Power supply Electrification roller unit OPC drum Exposure The LED head irradiates light on the surface of the OPC drum that is charged with a negative electrical load.
  • Page 30 Oki Data CONFIDENTIAL Development The negatively charged toner comes in contact with the OPC drum to fuse the electrostatic latent image by electrostatic force, to create a signiicant image on the surface of the OPC drum. The sponge roller precipitates toner on the development roller. The toner is then negatively electriied.
  • Page 31 Oki Data CONFIDENTIAL Fuser The toner image transferred on the paper is fused on the paper by heat and pressure when the paper passes through the heat roller and backup roller. The Telon coated heat roller is heated by a 800W or 350W internal halogen lamp, and backup roller is heated by a 50W internal halogen lamp.
