Answer: Recommended speed mode is as follows:

720 X 900dpi 12pass / 1,440 X 1,200dpi 16pass is recommended.

[For LF-140 ink with UJF-3042FX / UJF-3042HG]

When using light colors with LF-140 ink, 1,440 X 1,200dpi 16pass is recommended.

* When using the IJ primer PR-100 with UJF-3042FX/UJF-3042HG, set the number
　of pass as 24 or more. In addition, set the density of primer as 30%
　(recommended density) in RasterLinkPro5.
