FUSER ROLL CLEANING METHOD AND APPARATUS FOR PERFORMING IT

摘要

The backup roll of a roll fuser for fixing xerographic images is periodically cleaned by passing plain paper through the fuser roll couple at a slow rate while the backup roll is heated above a toner melt temperature. Roll cleaning is accomplished automatically by providing a xerographic document copier with a special slow rate operating cycle wherein image production is inhibited so that plain paper is fed through the roll couple in accordance with the cleaning method.
