Abstract

In an electrophotographic apparatus, electrostatic latent images are formed on an endless photoreceptor belt for subsequent development by toner particles and transfer of the toner image to output sheets. The belt has at least two sections around its length on which images are formed. If a defect occurs in one of the belt sections, the defective belt section may be disabled, so that the formation of images on that section is prevented, while images may be formed on at least one remaining belt section. Processes for disabling at least one section of an endless photoreceptor belt are disclosed in, for example, U.S. Patent 5,173,733.

In an electrophotographic apparatus, electrostatic latent images are formed on an endless photoreceptor belt for subsequent development by toner particles and transfer of the toner image to output sheets. The belt has at least two sections around its length on which images are formed. If a defect occurs in one of the belt sections, the defective belt section may be disabled, so that the formation of images on that section is prevented, while images may be formed on at least one remaining belt section. Processes for disabling at least one section of an endless photoreceptor belt are disclosed in, for example, U.S.
Patent 5,173,733.

In many instances, the defective section of the photoreceptor belt is determined by the user, by, for example, manual inspection of a number of copies equal to the number of sections of the belt. Determination of which section of the photoreceptor contains the defect can be facilitated by printing a different number on each section of the photoreceptor belt during a diagnostic print run. The user can then determine easily which numbered section is defective by visual inspection of the documents generated during the diagnostic print run. The number ca...
