Characteristic Specification
Primary line voltages 87 to 128 VAC (115 VAC nominal)
174 to 250 VAC (220 VAC nominal)
Input voltage range is switch-selectable.
Primary voltage
frequency range
47 to 63 Hz
Power consumption 235 watts at idle. (800 BTUs/hour) – Power consumption for
the printer will be somewhat higher due to image processor
electronics which draw power from the print engine.
Current rating 115 VAC configuration – 7 amp max./1 amp min.
220 VAC configuration – 7 amp max./1 amp min.
Primary voltage fusing 115 VAC configuration – 5 amp
