Values are subject to change. See www.lexmark.com for current values.
Power Saver
This product is designed with an energy-saving mode called Power Saver. The Power Saver Mode is equivalent to
the EPA Sleep Mode. The Power Saver Mode saves energy by lowering power consumption during extended periods
of inactivity. The Power Saver Mode is automatically engaged after this product is not used for a specified period of
time, called the Power Saver Timeout.
Factory default Power Saver Timeout for this product (in minutes): 110V = 45 minutes, 220V = 60 minutes
By using the configuration menus, the Power Saver Timeout can be modified between 1 minute and 240 minutes.
Setting the Power Saver Timeout to a low value reduces energy consumption, but may increase the response time
of the product. Setting the Power Saver Timeout to a high value maintains a fast response, but uses more energy.
Off mode
If this product has an off mode which still consumes a small amount of power, then to completely stop product power
consumption, disconnect the power supply cord from the wall outlet.
Total energy usage
It is sometimes helpful to calculate the total product energy usage. Since power consumption claims are provided
in power units of Watts, the power consumption should be multiplied by the time the product spends in each mode
in order to calculate energy usage. The total product energy usage is the sum of each mode's energy usage.
