Abstract

The figure illustrates schematically in cross-section the general configuration of an automatic reproducing machine. A process unit or cartridge 10 is inserted into the main body of the machine 8 and is capable of being withdrawn therefrom when used and replaced with a new cartridge or replaced with a cartridge capable of performing an operation that the present cartridge is not capable of performing. When the processing cartridge is included within the machine, a photoreceptor belt is transported around the various processing stations from charging station 14, exposure station 16 wherein the belt is exposed to a light image transmitted from the imaging platen 15 by the optical system 17. The thus formed electrostatic latent image is developed at development station 18 transferred to a copy sheet from a copy sheet supply 20 at transfer station 19 and the toner image subsequently fused on the copy sheet at fusing station 22 after which it is transported to the collecting tray 23. A trap 24 is provided to collect any paper fibers that may remain on the photoreceptor belt and any other debris after the transfer zone and before reaching the blade cleaner 26. The debris would would otherwise impair the ability of the blade to remove toner which would then show up on subsequent copies in background areas and thereby reducing copy quality. The trap comprises a strip-shaped pad extending transversely to the direction of motion of the photoreceptor and is made of compliant material such as polyurethane which is preferably faced with velour and arranged to brush lightly against the photoreceptor.
