Abstract: A compact electrostatographic reproduction machine, including a platen for positioning a document sheet having an original image to be reproduced; and a plurality of separately framed, mutually aligning machine modules variously containing electrostatographic process elements and subassemblies. The plurality of machine modules includes a copy sheet input module (CIM) for holding and supplying copy sheets to a toner image transfer point to receive a toner image thereon; an electronic control and power supply (ECS/PS) module for providing power and logic control to various modules of the reproduction machine; an imager module for creating a latent image of the original image of the document sheet positioned on the platen; a customer replaceable process cartridge (CRU) module containing subassemblies for forming a toner image on a photoreceptive member; and a fuser module for heating and fixing a toner image on a copy sheet onto such sheet.
