Abstract
Disclosed is an electrostatic printer having a rotatable drum with a photoreceptor belt mounted on the periphery. The photoreceptor belt is advanced past a cathode ray tube which forms an electrostatic image on its surface. A wiper brush is recessed within an opening extending transversely of the drum surface and is mounted for movement from the recessed position to a position in which it wipes the face of the cathode ray tube face as the drum is rotated. Also enclosed in conjunction with the wiper is a mechanism for periodically indexing the supply of photoreceptor web from a supply reel to a take-up reel both located interiorly of the drum. The photoreceptor is advanced by mechanism including planetary gearing.
