Ricoh GH2220 Printhead

Ricoh GH2220 Printhead

Features:

Expanding industrial opportunities with new precision manufactured silicon range.

The result of over 10 years of Ricoh research and manufacturing optimisation, the GH printhead is now available for OEMs to integrate into their water and solvent ink-based printer offerings.

Supports water and solvent based inks.

In addition to water-based inks, these printheads also support solvent-based inks.

Multi-drop technology enables greyscale printing.

These printheads support multi-drop droplet control, which instantly consolidates ink exiting the nozzle at high speed before it reaches the surface of the media. Droplet volume control allows full control of ink ejection from small to large droplets.
