Toner Level Detection - Canon imageRUNNER ADVANCE 8105 Series Service Manual

MEMO
The Toner Excess Supply Sensor (TS2) detects amount of toner around the Buffer
Inlet. If toner is supplied excessively from the Sub Hopper to the Buffer Unit (if
there are toner clusters), toner in the Buffer may overflow.
If TS2 detects presence of toner, regardless of presence/absence detection of
toner by TS3, the Toner Supply Motor (M10) is stopped so that toner supply to the
Buffer is stopped to prevent toner leak

Operation
When TS3 detects absence of toner, the
Toner Supply Motor (M10) is driven.
Once TS3 detects presence of toner, M10
is stopped (to prevent toner leak).
When TS3 detects absence of toner, the
Toner Supply Motor (M10) is driven.
Once TS3 detects presence of toner, M10
is stopped (to prevent toner leak).
In the case that toner presence failed to
be detected 90 sec after the drive of M10
has been started, a message is displayed
in the bottom of Control Panel because
the system determines that there is
no toner in the Toner Container. This
state continues during printing and the
Toner Container can be replaced during
printing.
After the Toner Container is replaced, the
toner level returns to 100%.
