Noise emission levels
The following measurements were made in accordance with ISO 7779 and reported in conformance with ISO 9296.
Energy consumption
The following table documents the power consumption characteristics of the printer
The power consumption levels listed in the previous table represent time-averaged measurements. Instantaneous power
draws may be substantially higher than the average.
Power regulation notice
Warning: Electrical surges can be very destructive to equipment connected to AC power sources. If you plan to
operate your printer at a voltage exceeding the voltage range(s) in the following table, you must attach
a suitably rated and certified power-regulating device (such as a voltage stabilizer or UPS device) to
the printer power supply. Your warranty may not cover damages caused by power surges.
Total energy usage
It is sometimes helpful to calculate the total printer energy usage. Since power consumption claims are provided in power
units of Watts, the power consumption should be multiplied by the time the printer spends in each mode in order to
calculate energy usage. The total printer energy usage is the sum of each mode's energy usage.
