SYMPTOM
The following sometimes occur:
1. Misdetection of the waste toner bottle full condition
2. Toner bottle cannot be pulled out from the toner bank unit
CAUSE
1. Misdetection of the waste toner bottle full condition
Toner may scatter to the outer portion of the toner bank unit when the toner bottle chuck
opens the bottle. The split toner covers the detection area of the toner overflow sensor,
causing it to mis-detect the waste toner bottle full condition.
2. Toner bottle cannot be pulled out from the toner bank unit
When toner is supplied to the toner bank unit, it may leak out from the bottle and gradually
accumulate in the chuck area, eventually preventing the bottle-holding mechanism on the
chuck from releasing the bottle.
