2.1.1 OVERVIEW
This copier provides the following forms of process control:
•
Potential control (done every process control self check)
•
Process control gamma calibration (done every process control self check,
after potential control)
•
Toner supply control (done every copy)
The components used for process control are:
•
Potential sensor (a new type of sensor is used, known as a ‘feedback
measurement potential sensor’). This sensor detects the surface potential of
the drum.
•
ID sensor (a new type of sensor is used, known as a ‘diffused reflection ID
sensor‘). The ID sensor detects the amount of toner on the drum.
