Power Safety Precautions Power Source For 115 VAC printers, do not apply more than 135 volts RMS between the supply conductors or between either supply conductor and ground. For 230 VAC printers, do not apply more than 254 volts RMS between the supply conductors or between either supply conductor and ground. Use only the specified power cord and connector. This manual assumes that the reader is a qualified service technician. Plug the three-wire power cord (with grounding prong) into a grounded AC outlet only. If necessary, contact a licensed electrician to install a properly grounded outlet. If the product loses its ground connection, contact with conductive parts may cause an electrical shock. A protective ground connection by way of the grounding conductor in the power cord is essential for safe operation. Disconnecting Power Warning The power switch does not completely de-energize the printer. You must also disconnect the power cord from the printer's AC inlet. Disconnect the power cord by pulling the plug, not the cord. Disconnect the power cord in the following cases: ■ if the power cord or plug is frayed or otherwise damaged, ■ if any liquid or foreign material is spilled into the product, ■ if the printer is exposed to any excess moisture, ■ if the printer is dropped or damaged, ■ if you suspect that the product needs servicing or repair, ■ whenever you clean the product. iv Phaser 8400/8500/8550/8560 Color Printer Service Manual
