•Unplug the printer before you clean it. Use only a damp cloth. Do not use liquid or aerosol cleaners.

•To protect your printer from overheating, make sure no openings on the printer are blocked. Do not put the printer on or near a heat source, such as a radiator or heat register. If you put the printer in any kind of enclosure, make sure it is well ventilated.

•The printhead can get quite hot when it has been printing for a length of time. Do not touch the printhead until it has had a chance to cool off.

•Do not use your printer near water. Do not spill liquid of any kind into it.

•Do not poke anything into the ventilation slots on the sides of the printer. You could get a shock or cause a fire.

•If anything happens that indicates that your printer is not working properly or has been damaged, unplug it immediately. Then, follow the procedures in “Service and Support” for having your printer serviced.
