2.2 Adjusting Print Head Height
Adjust the print head height to suit media thickness.
• The print head height can be adjusted to one of three settings to suit the requirements.
Range Gap between print head and platen
Low 2 mm (default setting)
Middle 2.5 mm
High 3 mm
• The print head height should normally be set to 2.0 mm. If the gap exceeds 2.5 mm, the ink
droplets may vaporize before reaching the media. Vaporized ink will adhere to the print head
nozzle surface and cooling fan filter. The amount of reflected light incident on the print head
surface from the UV-LED unit will also increase. Reflected light may cure vaporized ink adhering
to the nozzle surface. This will increase viscosity, reduce print quality, and generate print head
faults.
