ABSTRACT:
Paper chaff consisting of confetti, paper dust fibers or crimp lugs are scrubbed from continuous, edge-perforated computer paper between the paper supply and a printer by stationary brushes and are then captured in a collector chamber for subsequent removal. The collector chamber may be removed, emptied and reinstalled without severing the continuous paper web between the printer and the supply or retracting the paper from the printer. When in operative cleaning position, the chamber essentially confines the area where scrubbing takes place except for inlet and outlet slots through which the paper passes, in order to minimize dust particles from becoming airborne and migrating outside the confined area. In its preferred form, the collector chamber includes materials which electrostatically attract and collect such airborne particles. In one form of the invention wherein fan-folded paper is fed from a carton or box directly to a printer, the collector chamber may rest by gravity on or be fastened to the upper edges of the box.
