2) Reserve adequate space around the printer so that convenient
operation and maintenance can be performed;
3) Keep the printer far away from water source, and do not expose
the printer to direct sunlight, strong light and heat;
4) Do not use or store the printer in a place exposed to high
temperature, high humidity or serious pollution;
5) Do not place the printer in a place exposed to vibration or
impact;
6) No condensation is allowed to the printer. In case of such
