Important Points to Check before Printing

Three Important Points (Measures for UV Reflected Light and
Ink Mist)
On this machine, ink affixed on the surface of the print heads might be cured by the reflection of the UV-LED
lamp light and by ink mist (ink splashing during printing) . If ink affixed on the surface of the print heads is
cured, dot drop-outs may occur . Continued use of the product in this state may cause a failure that requires
the replacement of the print heads .
While daily cleaning is important to prevent dot drop-outs, there are also three important points to check
before printing . Be sure to check the three points given below .
1 . You cannot use an object that easily reflects light as the object to be printed
on (the media) .
Materials that are likely to reflect the UV-LED lamp light, such as mirrors and stainless steel, promote the
curing of the surface of the print heads and therefore cannot be used as the object to be printed on (the
media) .
2 . Make the distance between the surface of the object to be printed on (the
media) and the print heads as short as possible .
As the distance between the surface of the object to be printed on (the media) and the print heads increases,
the likelihood of ink mist increases . When setting the height of the media manually, make the distance as
short as possible . When the height is automatically set, the distance is about 1 mm (39 .4 mil) .
