Abstract: An apparatus for rotating a sensing device about a pan axis and a tilt axis may include an enclosure, first and second rotatable dials configured to allow a user to adjust an angular pan orientation and an angular tilt orientation, respectively, of the sensing device. The apparatus may include outer and inner concentric shafts attached to the first dial and the second dial, respectively. The apparatus may also include a frame assembly attached to the outer shaft such that the frame assembly rotates about the pan axis as the first dial is rotated. The frame assembly may include a base configured to rotate about the tilt axis and that supports the sensing device. The frame assembly may also include a pin and gear assembly operatively coupling the base to the inner shaft such that rotation of the second dial rotates the base about the tilt axis.

Abstract: A backup roller is formed by a member having a rotational axis and a circumferential region around which a plurality of teeth are arranged. Each tooth of the plurality of teeth has a tip end extending in a direction away from the rotational axis. When the backup roller is rotated the tip end of each of the plurality of teeth sequentially extends toward the rotational axis of a drive roller at an angle non-orthogonal to the rotational axis of the drive roller.

Abstract: A print media feed system for advancing a sheet of print media having a leading edge and a trailing edge in a sheet feed direction through a print zone in an imaging apparatus includes a rotating support positioned downstream of an exit roller in relation to a sheet feed direction. The rotating support provides a rotating support surface that engages a non-printed side of the sheet of print media downstream of the exit roller while the trailing edge of the sheet of print media is advanced through the print zone by the exit roller, the rotating support not contributing to advance the trailing edge of the sheet of print media through the print zone, but contributing to advance the sheet of print media after the sheet of print media is released by the exit roller.

Abstract: Methods and apparatus for increasing the bias force between a developer half and a cleaner half of a process cartridge are disclosed. One or more springs are interposed between the cleaner half and the developer half of the process cartridge. These springs are of sufficient strength to maintain a constant separation between the developer and the photosensitive member of the process cartridge. Sources of force other than springs, such as weights or elastic members may also be employed to provide and increase the bias force urging the developer and photosensitive member together.
