    摘要： A bearing mount of a rotatable printer drum having a rotational axis includes a main drum bearing, rotationally supporting the drum and having an outer bearing race, and at least two secondary roller bearings, angularly spaced from each other. The secondary roller bearings are positioned to rollably support the outer bearing race and allow lateral translation of the main bearing.

    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.

    摘要翻译： 在喷墨打印设备中，喷墨打印头具有将墨水喷射到位于打印区域内的介质上的多个喷墨喷嘴。 驱动轴位于打印头的上游，并逐渐旋转以推动介质。 驱动轴具有纵向轴线，中心长度上的第一半径和小于第一凹部处的第一半径的第二半径和第二凹部，每个所述凹部围绕中心长度。 多个夹紧装置将介质稳定地抵靠驱动轴。 第一引导件与第一凹部对准，并且与驱动轴的轴线间隔开小于第一半径的第一距离。 第二引导件与第二凹部对准，并且与轴线间隔小于第一半径的第二距离。

    摘要： A print drum for carrying sheets of media during printing, including a rotatable carrier drum generally defining an outer cylindrical boundary about a drum axis, and at least one media control member extending laterally substantially parallel to the carrier drum axis. The media control member is controllably movable between (1) a first position extending beyond the carrier drum boundary to define a lateral alignment barrier for a leading edge of a media sheet when adding the media sheet to the carrier drum, (2) a second position beneath the outer cylindrical boundary when printing on the added media sheet, and (3) a third position projecting outwardly of the outer cylindrical boundary to push the leading edge of the added sheet of media away from the outer cylindrical boundary.
