Principles of Operation
6. Fusing
The paper moves to the Fuser Assy where it passes between the Heat Roll and the Pressure Roll. The
Heat Roll melts the toner image and bonds it permanently to the paper. The paper then is transported
to the output tray.
7. Cleaning
The Cleaning Blade removes any toner that remains on the drum after the transfer process. Immedi-
ately after passing the Cleaning Blade, the drum passes under the BCR. The BCR applies an AC volt-
age to the surface of the drum to neutralize any electrical patterns remaining from the last print cycle.
The toner that the Cleaning Blade removes is collected inside the CRU. Toner that is reclaimed from
the drum is not reused by the CRU.
