Abstract
Feeder systems are mechanical systems that feed individual sheets of paper to other mechanical devices. Feeder systems need to be able to handle a variety of types of paper with different weights and finishes. Glossy paper has proven difficult to feed because of anti-offset agents used in the printing process. The agents contaminate the rollers in the feeder system causing misfeeds and jams. The present invention is a cleaning apparatus that can be used in conjunction with the feeder system to keep the feeder system free from malfunctions during the processing of glossy paper. The cleaning apparatus includes a cleaning head mounted on a supporting arm. Various types of abrasive cleaning heads can be employed in the cleaning apparatus such as metal blades, meshes and brushes. The cleaning heads keep the rollers operational while minimizing deterioration of the roller.
