The OPC drum (diameter 100 mm) is charged by the charge corona unit, a standard Scorotron grid wire
charging and cleaning system.
The drum motor drives the drum and the drum cleaning unit. A counter blade system, with both cleaning
blade and brush, clean the drum.
Two sensors mounted near the drum, an ID sensor and potential sensor, are used for process control.
Toner is collected at the cleaning area and transported back to the development unit via the toner collection
coil and toner recycling pipe.
