AIO (All In One) Cartridge

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

Toner Near End

To detect the toner near-end, the machine uses:
Pixel count (memory chip on the AIO)
AIO rotation distance (memory chip on the AIO)

Toner End

To detect toner end the machine uses:
Output from the TM sensor (center)
After near-end, it is estimated that 200 pages (A4, 5% coverage) can be printed until toner
end occurs.
