6-1 What to Do If
Chapter 6 Appendix
The image is always faint at the same location.
Is the height displacement for the printed sur-
face excessive?
If the image is always faint at the same location even
though you’re performing printing using a head cap,
the height displacement for the printed surface may
be excessive. Recheck the parameters of materials that
the machine can print and select material that meets
the parameters. Also, image quality is not assured when
printing photographic data on a curved surface with
this machine.

P. 33, "Preparing Material to Print"
Have you tried to adjust the levelness of the
machine?
If you’re not using a head cap If the image is often faint at
the same location, such as near the front right area of the
table, then adjusting the levelness of the machine may
improve the image quality. Please note that this is not ef-
fective when unevenness in the image is unrelated to the
printing location, such as when uneven areas vary from
one piece of material or image to another. We recom-
mend using a head cap whenever such use is possible.

P. 32, "Head Caps"
Procedure
1. Using an adhesive sheet, load a piece of
included test-use printing material at the center
of the table.
If the included material has been used up, then prepare
a piece of material that is larger than 60 mm (2.3 in.) and
has a smoothness of 0.05 mm (0.002 in.) or less. Make a
print without using the head cap.

2. Go into the [Printers] folder.
3. Right-click the [Roland MPX-90] and open the
setting screen for METAZA driver. Click [Printing
Preferences].
The setting window for METAZA driver appears.
4. Click the [Option] tab.
5. Click [Test print].
The test pattern is printed on the material.
6. Use the scale to read and note down loca-
tions where the test pattern is not continuous
or not visible.
Note down the values in all four directions (front, back,
left, and right).

The image is uneven.
Is the printed surface slightly uneven?
If no head cap is attached, then attach a head cap and
perform printing. If you’re using material that can be dam-
aged by printing with the head cap attached, then replace
it with material that has a level printing surface.

P. 32, "Head Caps," p.33, "Preparing Material to Print"
Is the printed surface at an angle?
If no head cap is attached, then attach a head cap and
perform printing. If you’re using material that can be dam-
aged by printing with the head cap attached, then replace
it with material that has a level printing surface.

P. 32, "Head Caps," p.33, "Preparing Material to Print"
Is the image darkness uneven?
Performing overstriking with the material left loaded
at the same location may improve the image quality.
Try performing overstriking with different settings for
[Gamma], [Brightness], or [Contrast] in the driver's set-
ting window.

P. 75, "Checking the Finished Results in the Preview Win-
dow"
Was bidirectional printing performed?
Bidirectional printing can shorten the printing time, but
the image quality may suffer. If this happens, go to the
driver's setting window and clear the selection for [Bidi-
rection], then redo printing.

Is the marking pin worn?
Attractive printing may be impossible if the marking
pin becomes worn. Check the state of the marking pin.
If the marking pin becomes worn, replace the head with
a new one.
