a target curl.
