Setting the Print Head Height to Suit Unevenness on the Print Surface

When printing on objects that easily come loose due to poor suction, or if the print surface is slightly uneven, resulting in a height difference between the detected and actual print surface height, adjust the height of the print heads so that they do not come into contact with the object to be printed on.

When printing on objects with low unevenness, select the print head height from "LOW" or "HIGH". Normally move the height-adjustment lever to "LOW". When printing on objects with higher unevenness, use "HIGH". The printing quality degrades as the distance between the print surface and the print heads increases. Do not move the height-adjustment lever to "HIGH" needlessly.

Select "SpLOW" when printing on a flat object with a high degree of parallelism between the contact surface and the print surface as well as minimal unevenness on the print surface.
