    摘要： An image forming apparatus comprising an accumulator drum for receiving toner images from a plurality of imaging units and transferring the toner images to a receiving media. The basic components of the image forming apparatus comprise an accumulator drum having a plurality of imaging units with photoconductive drums positioned about the accumulator drum, and a laser assembly. In one embodiment, a laser emits light beams for forming a latent image on each of the photoconductive drums with each light beam having a different external optical path length. In one embodiment, a drive mechanism operatively connected to the imaging units drives the accumulator drum. In one embodiment, the imaging units are positioned about the accumulator drum is a specific angular placement. In one embodiment, the imaging units are at least partially positioned within the interior of the accumulator drum.

    摘要： A thermal printer (10) has a thermal transfer medium (28) fed past a thermal printhead (21) at a substantially constant velocity by a feed roll (82) engaging the thermal transfer medium just prior to the printhead to maintain a portion of the thermal transfer medium between the printhead and the feed roll relatively stiff. The feed roll is mounted on a cartridge (30) having the thermal transfer medium supplied therefrom. A drag brake (70) is disposed in the feed path of the thermal transfer medium prior to the feed roll to cause a substantially constant premetering tension to be applied to the thermal transfer medium irrespective of the coefficient of friction between the drag brake and the thermal transfer medium. A carrier (14), which supports the printhead and a feed roll driver (90), is driven separately from the feed roll driver so that various ratios between the velocities of the thermal transfer medium and the carrier are obtained to produce various print qualities. One print quality occurs in a draft mode, which is a relatively high speed, in which there is substantial conservation of the thermal transfer medium. The peel angle of the thermal transfer medium from a recording medium (12) on which printing occurs is maintained at a relatively low angle to increase the contact time between the thermal transfer medium and the recording medium.
