Specifies the amount of
time after a print job
before the MFP goes
into Power Saver mode.
Print the menu settings
page to determine the
current Power Saver
setting. When the MFP
is in Power Saver mode,
it is still ready to receive
print jobs.
Select 15 to put the MFP
in Power Saver mode 15
minutes after it finishes a
print job. This uses much
less energy, but requires
more warm-up time for
the MFP. Select 15 if
your MFP shares an
electrical circuit with
room lighting and you
notice lights flickering.
Select a high value if
your MFP is in constant
use. Under most
circumstances, this
keeps the MFP ready to
print with minimum
warm-up time. Select a
value between 15 and
240 minutes if you want
a balance between
energy consumption and
a shorter warm-up
period.
