Konica Minolta KM800 printhead
KM800 Series printheads are:
- Thin film piezo with a unique nozzle processing technology that enables satellite-less, high-quality printing even with wide media gaps. Prints on uneven substrates and 3-dimensional objects, as well as jetting horizontally.
- Available with stainless steel ink flow path and nozzle plate, together with high jetting stability and nozzle durability ensures the print head meets the high reliability requirement for most industrial applications.
