Some modes may not apply to your product.
Mode
Description
Power consumption (Watts)
Printing
The product is generating hard-copy output from
electronic inputs.
Lexmark 3500 Series: 15; Lexmark 4500 Series: 18

The product is scanning hard-copy documents.
Lexmark 3500 Series: 10; Lexmark 4500 Series: 13
Ready
The product is waiting for a print job.
Lexmark 3500 Series: 8; Lexmark 4500 Series: 11
Power Saver
The product is in energy-saving mode.
Lexmark 3500 Series: 5.0; Lexmark 4500 Series: 7.7
High Off
The product is plugged into a wall outlet, but the power
switch is turned off.
not applicable
Low Off (<1 W Off)

is turned off, and the product is in the lowest possible
power consumption mode.

0.3
The power consumption levels listed in the previous table represent time-averaged measurements. Instantaneous power draws may be
substantially higher than the average.
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):
60
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.
