Safety
WARNING: Do not push objects (including paper clips or staples) into slots or openings on the
printer. Making contact with a voltage point or shorting out a part could result in fire or electrical
shock.
WARNING: Do not remove the covers or guards that are fastened with screws unless you are
installing optional equipment and are specifically instructed to do so. Power should be Off when
performing these installations. Disconnect the power cord when removing the covers and guards
for installing optional equipment. Except for user-installable options, there are no parts that you
can maintain or service behind these covers.
The following are hazards to your safety:
• The power cord is damaged or frayed.
• Liquid is spilled into the printer.
• The printer is exposed to water.
If any of these conditions occur, do the following:
1. Turn Off the printer immediately.
2. Disconnect the power cord from the electrical outlet.
3. Call an authorized service representative.
Power Safety Precautions
Power Source
For 115 VAC printers, do not apply more than 127 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.
