Note on printing with a high print ratio
If printing is continuously performed with a high print 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)
Maximum permissible printing length on print ratio
