Slide 176
This slide shows how toner and developer are mixed in the development unit to
make the toner density equal in all parts of the development unit.
The quantity of developer moved right by the backspill plate is the same as the
quantity moved left by the mixing auger.
It is the same as cross-mixing mechanisms in other copiers.
The doctor blade position cannot be adjusted.
