Abstract: A printer or copier has a photoconductive drum which is to be cleaned of residual toner after printing by a brush as a principal cleaner and by a stripper element of an abrasive-resistant film as an auxiliary cleaner. The stripper element of plastic film presses against the photoconductive drum at an angle to remove substances adhering to the drum. A pivot mounting may be provided for the stripper and a transverse moving device for moving the stripper may also be provided.

Abstract: A device for transporting printing media (12) in printers or copiers has transporting elements (36), arranged rotatably in a printing medium transport channel at a distance from the printing medium (12), as a feeding aid for an automatic paper feeding device. Located on the circumferential region of the transporting elements (36) are friction elements (40) which are bound, so as to be deflectable in the manner of impact elements, to the axis of rotation (38) of the transporting elements (36) and have friction surfaces (41) which, due to centrifugal force during rotation of the transporting elements (36), move the friction elements (40) out of a rest position, counter to a restoring force, via their friction surface (41) into frictional contact with the printing medium (12) and transport the latter. The friction elements (40) release the printing medium (12) when the transporting element (36) is stationary.
