Disconnect power before removing the power supply shield or replacing components. Do not wear jewelry: Remove jewelry prior to servicing. Rings, necklaces and other metallic objects could come into contact with dangerous voltages and currents. Power source: This product is intended to operate from a power source that will not apply more then 264 volts rms for a 220 volt AC outlet or 140 volts rms for a 110 volt AC outlet between the supply conductors or between either supply conductor and ground. A protective ground connection by way of the grounding conductor in the power cord is essential for safe operation. Warning Labels Read and obey all posted warning labels. Warning labels are displayed on potentially dangerous printer components. As you service the printer, check to make certain that all warning labels remain in place.
