toner up to the waste toner container [E].
The collected waste toner is moved to the left side of the AIO by the waste toner collection coil [D].
A flexible sheet [F] separates the unused toner area from the waste toner area. The waste toner area
becomes larger when toner is consumed.
Toner Mixing and Transport
The toner moves as shown in the above drawing. The toner agitator [A] mixes the toner so that it is
transported evenly to the mixing rollers. The upper mixing roller [B] moves toner to the center, then the
lower mixing roller [C] moves toner to the right and left sides. Finally, the toner supply roller [D] supplies
toner to the development roller. This mixing mechanism prevents toner hardening and uneven image
density in the outputs.
Toner Near End/ End Detection
To detect the toner near-end and the toner end, the machine uses:
•
Pixel count (memory chip on the AIO)
•
AIO rotation distance (memory chip on the AIO)
After near-end, it is estimated that 200 pages (A4, 5% coverage) can be printed until toner end occurs.
When toner end detects, the machine halts.
