!IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY 1. Before disassembling or assembling parts of the printer and peripherals, make sure that the printer power cord is unplugged. 2. The wall outlet should be near the printer and easily accessible. 3. If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components. 4. The printer drives some of its components when it completes the warm-up period. Be careful to keep hands away from the mechanical and electrical components as the printer starts operation. 5. The inside and the metal parts of the fusing unit become extremely hot while the printer is operating. Be careful to avoid touching those components with your bare hands.
