3.1 Connecting the AC Power Cord
1. Turn off the printer power.
2. ●For AC power type (with built-in power supply), connect the AC power
cord to the AC inlet at the back of the printer and plug the AC power cord
into the wall outlet.
●For DC power type, connect the AC adapter cable connector to the power
connector at the back of the printer with its flat surface facing interface
connector side. Then connect the AC power cord to the AC inlet of the AC
adapter and then plug the AC power cord to the wall outlet.
CAUTION!
■Use only the specified AC adapter with the printer.
■When disconnecting a cable, DO NOT pull out by the cable. Always hold the plug.
■Always keep the AC power supply away from other noise generating equipment.
■DO NOT pull the AC power cord. Otherwise fire, electric shock, or power disconnection
may result.
■If lightning is approaching, unplug the AC power cord from the wall outlet. Otherwise
fire or electric shock may result.
■Keep the power cord away from heat generating appliances. Otherwise the shield of
power cord may be fused resulting in a fire or electric shock.
