The copier has two power save modes to reduce overall power consumption
thereby reduce the cost of operation. In addition, these modes conserve
natural resources and help reduce environmental pollution. The two power
save modes are preheat mode and auto power shut-off mode.

User programs
The preheat activation time and the auto power shut-off time have been
preset at the factory to 90 sec. for preheat mode and 30 min. for auto power
shut-off mode. These times can be changed using user programs. It is
suggested that you set appropriate times according to the actual usage of
the copier.

When the copier enters the preheat mode, the POWER SAVE indicator will
light up and other indicators will remain on or off as before. In this condition,
the fuser in the copier is maintained at a lower heat level, thereby saving
power. The preheat level is, however, high enough to allow the copier to
come to a ready condition or begin copying within 10 seconds after any key
input or copier operation such as paper tray operation is performed.

When the copier enters the auto power shut-off mode, the POWER SAVE
indicator will light up and all other indicators will go out. The auto power
shut-off mode saves more power but requires a longer time to warm up before
copying can begin.
