Impact Force
Impact Force enables the striking force of the printhead pins to be
changed. Three selections are possible.
• Normal Auto: This is the default value. Impact force of the
printhead pins is adjusted automatically for paper thickness.
• High: This is the highest impact force and over rides the
Normal Auto selection. High pin force is used to obtain clearer
print on medium thickness forms. Leaving the printer in High
can damage the printhead, especially if printing on single sheet
forms.
• Normal 1P: Disables the automatic setting of the impact force.
Normal 1P is used to print in normal force when thicker print
media is used such as labels.
