6.15.7 CLEANING MECHANISM
The cleaning roller [A], in constant contact with the pressure roller [B], collects
toner and paper dust from the surface of the pressure roller.
Because the cleaning roller is metal, it can collect adhering matter better than the
pressure roller, which is coated with Teflon.
Some new design features have been implemented in order to cope with the lower
temperatures required for new toner which has a melting temperature much lower
than the previous toner. The cleaning roller [A] is composed of an aluminum shell
with an internal “heat pipe” suspended in the middle of the roller to dissipate heat
more rapidly.
