Waste Toner Recovery Unit
The waste toner recovery unit contains a bottle that collects waste toner
carried from the drum cleaner via screw conveyer belt. Attached to the right
and left sides of the bottle's neck are the light emitters and receptors of the
waste toner bottle full sensor (WTBF), which detects the full condition. To the
left lower side of the bottle, is the waste toner bottle set sensor (WTBS), which
detects if the bottle is missing or installed incorrectly (not properly seated).
