摘要： A system for automatically releasing selected plural sheet feeding nip sets spaced along a print media sheet feeding path of a printer, wherein the idler rollers are rotatably mounted on common idler shafts and a selectable partial rotation system driven by a single low cost motor is flexibly connected to those plural idler shafts to partially rotate eccentric lift cams on each idler shaft into the underlying surface as to lift the idler shaft and thereby move the idler rollers away from their normally mating sheet feed rollers to release all the sheet feeding nips, enabling sheet deskew, inversion, acceleration, deceleration, or sheet jam clearance in that selected area of the sheet feeding path.

摘要： A sheet registration system, especially for printers, with a lower cost and lower mass-movement system for both sheet deskewing and transverse registration repositioning of the sheets in the same integral system, especially for higher speed printing. Only one main drive motor can drive both of the two spaced apart sheet feeding nips, together with a lower power, lower mass, deskewing differential drive system for providing the relative differential angular movement of the two spaced sheet feeding nips to achieve the desired amount of sheet deskewing movement, without interrupting the forward feeding movement of the sheet. Also disclosed are extensive further reductions in the component mass of the lateral translation movement for lateral sheet registration.

摘要： A printing system and method using alternating control modes for one or more, but not all, sheet transport devices in order to avoid contention. In a printer having first, second and third sheet transport devices in series (e.g., registration, image transfer and image fixing devices), the second device can always operate in a velocity control mode. However, the first and/or third devices can alternate between velocity and torque control modes. For example, the first device can operate in a torque control mode, when a sheet is concurrently engaged by both the first and second devices, and in a velocity control mode at other times. Additionally or alternatively, the third device can operate in a torque control mode, when a sheet is concurrently engaged by both the second and third devices, and in a velocity control mode at other times. Transition control modes can be implemented to generate smooth transitions between modes.
