Ricoh’s inkjet print heads are made of stainless steel.These heads are highly robust and offer excellent anti-corrosion properties for multiple inks, resulting in excellent durability and extended service life.
With its built-in heater, these heads are capable of jetting high-viscosity inks. Additionally, the ink path is isolated from the actuator (piezo elements) , i.e. no ink contact.
The multi-drop capability allows the creation of a range of drop sizes enabling grey-scale printing.
