    • A document printer/copier comprises a pair of drum-support members for rotatably supporting an image-recording drum and, optionally, an intermediate image-transfer drum. At least one of such drum-support members is adapted to be decoupled from the drum(s) it supports and be moved to a position within the machine frame in which it does interfere with the replacement of the drum(s)'s outer layer. Preferably, such member comprises a selectively energizeable clamp which, when energized, clamps onto an axle bearing of a drum and thereby supports the drum for rotation. When de-energized, the clamp releases the drum bearing, enabling the drum-support member to be slid axially along the drum axis to a position spaced from the drum axle, and thereafter pivoted to a position spaced from the drum axis where it does not interfere with drum servicing and/or replacement.
    • 文件打印机/复印机包括一对鼓支撑构件,用于可旋转地支撑图像记录鼓和可选地中间图像转印鼓。 这样的鼓支撑构件中的至少一个适于与其支撑的滚筒分离,并移动到机架内的位置,在该位置中干扰鼓的外层 。 优选地,这种构件包括可选择性地通电的夹具,其在通电时夹紧在滚筒的轴承上,从而支撑滚筒以进行旋转。 当断电时,夹具释放滚筒轴承,使得滚筒支撑构件能够沿着滚筒轴线轴向滑动到与鼓轴间隔开的位置,然后枢转到与滚筒轴线间隔开的位置 干扰鼓服务和/或更换。
