The indicator for [The amount of Pin usage] in MPX-
90M Head Manager shows how much the marking
pin has been used. The following cases need head
replacement.
The indicator is shown in red.
Though the indicator is not shown in red,
attractive printing is unavailable or images
are uneven.
The worn-out of marking pin is not the only rea-
son for decrease of print quality and uneven print
results. Refer to the pages below to find the cause
of the problem. If the worn-out of marking pin can
be the cause of the problem, replace the head with
a new one.
P. 69, "The printed image is unattractive," p. 69, "The
image is uneven"
The amount of pin usage is indicated in this window.
The level indicator increases little by little as the pin
is used to strike the material. The rate of increase
varies depending on the material used for printing.
