Important Points to Check before Printing
Three Important Points (Measures for UV Reected Light and
Ink Mist)
On this machine, ink axed on the surface of the print heads might be cured by the reection of the UV-LED
lamp light and by ink mist (ink splashing during printing). If ink axed 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 reects light as the object to be printed
on (the media).
Materials that are likely to reect 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).

""Setting the Height of the Media Manually" (P. 8)

Chapter 1 Fully Utilizing the Machine
3. A jig might be required depending on the size and shape of the object to be
printed on (the media).
Depending on the size and shape of the object to be printed on (the media), the distance between the
object to be printed on (the media) and the print heads may increase, which will increase the likelihood of
ink mist occurring. In the direction of print head movement, the object to be printed on (the media) or a jig
must be present in the area 40 mm (1.6 in.) to both the right and left of the portion (width) of the data to be
printed. In this situation, the dierence in height between the surfaces of the object to be printed on (the
media) and the jig must be less than 2 mm (78.7 mil).
""2. Setting the Height of the Media Automatically" (First Step Guide)
""Setting the Height of the Media Manually" (P. 8)
""Height Settings When the Print Surface is Uneven" (P. 9)
When a jig is required:
• The object to be printed on (the media) is not large enough to spread over the area 40 mm to both the right
and left of the portion (width) of the data to be printed.
• The variation in height of the surface of the object to be printed on (the media) is 2 mm or more.

There are conditions for the height settings when the surface of the object to be printed on (the media) has a

Manually set the height of the media for printing.
Although the manual setting takes a little longer than the automatic setting because you need to visually set
the height, it is suitable when you do not want the head gap sensor to come in contact with the media and
when you want to set the distance between the heads and the media.
* If the print surface is uneven, there is a limit to the area of unevenness.

Height Settings When the Print Surface is Uneven
This machine can also print on uneven surfaces. However, note the following points regarding the height
setting.
The gap between the "highest position of the media" and the "lowest position of
the print surface" should be 2 mm (78.7 mil) or less (as a general guide).
The print quality at the lower position degrades as the height gap widens.

Expanding the Distance between the Media and the Print
Heads
When you set the height of the media automatically (First Step Guide), the distance between the media and
the print heads is set to 1.0 mm (39.4 mil) with which optimum printing is performed. However, if the height
(thickness) of the media on which printing is performed varies or when the media is lifted or warped during
printing, the media might come into contact with the print heads.
You can expand the distance in advance considering the change of the height (thickness) of the media.
NOTE
• If the distance is expanded too much, the print quality may be deteriorated and the nozzles of the print
heads may be clogged. Congure the settings so that the distance between the highest position of the
media and the lowest position of the print surface is 2 mm or less (P.9).
• This setting is enabled when the height of the media is set automatically.

In the following cases, ink tends to collect on the surface of the heads. Under some conditions, this ink may
be transferred to the media or cause dot drop-out.

• When the ambient temperature is low.
• When the variation in the unevenness on the print surface is high (there is a limit to the unevenness of the

Reducing Print Quality Degradation from Ink Mist (Ink Spatter)
Under some conditions (such as low temperature or when a static charge is likely), a greater amount of ink
mist (ink spatter during printing) may be produced and adversely aect the print quality. In these cases, you
may be able to alleviate the symptom by lowering the rotation of the carriage fan.

Description
Whether the symptom can be alleviated depends on the temperature and media type. Be sure to check the
print status as you adjust the setting.
However, the purpose of the carriage fan is to prevent ink buildup on the print heads. Lowering its rotation
will lead to more dot drop-outs. This means, if you specify "MIDDLE," "LOW," or "OFF," you should perform
normal cleaning more frequently. The "PERIODIC CL." (P. 17) setting is also eective against dot drop-outs.
