This product has the following two power reducing modes that conform to the
Energy Star guidelines to help conserve natural resources and reduce
environmental pollution.

Preheat mode
The preheat mode is the first level of power reduction. The power is reduced
to the fuser unit a preset time after the machine has completed a job and no
further machine operations have been performed. The machine can recover
to the ready condition within a short period of time. The preset time to enter
the mode can be set by a administrator settings.

Auto power shut-off mode
The auto power shut-off mode is the second level of power reduction. In this mode power is shut off to the
fusing unit and the touch panel. In this state more energy is saved than in the preheat mode but the time to
recover to the ready condition will be longer. The preset time to enter this mode can be set by a administrator
settings.

When this product is used as a printer, and either of the above modes is active, the mode will be deactivated
automatically by an incoming job and the machine will automatically warm up and start to print when it has
reached the ready temperature.
When this product is configured for multi-function operation, and either of the above modes is active, the mode
will be deactivated as above by an incoming print job. Either mode will also be deactivated by operation of
DOCUMENT FILING, IMAGE SEND or COPY mode key.
