2.2.10. Cleaning

[B]
The cleaning unit and the used toner tank are contained in the CTM.
The cleaning blade [A] removes any toner remaining on the drum after the im-
age is transferred to the paper. A magnetic roller [B] then brings the toner into
the used toner tank [D]. The mylar blade [C] scrapes the toner off the mag-
netic roller into the used toner tank [D].
When the CTM is removed from the machine, the cleaning roller cover [E] is
closed by a spring. This prevents removed toner from falling out of the unit.
There is no used toner overflow detection mechanism because the used
toner tank is large enough for the lifetime of the CTM.
