Ricoh launches next generation industrial inkjet printheads

New series compatible with wider range of inks for faster, quality printing
Ricoh Europe, London, 19 October 2016 – Print innovators can boost quality and speed of inkjet application, thanks to a new series of industrial printheads from Ricoh.

The Ricoh MH5420 series feature proprietary bonding technology for improved durability, and are compatible with a wider variety of fluids. The extended compatibility means users can print with water-based, solvent or UV inks – enabling them to extend their offering.

The Ricoh MH5421LVF and Ricoh MH5421F printheads enable highly stable jetting performance through the introduction of a new recirculating structure, reducing the risk of jetting failure caused by clogged ink. Other benefits to this include:

• Increased reliability for single-pass systems to improve print quality and productivity
• Increased reliability for systems with rapid setting ink, such as white or metallic materials
• Removal of bubbles in the chamber to enable self-recovery from jetting failure

The first printhead in the series will be commercially available from January 2017.

Graham Kennedy, Head of Commercial Ink Jet Business, Ricoh Europe, said: “There is a rapidly growing demand in the industrial printing market across both mature and embryonic applications fuelled by a wide variety of customer needs.  Digitisation of industrial printing can deliver greater flexibility and productivity for these businesses, which is where Ricoh’s new MH5421 printhead series offers solutions to these needs.”
