Ricoh Gen4 Printhead (MH2420) Description

Outstanding Durability and Extended Service Life
Ricoh’s inkjet print heads are crafted from stainless steel, offering superior robustness and excellent anti-corrosion properties across multiple ink types. This ensures outstanding durability and a prolonged service life.

Versatile Ink Support
Equipped with a built-in heater, these heads can efficiently jet high-viscosity inks. Additionally, the isolated ink path ensures that the ink does not come into contact with the actuator (piezo elements).

Variable Drop Volume Capability
The multi-drop feature enables the creation of various drop sizes, facilitating high-quality grayscale printing.
