Attaching the Power Cord
§ Use a power supply that is the appropriate voltage and frequency: AC
120 V, 60 Hz 0.5A. This is the standard for an electrical outlet in the
United States or Canada.
§ Use only the power cord that came with the printer. Using a longer
cord or an extension cord may result in reduced voltage or
malfunctions.
§ If you smell a peculiar odor or see smoke, unplug the power cord
immediately.
§ Do not place anything in front of your wall outlet that may obstruct
your access to it or put pressure on the power cord.
