Electrical Characteristics
Operating voltage
DC 24V ± 7%
Current consumption
(24V, 25°C, standard
print density)
Standby
Mean: Approximately 0.1 A
Operating
Mean: 1.8 A (M267A), 1.5 A (M267D, M267E)
Note: When print ratio is approximately 18%
Continuous printing for 50 lines (repeating 20H-7FH)
Font A, 48 columns, ASCII character
5 line feeding
Autocutting
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
dot line (576 dots)
Print ratio
80%
