CONTROL CIRCUIT IN AN ELECTROPHOTOGRAPHIC COPYING MACHINE Abstract of the Disclosure In a copying machine comprising a photoconductive belt (5) that is moved past a number of processing stations in order to make copies, the belt (5) is divided relative to a reference point into a plurality of imaging sections each of which is capable of copy formation. Each imaging section is subject to deterioration as a function of the number of times a copy has been made with the use of that imaging section. A control circuit (100, 110) is provided comprising a counter memory (102) that for each imaging sec- tion stores the number of copies made with the use of that imaging section. The control circuit (100, 110) further com- prises means (103, 105, 106, 107) which, as a function of the count in the memory (102) for a particular imaging section, adjust one or more of the processing stations when a process- ing station is acting on that imaging section. The control circuit (110) further comprises means (116, 120, 121, 122, 123) to prevent copy formation on a particular imaging sec- tion when that imaging section is no longer suitable for copy formation either because haying been used a maximum number of times in copy formation or because of having been damaged.
