3.5.4 Print Duty
When you dont't use the head temperature sensor circuit, you can print under the maximum print
ratio N as shown in Figure 3-9. No matter what pattern you may use, set the maximum print ratio
under N. Even if you set the maximum print ratio over N, the printer prints, but it gives to printer
the possible damage. However, when the head temperature sensor circuit is activated and the print
ratio is over this maximum ratio, the printer stops printing.

When you print by using the wires evenly, the print duty of the continuous print is curved as shown
in Figure 3-9. The possible dot number D of a character is calculated by the numerical formula.

When you use the specific wires many times, make sure the maximum print ratio is not over the
print duty shown in Figure 3-10. However, when the head temperature sensor circuit is activated,
and the print using 5 or more specific wires is over this maximum ratio, the printer stops printing.
