As with all electrical equipment, however, there are a few basic precautions you should take to avoid hurting yourself or damaging the unit: • Read the setup and operation instructions in this manual carefully. Be sure to save it for future reference. • Read and follow all warning and instruction labels on the printer itself. • Unplug the printer before you clean it. Use only a damp cloth; do not use liquid or aerosol cleaners. • Place your printer on a firm, solid surface. If you put it on something unsteady, it might fall and be damaged; if you place it on a soft surface, such as a rug, sofa, or bed, the vents may be blocked, causing it to overheat. •To protect your printer from overheating, make sure no openings on the printer are blocked. Don’t 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. • Do not put anything into the ventilation slots on the sides of printer, you could get a shock or cause a fire. • The printhead can get quite hot when it has been printing for a length of time. Do not touch the printhead untill it has had a chance to cool off. • Do not use your printer near water, or spill liquid of any kind into it. • Be certain that your power source matches the rating listed on the back of the printer. If you’re not sure, check with your dealer or with your local power com- pany. •Your printer has a grounded plug as a safety feature, and it will only fit into a grounded outlet. If you can’t plug it in, chances are you have a non-grounded ontlet; contact an electrician to have it replaced with a grounded outlet. Do not use an adapter to defeat the grounding. •To avoid damaging the power cord, don’t put anything on it or place it where it will be walked on. If the cord becomes damaged or frayed, replace it immedi- ately. • If you’re using an extension cord or power strip with the printer, make sure that the total of the amperes required by all the equipment on the extension is less than the extension’s rating. Generally, the total ratings of all equipment plugged into any one power line should not exceed 15 amperes. Don’t exceed this unless you know that the power line your equipment is plugged into has a rating above 15 amperes. • Aside from the routine maintenance described in this handbook, don’t try to service the printer yourself; opening the cover may expose you to shocks or other hazards. Don’t make any adjustments other than those outlined in the manual – you might cause damage requiring extensive repair work. • If anything happens that indicates that your printer is not working properly or has been damaged, unplug it immediately and follow the procedures in Chap- ter 5. These are some of the things to look for: The power cord or plug is frayed or damaged. Liquid has been spilled into the housing, or the printer has been exposed to water. The printer has been dropped or its cabinet has been damaged. The printer doesn’t function normally when you’re following the operating instructions. • Screen jitter on your CRT may occur in an environment where the space be- tween your printer and CRT is narrow (200 mm or less). In such cases, open up the space. • Do not connect this product to an uninterruptible power supply (UPS).
