    2MH/2MJ/2MK/2ML 2-1-2 Drum section (1) Drum section The durable layer of organic photoconductor (OPC) is coated over the aluminum cylinder base. The OPC tend to reduce its own electrical conductance when exposed to light. After a cyclic process of charging, exposure, and development, the electrostatic image is constituted over the OPC layer.

  • Page 204: Main Charger Unit

    2MH/2MJ/2MK/2ML (2) Main charger unit As the drum rotates in a “clean (neutral)” state, its photoconductive layer is given a uniform, positive (+) corona charge dispersed by the main charger wire. Due to high-voltage scorotron charging, the charging wire can get contaminated by oxidization after a long run. Therefore, the charger wire must be cleaned at a specific interval.

Toner attracts to the magnet sleeve since it is powdery ink made of black resin bound to iron particles. Developing blade, magne- tized by magnet, is positioned approximately 0.3 mm above the magnet sleeve to constitute a smooth layer of toner in accordance with the magnet sleeve revolution.
