5-6 Head Replacement
The Replacement Cycle for the Head
MPX-90 Head Manager shows the amount of pin usage.
If the indicator for the pin you're using is red, then replace it with a new head. If attractive printing is impossible
or printed images are uneven even though the scale is not red, then change to a new head.
P. 91, "Adjusting the Striking Force of the Pin," p. 105, "The printed image is unattractive," p. 106, "The image is
uneven"
