Developing Bias; Developing System - Konica Minolta magicolor 1600W Service Manual

11. Developing section

Developing bias

• The developing bias voltage (Vb) is applied to the developing roller so that an adequate
amount of toner is attracted onto the surface of the photo conductor.
• The developing bias voltage (Vb) is supplied by the High voltage unit (HV).
• The developing bias voltage is applied to the developing roller via the supply roller.
• The developing bias voltage is also applied to the doctor blade.
• The developing bias voltage is turned ON at the same time that the developing motor is
energized and turned OFF at the same time that the developing motor is deenergized.
11.3.5

Developing system

• The machine employs the single-component, non-contact developing system.
• In the non-contact, single-component developing system, the magnetic brush does not
rub the surface of the photo conductor (or the image). This prevents a foggy image from
occurring and the photo conductor from being worn.
