Safety

Your printer has been carefully designed to give you years of safe, reliable performance. As with all electrical equipment, there are a few basic precautions you should take to avoid hurting yourself or damaging the printer:

•Read the setup and operating instructions carefully. Be sure to save them 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 in 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. 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, 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 are not sure, check with your dealer or with your local power company.

•Your printer has a earthed, 3-pin plug as a safety feature, and it will only fit into a earthed outlet. If you can not plug it in, chances are that you have an older, non-earthed outlet; contact an electrician to have it replaced with a earthed outlet. Do not use an adapter to defeat the earthing.

•The outlet into which you plug your printer must remain easily accessible at all times.

•To avoid damaging the power cable, do not put anything on it or place it where it will be walked on. If the cable becomes damaged or frayed, replace it immediately.

•If you are using an extension cable 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
