Power Safety Precautions
Power Source
For 110 VAC printers, do not apply more than 140 volts RMS between the supply conductors
or between either supply conductor and ground. Use only the specified power cord and
connector. For 220 VAC printers, do not apply more than 264 volts RMS between the supply
conductors or between either supply conductor and ground. Use only the specified power
cord. This manual assumes that the reader is a qualified service technician.
Plug the three-wire power cord (with grounding prong) into a grounded AC outlet only. If
necessary, contact a licensed electrician to install a properly grounded outlet. If the product
loses its ground connection, contact with conductive parts may cause an electrical shock.
Disconnecting Power
Turning the power off using the On/Off switch does not completely de-engergize the printer.
You must also disconnect the printer power cord from the AC outlet. Position the power cord
so that it is easily accessible during servicing so that you may power down the printer during
an emergency.
Disconnect the power plug by pulling the plug, not the cord.
Disconnect the power cord in the following cases:
■ if the power cord or plug is frayed or otherwise damaged,
■ if any liquid or foreign material is spilled into the case,
■ if the printer is exposed to any excess moisture,
■ if the printer is dropped or damaged,
■ if you suspect that the product needs servicing or repair,
■ whenever you clean the product.
