Fuji Xerox Internal Use Only Disclosed to : FXPI Protected until : None Author : TSD & R.Buenaventura Prepared on : August 31, 2015 Objective: Each participant will understand what is xerography, how does it work and its processes. Each Participant will understand the difference between analog and digital process and its advantages. Each participant will be able to use the basic procedure in safely handling the machine. Each participant will be able to analyze the machine processes using the schematic diagram and fault isolation procedure. © 2014 Fuji Xerox Co., Ltd.

Its is the medium that recieves,processes, and transfer images using static electricity. Most small copiers, fax machines, and printers use drum type photoreceptors like the one shown below. Large equipment uses belt type photoreceptor. © 2014 Fuji Xerox Co., Ltd.

Let’s look at the photoreceptor as a flat object. There are four layer of photoreceptor: The substrate – connects the photoreceptor to the ground, completing an electrical circuit. The oxide layer – connects the photoconductive layer to the substrate. The photoconductive layer – is the layer that is affective by light. As long as this layer is in darkness, it acts as an insulator, kepping the charge on the trapping layer. The trapping layer – stores the static charge. © 2014 Fuji Xerox Co., Ltd.

This allows the charge on the trapping layer to pass through the oxide layer to the substrate. © 2014 Fuji Xerox Co., Ltd.

Prepared on : August 31, 2015 Therefore, ionized air is air with some of its electron removed. Since the electrons are negatively charged, the air in the area of the corotron becomes positively charged. Because this positively charge air is so closed to the photoreceptor, it steals electrons from the photoreceptor. This cause the photoreceptor to become positively charged. © 2014 Fuji Xerox Co., Ltd.

Therefore, the photoreceptor maintains this charge. © 2014 Fuji Xerox Co., Ltd.
