D046/D049 Fusing Units
Slide 215
The wattages of the lamps are different for each model also.
The connectors for the lamps are different, so it is not possible to install the
lamp for the wrong machine.
D049 hot roller
The roller contains three pipes with liquid in them. The liquid circulates
when the fusing lamps turn on. This makes sure that the temperature is
even all across the lamp (there are small differences in temperature in
different places across the lamp due to the coils in the elements – the fluid
in the pipes removes these differences).
Each machine has two fusing
lamps, a main lamp and a sub
lamp.
Both lamps are inside the hot
roller (no lamps in the pressure
roller).
Main lamp
D049/D155: The heating element
extends the entire length of the
lamp.
D046/D154: The heating element
covers only the center.
Sub lamp
D049/D155: The heating element
extends the entire length of the
lamp
D046/D154: There is a heating
element is at each end, and no
element in the center.
