Energy Saving Control Function
The device comes equipped with a Low Power Mode where energy consumption is reduced after a certain amount of time
elapses since the device was last used, as well as a Sleep where printer and fax functions remain in a waiting state but
power consumption is still reduced to a minimum when there is no activity with the device within a set amount of time.
Sleep
The device automatically enters Sleep when 60 minutes have passed since the device was last used. The amount of time
of no activity that must pass before Sleep is activated may be lengthened. For more information refer to Sleep section.
Low Power Mode
The device automatically enters Low Power Mode when 3 minutes (for P-C4580DN) or 5 minutes (for P-C5580DN) have
passed since the device was last used. The amount of time of no activity that must pass before Low Power Mode is
activated may be lengthened. For more information refer to Low Power Mode section.
Automatic 2-Sided Print Function
This device includes 2-sided copying as a standard function. For example, by copying two 1-sided originals onto a single
sheet of paper as a 2-sided copy, it is possible to lower the amount of paper used. For more information refer to
Duplex
(Setting the duplex printing) on page 6-30.
Printing in duplex mode reduces paper consumption and contributes to the conservation of forest resources. Duplex mode
also reduces the amount of paper that must be purchased, and thereby reduces cost. It is recommended that machines
capable of duplex printing be set to use duplex mode by default.
Resource Saving - Paper
For the preservation and sustainable use of forest resources, it is recommended that recycled as well as virgin paper
certified under environmental stewardship initiatives or carrying recognised ecolabels, which meet EN 12281:2002*
1
or an
equivalent quality standard, be used.
This machine also supports printing on 64 g/m
2
paper. Using such paper containing less raw materials can lead to further
saving of forest resources.

Your sales or service representative can provide information about recommended paper types.
Environmental benefits of "Power Management"
To reduce power consumption when idle, this machine is equipped with a power management function that automatically
activates energy-saving mode when the machine is idle for a certain period of time.
Although it takes the machine a slight amount of time to return to READY mode when in energy-saving mode, a significant
reduction in energy consumption is possible. It is recommended that the machine be used with the activation time for
energy-saving mode set to the default setting.
