Operation cycle B. Outline of print process The printer section of this machine employs the laser print system where print images are formed by the laser beams on the OPC drum. A high voltage (corona) is applied from the main charger to the OPC drum to charge the OPC drum. Laser beams are radiated to the charged OPC drum to form electrical images o[...]

(2) Exposure A Laser beam is generated from the semiconductor laser and control- led by the print pattern signal. The laser writes onto the OPC drum surface through the polygon mirrors and lens. The resistance of the OPC layer decreases for an area exposed by the laser beam (cor- responding to the print pattern signal). The beam neutralizes the neg[...]

(7) Optical discharge (Semiconductor laser) Before the drum rotation is stopped, the semiconductor laser is radiated onto the drum to reduce the electrical resistance in the OPC layer and eliminate residual charge, providing a uniform state to the drum surface for the next page to be printed. When the electrical resistance is reduced, positive char[...]
