This seven step cycle is repeated for each sheet of paper that is sent through the printer. The seven steps in the print process are: Charge A bias charge roll places a uniform negative electric charge on the drum surface.
  • Page 265 The Magnetic Roll maintains an electrical potential relative to the charged surface of the drum. Negative charged areas of the drum have a lower electrical potential, or higher rel- ative negative value, than the Magnetic Roll. Discharged areas of the drum have a higher electrical potential, or lower relative negative value, than the Magnetic Roll.
