PHOTORECEPTOR PRECLEAN AIR SYSTEM (Cont'd)

such as blocking layers, charge generating layers and charge transport layers. Prior to coating, the metal cylinders are turned on a lathe and solvent cleaned. When, the turned cylinders are subjected to conditions where contaminants can accumulate on the surface prior to coating, such as during handling, packaging, shipping, transport or the like, the cylinders should be cleaned to prevent formation of defects in the subsequently applied coatings. The contaminants can comprise particulate such as dust, fibers and the like from the ambient atmosphere, packaging materials and the like.

To achieve clean turned cylinders prior to application of one or more coatings in a clean room 30 shown in the accompanying figure, a device is utilized in or adjacent to a wall 3 1 which separates a clean room from a non clean or less clean area. The function of the device is to remove loose particulate from cylindrical substrates 8 by removing any electrostatic charge on the cylindrical substrates 8 and then directing an gas stream 33 onto cylindrical substrates 8 to flush away the particles and trap them in a filter (not shown). The cylindrical substrates 8 to be cleaned may be conveyed by any suitable means, su...
