The machine remains ready to make prints even when a waste toner case full alert has been issued.
2. detection based on a video counter reading
The machine executes detection when the waste toner case is 95% full (after a case full alert); the result is sent to the DC controller, which in turn communicates
to the main controller if the result of detection indicates that the case is 100% full.
When the waste toner bottle is full, printing stops.
From the time the waste toner full warning is given till printing stops, this device can print out a maximum of 1,000 sheets of both colour and mono-colour (based
on A4 sheets with 5% image ratio). These values are estimates and the actual values will depend on the way in which the device has been used.
The waste toner counter clears automatically when the waste toner case is replaced.
MEMO:
In this machine, to prevent the collected waste toner from accumulating like a heap and from overflowing out of the waste toner case, the waste toner screw built
in the waste toner case is rotated and the toner is made even. The waste toner screw is rotated by the motor (M12).
MEMO:
This machine also has a waste toner case replacement detection function. After opening and closing the main body front cover at the status of alarm, abnormality
of the waste toner level, the case is judged as having been replaced when it was detected as toner absence by the optical sensor (UN8) mounted on the back side of
the waste toner case.
