2.5pl drop size allows excellent print quality without graininess.With 1,280 nozzles configured in 4 x 150dpi rows, this head achieves high-resolution 600dpi printing. Additionally, the ink paths are isolated, enabling a single head to jet up to two ink colors.

Support for grey-scale

Achieves excellent gray-scale rendering at up to 4 levels.

  • *Although controls for up to 4 scales are provided, actual jetting depends on ink characteristics.
