Note:
1. Use the cable shielded within the length of 3m. If a cable longer than 30cm between the
power supply and printer, make sure to use a condenser to stabilize the power level. Use a
cable in smaller number than AWG#24.
2. The printer has no power switch. Locate a power switch on the supply side to switch the
printer on or off. Do not plug in and out to set the power on and off. Damage may be caused.
