Stainless steel print head with flow through functionality and enhanced jetting reliability
The flow through functionality of this series of stainless steel printheads enables:
- Improved handling of heavily loaded pigment inks
- Increased reliability for single pass applications
- Greater fluid temperature control
- Improved nozzle up-time performance
- Reduced printer maintenance frequency
Variable drop volume capability:
The multi-drop capability allows the creation of a range of drop
sizes enabling grey-scale printing.
Excellent durability and extended service life
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.
Support for different inks
With its built-in heater, this print head is capable of jetting high-viscosity inks. Additionally, the ink path is isolated from the actuator (piezo elements) , i.e. no ink contact.
