Abstract
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.
