The cleaning system includes a cleaning device associated with each printing cylinder, which includes a rotatable brush roller that is selectively movable into and out of engagement with the respective printing cylinder. Each cleaning device further includes a cleaning fluid distribution tube for applying cleaning fluid to the brush roller to facilitate removal of foreign matter from the printing cylinder during a cleaning operation and a flicker bar that is selectively engageable with the brush roller to effect removal of foreign matter and used fluid carried thereby. Each printing unit includes an associated control module that is operable for connecting the cleaning devices of the associated printing unit with outside pneumatic, hydraulic, cleaning fluid, and electrical power sources and for controlling the operation of the cleaning devices of the associated printing unit.
