Abstract: The present invention is an automated arrangement for applying strip material to a web belt. One purpose of the present invention is to provide a solution to the known problem of securing material to an organic photoconductor (“OPC”) belt material in an automated manufacturing environment. Usually, material is applied to an OPC belt by hand. Hand application of strip material is time-consuming, costly, and prone to inaccurate placement on the OPC belt. The extra time taken to apply the strip material by hand increase the OPC belt's exposure to light, which can damage the OPC material. Furthermore, pulling the strip by hand can deform the strip because of excessive force used to pull the strip before application. Thus using an automated, controlled process to apply material minimizes damage to the belt and strip, resulting in higher yield of belts and strips per spool.

Abstract: The present invention is directed to a shutter system for electrophotographic machines that effectively reduces the impact of ambient light-on the photoreceptor, or image-bearing member. The shutter system of the present invention utilizes a shutter member that substantially covers the cartridge chamber when in a closed position. Preferably, the shutter member is disposed at the opening of the cartridge chamber. The shutter member is held in place by one or more support brackets.

Abstract: A jump monocomponent development arrangement includes a dielectric photoreceptor belt having an image-bearing surface for receiving an electrostatic charge image and a development station having a supply of toner particles with a mean diameter in a range from 8 microns to 14 microns and including large and small additive particles having mean diameters in size ranges of 6 to 12 nm and 20 to 50 nm, respectively, and in amounts sufficient to provide surface coverage of the toner particles in ranges from about 5 percent to about 50 percent and about 50 percent to about 150 percent, respectively.

Abstract: A spacing device for image processing systems to maintain a development gap between an image-receiving member and a developer roller thereby facilitating efficient development and consistently maintaining high image quality and methods for manufacturing and using the same. The spacing device comprises one or more spacing members that have preselected lengths and that are configured to be coupled with, and extend from, an imaging-receiving module and/or a developer cartridge of an image processing system. When the image processing system is properly assembled, a predetermined development gap is formed between an image-receiving member of the imaging-receiving module and a developer roller of the developer cartridge, and the spacing members are disposed substantially between, and in contact with, the imaging-receiving module and the developer cartridge. The spacing members, being formed from a substantially rigid material, are configured to maintain the predetermined development gap.

Abstract: The present invention is directed to a method and system for tracking a photoconductor belt loop in an image forming apparatus that effectively monitors and compensates for changes in the OPC belt's speed and position as well as for possible contamination of the code strip and damage to the photo sensors. There is provided a method and system for sensing a code strip on the photoconductor belt loop with a first sensor, producing a first signal, sensing a code strip on the photoconductor belt loop with a second sensor, producing a second signal, computing a phase shift error between the first and second signals; and synchronizing first and second signals.
