Safety Precautions
Do not carry the printer in a briefcase or handbag with loose, small
metal objects (such as fasteners or jewelry). Loose objects could
enter the paper output slot and damage the printer or cause a
malfunction.
Use the printer in a clean location that is free of dust and smoke.
Do not leave the printer unattended on top of a table or desk.
Always keep the top cover closed, and when the printer is not in
use, store it in a drawer or other safe location to prevent foreign
objects from entering the printer.
To avoid damaging delicate cable connectors and connection
points on the printer, always disconnect the USB interface cable
and the AC adapter power cable before you move or transport the
printer.
After you reach your travel destination, always use or store the
printer on a flat surface. Do not store or attempt to use the printer
with it standing on end or positioned at an odd angle. Do not
attempt to hold it in your hand while it is printing.
