ABSTRACT:
A contaminant removal head is disposed on a holder which is movable along a printing cylinder. The contaminant removal head includes a timing belt having a plurality of contaminant removal blades disposed at a predetermined pitch along the timing belt. The timing belt is rotatably disposed on a pair of spaced-apart timing pulleys driven by a motor that intermittently rotates the timing belt. A control unit controls the motor to position one of the contaminant removal blades adjacent the printing cylinder to remove contaminants therefrom. After contaminants have been removed from the printing cylinder, the motor rotates the timing belt to position a portion of the timing belt between adjacent contaminant removal blades adjacent the printing cylinder.
