Abstract
A process for controlling the amount of film buildup on a photoreceptor surface caused by certain print mode and/or material throughput conditions in a single pass highlight color printer which enables or promotes photoreceptor filming by the DAD toner additive (i.e. zinc stearate). Such filming results in the tri-level Image Push defect. This process utilizes toner coated cleaner brushes to control the film buildup thus preventing the defect. This process defines a functional equation that maintains a toner concentration at the cleaner brush fiber tips thereby controlling photoreceptor filming.
