[A]: Waste toner bottle
[B]: Bottle feeler
[C]: Bottle detection sensor
Waste toner bottle detection
When lifted (! Mechanism), the waste toner bottle [A] pushes against the bottle
feeler [B]. The feeler pushes the actuator of the bottle detection sensor [C].
Waste toner full sensor
The waste toner full sensor [D] emits light. The light goes through the bottle if the
waste toner level is low. When the waste toner level is high [E], the light path is
blocked, and "Waste Toner is Almost Full" is displayed. After this, when 4.58-billion
pixels have been printed, "Replace Waste Toner" is displayed. In this case, the
machine continues printing until the job ends (or the right cover is opened). When
the job ends, the machine does not process any more jobs until the waste toner
bottle is emptied.
NOTE: 4.58-billion pixels are equivalent to 2,721 sheets of LT/A4 paper (5%
coverage)
To keep the waste toner level, the waste toner bottle vibrates each time the
transfer belt drive unit turns 90 degrees. The interface roller on the belt tension unit
(! 6.3.6) creates this vibration when it turns.
