Photocopiers 

• The charge: Every laser printer and copier has a photoreceptor, which is a light-sensitive layer. It is a flexible belt or drum that has a tiny layer of photoconductive material added to it. Once confronted with light, the photoreceptor changes from being insulation to conducting. By providing a high DC voltage to nearby wires, which creates a strong electric field close to the wires and ionises the air molecules, it is charged in the dark. An electric field is produced across the surface of the photoreceptor by the deposition of ions with the same polarity as the voltage on the wires.
  
  
• Disclose: With a light-emitting-diode image bar or scanning modulated laser, the image is exposed to the photoreceptor in a xerox machine. A lighted image's reflected light is thrown onto the photoreceptor in earlier analogue copiers. The portions that are darker keep their charge.
  
  
• Increase: Toner is the name for the pigmented powder used to produce the image. Between five and ten micrometres in diameter, toner particles composed of colourant and plastic resin have finely regulated electrostatic characteristics. Magnetized carrier beads are used to convey them to the development zone, where they are combined with and charged. The charged toner clings to the picture due to an electrostatic force generated by the electric field connected to the charge pattern of the image on the photoreceptor. A printer with four distinct xerographic components that produce and develop distinct cyan, magenta, yellow, and black pictures can produce a colour document. The superposition of these particle images yields full-colour papers.
  
  
• Transferring: By putting the paper into touch with the toner and then providing a charge with polarity opposite to that of the toner, the powder image is transferred from the photoreceptor onto the paper. The charge must be sufficiently powerful to dislodge the powder's grip on the photoreceptor. The paper, which is now holding the picture, is released from the photoreceptor by a second carefully controlled charge.
  
  
• Fuse: The toner that makes up the image is melted and fused to the paper during the fusing process. The paper is run through two rollers to accomplish this. The toner is melted by a heated roll, which is then compressed by the second roll to fuse the toner to the paper.
  
  
• Clean: It is necessary to clean the photoreceptor before the subsequent print cycle since toner transmission from the photoreceptor to the paper is not always perfect. A revolving brush cleaner is used to accomplish this in the majority of medium- and high-speed copiers and printers.
