The total wattage of the fusing
lamp during copying is reduced
to 800 W, compared to the base
copier's 900 W. Because of this,
the ability to hold heat during
multi-copy runs will decrease,
and temperature will fall faster
from the target value, if the same
thin outer layer type hot roller is
used. To prevent this from
occurring, the A204/A206/A207
copiers hot roller has been
changed to a thicker metal
(Aluminum) core type so it can
hold heat during multi copy runs
without the temperature falling
too much. The secondary fusing
lamp is installed to achieve a
faster warm up time. Thickness
of hot roller: 7.0 mm.
This function can be performed
by pressing the DF key on the
operation panel.
This function has been newly
added. This function is suitable
for copying photographic
originals.
The customer can select
whether to have an image on the
OHP slip sheet or not.

Two fusing lamps are controlled
separately to keep the operating
temperature of the center and
edges of the hot roller at a
suitable value. This system
allows the temperature at the
center and at the edges to be
controlled more precisely.
Thickness of hot roller: 2.8 mm.
