This head is capable of jetting a variety of ink types in large droplet sizes. Please choose from two models to suit your application: Multi-drop 15-45pl (MH2620) or 27-54 pl (MH2820)
The built-in heater heats the ink to up to 80ºC for jetting, providing support for high-viscosity inks.
The multi-drop capability allows the creation of a range of drop sizes enabling grey-scale printing.
Ricoh 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.
Inkjet head with support for droplet enlargement and high-viscosity inks
Choose from two models to suit your application with droplet volumes of 15-45pl and 27-54pl.
