Ricoh GEN4 MH2420 Printhead
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).
