ABSTRACT:
A cleaning head on a cassette of a drum cleaning apparatus is moved into contact with a drum to be cleaned. A cleaning sheet is moistened and passed between the drum and the cleaning head. The cleaning head is made of a resilient sponge-like material that evenly presses the cleaning sheet against the cylindrical drum during the cleaning operation. The cleaning sheet moves in a direction opposite to a rotation of the drum. The cassette body is removable from the frame to avoid interfering with printing.
