Important Safety Instructions

Before using your Epson printer, read and follow these safety instructions:
■Be sure to follow all warnings and instructions marked on your Epson printer.
■Use only the type of power source indicated on the printer label.
■Use only the power cord that comes with the printer. Use of another cord may cause
fires or shock. Do not use the cord with any other equipment.
■Place the printer near a wall outlet where the plug can be easily unplugged.
■If you won’t be using the printer for a long period, unplug the power cord from the
electrical outlet.
■Always turn off the printer using the POn button, and wait until the POn light
stops flashing before unplugging the printer or cutting off power to the electrical
outlet.
■Avoid plugging the printer into an outlet on the same circuit as a photo copier or air
control system that regularly switches on and off, or on an outlet controlled by a wall
switch or timer.
■Do not let the power cord become damaged or frayed.
■If you use an extension cord with the printer, make sure the total ampere rating of the
devices plugged into the extension cord does not exceed the cord’s ampere rating.
Also, make sure the total ampere rating of all devices plugged into the wall outlet does
not exceed the wall outlet’s ampere rating.
■Avoid locations that are subject to rapid changes in heat or humidity, shocks or
vibrations, or dust.
■Leave enough room around the printer for sufficient ventilation. Do not block or
cover openings in the case or insert objects through the slots.
■Do not place the printer near a radiator or heating vent or in direct sunlight.
■Place the printer on a flat, stable surface that extends beyond its base in all directions.
It will not operate properly if it is tilted or at an angle.
■Make sure the back of the printer is at least 4 inches (10 cm) away from the wall.
■Do not open the scanner section while the NX420 Series is copying, printing, or
scanning.
■Do not spill liquid on the printer.
