FUSING UNIT

The Fusing Unit fixes permanently the developed image to the paper by applying
heat to the toner and paper. A given pressure is also applied between the Upper
and Lower Fusing Rollers, thereby providing a certain width of area of contact
between the two rollers. This offers a longer fusing time and, at the same time,
helps toner to be fused into the paper easily.
The Lower Fusing Roller is also provided with a heater lamp which heats the roller
from the inside to ensure stabilized fusing performance. It also minimizes wrinkles
and skewed feed that would occur due to variations in the roller's surface tempera-
ture during the early period after the power has been turned ON.
