Oki 521, 520 manual

•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 exten-sion’s rating. Generally, the total ratings of all equipment plugged into any one power line should not exceed 15 amps. Don’t exceed this unless you know that the power line your equipment is plugged into has a rating above 15 amps.

•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. the Warranty, Regulatory, and Safety Information booklet supplied with your printer explains how to get your printer serviced by qualified Okidata technicians.

•If anything happens that indicates that your printer is not working properly or has been damaged, unplug it imme-diately and follow the procedures in the Warranty, Regulatory, and Safety Information booklet supplied with your printer for having your printer serviced.

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.
