2.5pl drop size allows excellent print quality without graininess.With 1,280 nozzles configured in 4 x 150dpi rows, this head achieves high-resolution 600dpi printing. Additionally, the ink paths are isolated, enabling a single head to jet up to two ink colors.
Achieves excellent gray-scale rendering at up to 4 levels.
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.
Ricoh's open waveform policy allows tailored multi-drop printing of between 2.5 - 9pl, enabling high quality grayscale printing.
