Power Saver This product is designed with an energy-saving mode called Power Saver. 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. The factory default Power Saver Timeout for this product is 20 minutes. By using the printer configuration menus, the Power Saver Timeout can be modified between 10 minutes and 30 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. 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. 53

Power Saver
This product is designed with an energy-saving mode called Power Saver. 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. The factory default Power
Saver Timeout for this product is 20 minutes.
By using the printer configuration menus, the Power Saver Timeout can be modified
between 10 minutes and 30 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.
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.
