Toner Bottle ID Chip
A contact type ID chip is provided in each toner bottle which stores residual toner and various toner counters, toner end history, and model serial number.
Data read and write to the ID chip contact board is performed by contact with the ID chip contact board installed in the machine.
Toner Supply (Sub-hopper - Development Unit)
The sub-hopper can hold Bk: 24.7 cc (equivalent to 230 sheets of 5% chart), or Color: 19.3 cc (equivalent to 150 sheets of 5% chart) of toner.
Toner which has fallen into the sub-hopper is homogenized by an agitator (Mylar sheet: 2 for BK, 1 for each color).
After being horizontally transported by the coil, toner in the sub-hopper falls directly into the development unit.
