Important points to check before printing
Four important points (measures for ink mist and UV reected light)
On this machine, ink axed on the surface of the print head might be cured by ink mist (ink splash upon
printing) and reection of the UV lamp light. If ink axed on the surface of the print head is cured, it might
cause dot drop-outs, and if you use the product without taking any measures, it might cause a failure which
requires replacement of the print head.
While daily cleaning is important to prevent dot drop-outs, there are also four important points to check before
printing. Be sure to check the four points given below:
1. You cannot use a object which reects light as a print object (media).
Mirrors and stainless materials, etc. which are likely to reect the UV lamp light promote curing of the surface
of the print head, and therefore they cannot be used as a print object (media).
2. Set the minimum required size as the print area*.
This machine exposes the UV lamp light to all the area specied as the print area. If the blank area (where ink
is not applied) in the print area is large, the reection of the UV lamp light becomes large, promoting curing
of the surface of the print head. Be sure to specify the minimum required size as the print area.
* This machine requires you to specify a rectangle area in the print object where you want to make a print as the
“print area”. For information on how to specify the print area, refer to
P. 17, "Choosing How to Specify the Print
Area", P. 17, "Specify the print area directly", and P. 19, "Specifying the Print Area from the Print Center Position".
The blank area in the print area is
minimized.
