Theory of Operation
The data path of image data is shown in the following figure.
Process Control
For stable printing, the parameters related to forming both the electrostatic
and toner image are continuously monitored and adjusted by the printer.
Parameter correction and control over the entire printing process is called
“process control”. There are two main areas of control:
■
Bias Control
■
Toner Density Control
To supplement these two controls, the following are provided:
■ High-Area Coverage Mode Control
■ Admix Mode Control
■
Toner Density Control (CTD) Sensor (ADC - Automatic Density Control)
