Uses these components:
TD sensor: Detects how much toner there is in
the developer
ID sensor: Measures the density of standard
sensor patterns during process control.
Pixel counter: Counts pixels to determine how
much toner for each color is used on the page
The result of toner supply control determines
how long the toner supply motor turns on for.
This determines the amount of toner supplied.
This is done before every development for each
