    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.

    摘要: Devices and methods provide route guidance by maintaining a plurality of user preferences, receiving a beginning location and an ending location of a trip, and receiving a trip purpose of the trip. Such devices and methods automatically generate multiple different routes between the beginning location and the ending location, automatically create a subset of less than all of the user preferences that match the trip purpose to produce purpose-specific preferences, and automatically rank the multiple different routes by ranking routes that match more of the purpose-specific preferences ahead of routes that match less of the purpose-specific preferences to produce a ranked order. Then, such devices and methods automatically output the multiple different routes in the ranked order.

    摘要: A method of operating a printer produces duplex images with improved throughput. The method monitors the position of an area of pressure roller that carries release agent and synchronizes a media transport to insert a media sheet into a nip formed with the pressure roller so the release agent on the pressure roller exits the nip as the leading edge of the media sheet enters the nip. The circumference of the pressure roller is an integral number times the length of the media sheet plus inter-document gap.

    摘要: An inkjet printhead is configured to reduce the likelihood of media coming into contact with a printhead face. The inkjet printhead includes a housing, an aperture plate having a plurality of apertures in an aperture area through which inkjet ejectors eject ink, and a pair of members aligned with a direction of media movement and extending along a length of the aperture area, the pair of members being configured to lift media away from the plurality of apertures in the aperture area.

    摘要: A closed loop feedback method that continuously adjusts the lateral and skew position of a sheet includes a first sensor that is used to measure lateral sheet edge position. A second sensor measures the lateral sheet edge position at a certain distance from the first sensor. Sheet skew values can thus be calculated. Lateral and skew controllers provide outputs to lateral and skew actuators, respectively, to adjust the sheet position. A different method of registering sheets laterally and in skew enables active sheet deskew without translating the sheet in the cross-process direction. A sensor carriage position is controlled to find the sheet edge after which deskew control can start. The average value of the carriage position can then be fed in a feedforward manner to move the image location to match the average paper position. This achieves good average lateral registration and active skew control at a reduced cost.

    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.
