Abstract
A rotating brush cleaning system is provided for removing debris, lint and ink from components of printing devices. Operation is effected by an air cylinder which periodically urges a rotating spiral brush cleaner against the component of the printing device and retracts the cleaner from the component of the printing device. The action of the cleaner in combination with rotation of the component of the printing device is such as to loosen dust and lint from the component, which dust and lint is then drawn into a vacuum system that surrounds the cleaner.
