RICOH 2810f_2910f

Characteristics

Stainless steel print head with flow through functionality and enhanced jetting reliability

The flow through functionality of this series of stainless steel print
heads 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.

Print head with support for large drops and high-viscosity inks

Choose from two models to suit your application with drop volumes of 27-50pl and 50-90pl.
