If the Power Saver Mode is affecting the effective use of this printer,
this mode can be disabled from the Setup Menu (see page 88).
Total energy usage
It is sometimes helpful to calculate the total printer energy usage.
Since power consumption claims are provided in power units of
Watts, the power consumption should be multiplied by the time the
printer spends in each mode in order to calculate energy usage.
The total printer energy usage is the sum of each mode's energy
usage.
