Electrical Characteristics

Operating voltage
Current consumption
(24V, 25°C, standard
print density)
If printing is continuously performed with a high ratio, the overcurrent protection may be
activated and result in uneven print density or a low voltage error. Therefore, the printing
length must not exceed the following values when printing with high print ratio.
Print ratio: Number of dots being energized per one dot line/Total number of dots per one
