left to reach the full level of and the total counter value
waste toner) exceeds 50,000 sheets.
Full level of waste toner fter approx. 2000 sheets have
(0% left to reach ful been printed by starting the
Developing Assembly
When replacing a Waste Toner Box and the Waste Toner Full Sensor detects absence of
waste toner after the Waste Toner Full Sensor detected presence of a Waste Toner Box, the
counter of the Waste Toner Box is cleared. When replacing a Waste Toner Box before the
alert, be sure to clear the following in service mode: COUNTER > DRBL-1 > WST-TNR
Special full level detection
When attaching a Waste Toner Container that has been used by the other machine, or the
counter information is lost for some reason, it is necessary to notify full level before an alert
is given. (The counter shows less than 50,000 although the sensor detects full level of waste
toner) In such a case, it is determined as full level without an alert and the machine cannot
continue printing.
Explain the user that there will be no alert when any of the above is executed.
