7.10.2 Detecting the State of the Waste Toner Bottle (full)

The machine checks the state of the waste toner bottle to see if it is full and thus to prevent overflowing of waste
toner. The waste toner bottle collects waste toner from 3 image formation units (drum cleaning unit, color toner
developing assembly, and ITB cleaning unit).
The amount of waste toner is checked with reference to the soft counter reading kept by the DC controller, and the
soft counter reading is based on computations of the following data:
1. paper size
2. color mode (full or mono)
3. image ratio
The DC controller monitors the soft counter at all times, and executes the following operation when the reading
exceeds the following:
Counter reading
210000 or higher
250000 or higher
*1: the message will read "Waste Toner Bottle Full" on the control panel.
*2: for details, see Memo.
