[For UJF-3042 / UJF-3042FX]

Note that, when using thin substrates (such as paper or film), the marks of vacuum holes on the board surface may remain after printing. Be sure to perform a prior test on substrates before using it.

[For UJF-3042HG]

When you print on thin substrates (such as paper or film), install the accompanying vacuum table and the table spacers, and adjust the height of the table to achieve a head gap of 1.5mm(recommended value). In addition, note that the marks of vacuum holes on the board surface may remain after printing. Be sure to perform a prior test on substrate before using it.
