[A]: Fusing belt lubrication roller
[B]: Fusing belt
[C]: Hot roller
[D]: Cleaning roller – fusing belt lubrication roller
[E]: Cleaning felt roller
[F]: Pressure roller
The fusing unit uses two lubrication rollers saturated with silicone oil to prevent
toner and paper dust from clinging to the fusing belt.
The fusing belt lubrication roller [A], contacts the fusing belt [B] above the hot roller
[C]. This lubrication roller applies a very thin coat of silicone oil to the fusing belt
where the belt contacts the roller.
A cleaning roller [D] cleans the surface of the fusing belt lubrication roller.
The cleaning felt roller [E] cleans the surface of the pressure roller [F].
