6.2 COLLECTION OF USED TONER
The toner collection coil moves used toner from the cleaning unit through the
used toner pipe [A] to the used toner tank [B]. The used toner tank can hold
about 800 grams of toner. On average, about 10,000 A2 sized copies can be
made before the used toner tank needs to be emptied. (This assumes 7%
originals and 80% transfer efficiency.) The toner overflow sensor [C] detects
when the used toner tank is full.
The toner collection bottle is vibrated to prevent used toner from building up in
one place and activating the toner overflow sensor too early. The shaft of the
first set of transport rollers has a cam [D] on the end. This cam is in contact
with a projection [E] of the used toner bottle. It turns when the main motor is
on and moves the used toner tank up and down as shown above right.
