  • Patent number: 7753595
    Abstract: 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.

  • Publication number: 20090035046
    Abstract: 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.

  • Patent number: 6808259
    Abstract: 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.

  • Patent number: 6682190
    Abstract: In an inkjet printing apparatus an inkjet printhead ejects ink into a print-zone. A drive shaft, located upstream of the printhead, 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 recess is peripheral to the central length. A plurality of pinch devices stabilize the media against the drive shaft. A first guide and a second guide, spaced from the longitudinal axis, are aligned with and extend into the first recess and second recess.
