Part 5 Troubleshooting

Machining is performed, but marking is not possible.

What to check

Remedy

Is the workpiece loaded at the
correct location?

If empty marking is being performed at a location other than where the workpiece
is loaded, reload the workpiece.

Does the workpiece to mark meet
the "Conditions for materials that
can be marked"?

See "Getting Ready to Perform Marking" and prepare a workpiece that can be
marked.

Images are unattractive -- faint (images are dim).

What to check

Remedy

Are the workpiece settings for the
Metaza driver correct?

Choose the composition of the loaded workpiece.
Even if the material is the same, the hardness of the marking surface may vary
greatly depending on the casting method, the composition of impurities, the
presence of plating, and so on. In such cases, perform fine adjustment of the
marking force.

The image is uniformly dim.

Perform marking while increasing the brightness of [Gamma] or [Brightness] for
the Metaza driver a little at a time.
At this time, leave the workpiece loaded and perform overstriking at the same
location. Change the driver settings and continue marking until you obtain the
darkness you want.

White is reproduced, but grayscale
tones are faint.

Choose a custom workpiece (settings A through E), and adjust the marking force.
Perform marking while leaving the value for [Impact--MAX] unchanged and
increasing the value for [Impact--MIN] a little at a time.
At this time, leave the workpiece loaded and perform overstriking at the same
location. Change the driver settings and continue marking until you obtain the
darkness you want.

Important!

The various setting values determined with overstriking are effective only when
performing overstriking. The same results are not necessarily obtained when
marking is performed with a new workpiece under identical conditions.

Images are unattractive -- dark (all images are whitish).
