Lenovo M720 energy consumption
The following table documents the energy consumption characteristics of the Lenovo M720.
Mode
Printing
Copying
Scanning
Ready
High Off
The power consumption levels listed in the previous table represent time-averaged
measurements. Instantaneous power draws may be substantially higher than the average.
Total energy usage
It is sometimes helpful to calculate the total All-In-One energy usage. Since power
consumption claims are provided in power units of Watts, the power consumption should be
multiplied by the time the All-In-One spends in each mode in order to calculate energy usage.
The total All-In-One energy usage is the sum of each mode's energy usage.
