Abstract

A single pass highlight color electrophotographic printing machine requires cleaning of the photoreceptor without contaminating the separate liquid developer materials. This may be accomplished by using either a reusable web cleaning system or a disposable web cleaning system. The reusable web cleaning system is mounted between the transfer station and charging station of the printing machine. The cleaning system has a reusable, porous mesh web, made from Mylar, Spandex, polyvinyl alcohol fiber, Teflon, cotton, or Tedlar, amongst others, which is driven either with or a ainst the

As the web advances, it passes through a vacuum cleaner which removes particles and solvent adhering to the web. This renders the web reusable. Mechanical scourers, e. g. brushes or blades, may also be employed as part of the vacuum cleaner. The application of an electrostatic field on the web skive or mechanical members m...
