Electrical specifications Review the power requirements and rated current for the printer. NOTE: Power requirements are based on the country/region where the printer is sold. The values in the following table are subject to change. CAUTION: Do not convert operating voltages. This can damage the printer and void the printer warranty. Table 1-16 Electrical specifications Specification 100-volt models Power requirements1 100 to 127V 50/60 Hz Rated current 10.0 amps 110-volt models 110 to 127V 50/60 Hz 10.0 amps 220-volt models 220 to 240V 50/60 Hz 5.0 amps 1 Power reported is highest value measured for all printer models using standard voltages. Acoustic emissions Review the acoustic emissions, including sound power level and sound pressure level. NOTE: Ensure the printer is installed in an area where the printer sound level will not disturb workers.
