摘要： A drive roll/idler roll nip release mechanism utilizes the motor used for the drive nip, coupled with one-way clutches, to power the nip release as a sheet is handed off to a downstream nip. A drive shaft is coupled to a first one-way clutch in one direction and an idler cam shaft is coupled to a second one-way clutch in the opposite direction. This allows the idler cam shaft to be driven only when the motor is reversed, and the drive shaft to be driven only when the motor is moving forward. The one-way clutch on the drive shaft allows the drive wheels to freewheel when the motor is reversed in order to engage the nip release. Thus, the nip release is activated while the drive nip continues to rotate in the direction of sheet motion.

摘要： An apparatus for reducing registration errors in a media handling device. The apparatus including an image-bearing member having sheets individually pass across the image-bearing member. Each sheet pass corresponds to one of a series of iterations between the image-bearing member and the sheets. The image-bearing member is operatively coupled to a controller for regulation motion of the image-bearing member. The controller receives input signals representing at least one measured disturbance. Each disturbance being defined by a pattern of image-bearing member movement away from and substantially returning to a reference state of motion. A repetition of the pattern being coincident with at least one of the iterations, wherein based on the measured disturbance, the reference state and an indication associated with when the pattern will repeat, a modified signal is generated for the actuator to adjust the image-bearing member motion in coordination with the indication.

摘要： An assembly includes two nip assemblies spaced apart along a first axis. Each nip assembly includes a driven wheel and an idler roller. The driven wheel rotatably supported about the first axis. The idler cooperates with the driven wheel to engage a sheet. The idler rotatably supported about a second axis. The second axis being selectively moveable relative to the first axis. The selective movement between a first and second orientation occurs while the sheet is moved along the transport path. In the first orientation the second axis extends parallel to the first axis. In the second orientation the second axis extends at an oblique angle to the first axis. The selective movement pivots about a third axis extending through a centerline common to both the driven wheel and the idler. The selective movement of one of the two nip assemblies being independent from the selective movement of the other.

摘要： According to aspects illustrated herein, a system, a printmaking device, and a method for pre-curling and registering media are provided herein. The system includes a media curler system and a deskew mechanism. The media curler system pre-curls at least one of lead edge and a trail edge of a sheet before delivery to a media hold-down transport. The deskew mechanism is coupled to the media curler system for pivoting the media curler system about a pivot axis to deskew the sheet. The pivot axis extends perpendicular to the media transport path. In operation, as the lead edge enters the pre-curling and registration system, the media curler system pre-curls the sheet towards the media hold-down transport. As the sheet is being pre-curled, the deskew mechanism pivots the media curler system about the pivot axis to correct any skew errors in the sheet.
