(*1): Voltage drop at maximum current may cause the print quality problem. Please check it carefully in your environment such as control board, wiring, etc. Also please keep the voltage within the speci? ed voltage range even by the voltage drop.

(*2): The number of diameter varies depending on the conditions.

(*3): Normal temperature at 25°C, normal humidity, 12.5% printing ratio, rated energy and by use of the recommended print paper.

(*4): Performance may be changed depending on the cutter equipped method.
