  • Page 22 2.4.2 Exposure Laser Photoco nductor drum In the exposure step, the laser printing head will emit a focused light beam to the surface of each photoconductor drum to write invisible images. The images formed for each color are called latent images or electrostatic images. The laser beam discharges only to the surface, causing the beam to hit the photoconductor drum.
  • Page 23 In case that the photoconductor drum is exposed for a long time, light or dark print quality problems may occur, and the print cartridge may need to be replaced. 2.4.3 Develop Toner adder Photoco roller nductor Develo drum Roller When the laser exposes the photoconductor drum, the HVPS will transfer the electric charge to the developer roller, which is evenly adhered with toner.
