6.4.6 DEVELOPMENT MECHANISM

This machine does not use developer, so a TD sensor is not necessary. In each AIO unit,
the toner supply roller [A] supplies toner to the development roller [B]. Electrostatic
attraction generated by the friction between the toner supply roller and development roller
moves toner to the surface of the development roller, and the development blade [C]
makes sure that the layer of toner on the development roller has an even thickness.
The discharge sheet [D] removes development roller bias.

6.4.7 TONER NEAR END AND END DETECTION

The machine uses the following to detect Toner Near End and Toner End:
Pixel count (memory chip on the AIO)
AIO rotation distance (memory chip on the AIO)
Once Toner Near End occurs, about 200 pages (A4, 5% coverage) can be printed until

toner end.
