FUSING UNIT
The Fusing Unit functions to fix 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 Upper Fusing Roller is provided with two heater lamps - Main Heater
Lamp H1 and Sub Heater Lamp H2. This enables a warming-up time of
less than 5 min (at an ambient temperature of 20°C and with rated power).
The Lower Fusing Roller is also provided with a heater lamp (H3) 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 rollers surface temperature during the early period after
the power has been turned ON.
A wear-resistant coating has been applied to the surface of the Upper
Fusing Roller that also neutralizes any charges.
