Abstract: A cleaner band stretchably disposed, across the imaging surface width, between two rotating cleaner brushes. The cleaner band is slightly off center and down process from the brush backup roll. The cleaner band acts as a disturber for dislodging large agglomerate residual particles from the imaging surface.

Abstract: Disclosed is a developer composition which consists essentially of a toner consisting essentially of a resin, a colorant, and colloidal silica external additive particles and a carrier consisting essentially of a core, an optional coating on the core, and an external additive selected from the group consisting of metal salts of fatty acids, linear polymeric alcohols comprising a fully saturated hydrocarbon backbone with at least about 80 percent of the polymeric chains terminated at one chain end with a hydroxyl group, polyethylene waxes with a molecular weight of from about 300 to about 2,000 polypropylene waxes with a molecular weight of from about 300 to about 3,000, and mixtures thereof. Also disclosed are processes for using the aforementioned developer in a tri-level development process.

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.
