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.
Disconnecting Power
WARNING:
Turning the power Off using the power switch does not completely de-energize the
printer. You must also disconnect the Power Cord from the printer's Alternating Current (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 cleaning, servicing or repair,
Electrostatic Discharge (ESD) Precautions
Some semiconductor components, and the respective sub-assemblies that contain them, are
vulnerable to damage by Electrostatic Discharge (ESD). These components include Integrated Circuits
(ICs), Large-Scale Integrated circuits (LSIs), field-effect transistors, and other semiconductor chip
components. The following techniques will reduce the occurrence of component damage caused by
static electricity.
Be sure the power is Off and observe these other safety precautions.
•
Immediately before handling any semiconductor component assemblies, drain the electrostatic
charge from your body. This can be accomplished by touching an earth ground source or by
wearing a wrist strap device connected to an earth ground source. Wearing a wrist strap will also
prevent accumulation of additional bodily static charges. Be sure to remove the wrist strap before
applying power to the unit under test to avoid potential shock.
