ABSTRACT:
An electrophotographic apparatus having an endless electrophotosensitive belt transportable past a plurality of work stations and including paper supply and transport means and a unitary control circuit which actuates work stations and other apparatus elements in a required succession and at frequencies which vary in accordance with copy magnification required. The control circuit itself is actuated in response to signals supplied by one of several rotatory switching means which are rotated synchronously with the electrophotosensitive belt, thereby ensuring matching of belt and apparatus element action.
The apparatus may further comprise detection switches which are disposed at various points along the path of travel of copy paper through the apparatus, and are actuable by passage of a sheet of copy paper, and the successive actuation of which is a necessary condition for continued actuation of the control circuit and sequential operation of work stations. Upon the occurrence of a paper jam and consequent failure of a sheet of copy paper to reach and actuate a detection switch, apparatus operation is stopped and a lamp or similar warning means indicative of the location of the paper jam is activated.
