Similarly, avoid arranging boards on the table with gaps. Leaving gaps between boards will
result in UV light reflecting back into the print head and causing nozzle blockages. Sacrificial

Note: Sacrificial material should be the same thickness as the board to be printed. Thicker
material might strike the carriage whereas thinner material will allow UV light to reflect back
into the print heads.
