Read and obey all posted warning labels. Throughout the printer, warning

printer, check to make certain that all warning labels remain in place.
Power Safety Precautions
Power Source
For 115 VAC printers, do not apply more than 135 volts RMS between the
supply conductors or between either supply conductor and ground. For 230
VAC printers, do not apply more than 254 volts RMS between the supply
conductors or between either supply conductor and ground. Use only the
specified power cord and connector. 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. A protective ground
connection by way of the grounding conductor in the power cord is essential
for safe operation.

The power switch does not completely de-energize the printer. You must
also disconnect the power cord from the printer’s AC inlet. Disconnect the
power cord 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 product,
■ 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.
Use caution (or draws attention to a particular component). Refer
to the manual(s) for information.
Hot surface on or in the printer. Use caution to avoid personal
injury.
