6-1 What to Do If
The machine doesn't run even when printing data is sent.
Is the power switched on?
Make sure the Power/Movement button light is on. If it is
dark, press the Power/Movement button to switch on the
power.
Is the power cord connected correctly?
If it is not connected correctly, refer to the page indicated
below and connect it properly.
p 18 "Connecting the Power Cord"
Is the cable used for the connection to the computer
connected correctly?
If it is not connected correctly, refer to the page indicated
below and connect it properly.
p 19 "Connecting to the Computer"
Striking is performed, but nothing is printed.
Has the height of the head been adjusted to match
the thickness of the material?
Check whether the head is at a height that matches the thick-
ness of the material and whether the head is fixed in place
at that height. Printing cannot be performed if the height of
the head doesn't match the thickness of the material. Align
the head height and fix the head in place securely using the
knob.
Is the material loaded at the correct location?
If empty printing is being performed at a location other than
where the material is loaded, then reload the material.
Is the material to be printed in line with the param-
eters for printable material?
Prepare and use printable material.
p 28 "Preparing Material to Print"
Was printing performed at a location such as the
edge of the material?
Printing at the edge of material may bend or break the mark-
ing pin. If nothing is printed, the marking pin may be bent
or broken. Printing cannot be performed if the marking pin
is bent or broken. Change the pin.
p 67 "Changing the Pin Used for Marking"
The image is unattractive.
Are the settings for the material in the driver's set-
ting window correct?
Choose the composition of the loaded material.
Even if the composition of the material is the same, the
hardness of the printed 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 striking force to match the material.
p 72 "Adjusting the Striking Force to Match the Material"
Is the image printed clearly?
If the image is not printed clearly, adjust the brightness of
the image. Perform printing while increasing the brightness
of [Gamma] or [Brightness] in the driver's setting window a
little at a time.
At this time, leave the material loaded and perform
overstriking at the same location. Continue changing set-
tings and performing printing until you obtain the darkness
you want.
p 57 "A Wide Variety Settings You Can Make with the Driver"
Are grayscale tones printed clearly?
If the grayscale tones is not printed clearly, adjust the force
of striking. Perform printing while leaving the value for [Im-
pact--MAX] unchanged and increasing the value for [Im-
pact--MIN] a little at a time.
At this time, leave the material loaded and perform
overstriking at the same location. Continue changing the
settings in the driver's setting window and performing print-
ing until you obtain the darkness you want.
p 57 "A Wide Variety Settings You Can Make with the Driver"
More Information about Overstriking
The various setting values determined with overstriking are
effective only when performing overstriking under identi-
cal conditions. The same results are not necessarily obtained
when printing is performed with a new piece of material
with only the conditions made the same, without perform-
ing overstriking.
Is the marking pin worn?
Attractive printing may be impossible if the marking pin
becomes worn.
Adjust the pin or change it to a new one.
p 66 "5-2 Maintenance of the Marking Pins"
The image is uneven.
Is the printed surface slightly uneven?
Replace with material having a level printing surface.
p 28 "Preparing Material to Print"
Is the printed surface at an angle?
Replace with material having a level printing surface.
p 28 "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 perform-
ing overstriking with different settings for [Gamma], [Bright-
