Idling	34 dBA

Energy consumption

The following table documents the power consumption characteristics of the printer

Mode	Description	Power consumption
Printing	Printer is generating hard copy output	350 W
Power Saver	Printer is in energy saving mode	15 W for C520 and C522
		17 W for C524
		16 W for C522
		18 W for C524 network models and C524 duplex network
		model

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.

	Maximum Voltage
Nominal Voltage Range	Range
100V–110V AC	90V–117V AC
110V–127V AC	99V–134V AC
220V–240V AC	198V–254V AC

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.
