Electrophotographic recording apparatus

摘要

An electrophotographic recording apparatus incorporating an electrostatic recording head disposed in closely spaced gap-defining proximity to the surface of a rotatable charge carrying drum additionally includes a light source for illuminating the gap when a housing door of the copier is open. The illuminated gap is thereby readily visible to facilitate verification of proper spacing between the drum surface and the recording head. A manually operable switch disposed within the housing permits normally-disabled rotation of the drum when the housing door is open so that the presence and width of the gap may be verified along the entire circumference of the rotatable drum.
