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 nd 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.

image is uneven"
