RICOH announces two new industrial inkjet printheads

RICOH MH5421F and RICOH MH5421MF are two new industrial printheads from RICOH. Both the products are designed for low viscosity (6 mPas) and medium viscosity fluids (11 mPas) respectively. These printheads enable highly stable jetting performance through the incorporation of an ink re-circulating structure. The structure enables continuous ink flow directly behind the nozzle, reducing the risk of jetting failure caused by either clogged ink or entrapped air bubbles. Each printhead has enhanced bonding technology for improved durability. With these new features, RICOH MH5421 MF and MH5421F printheads offer enhanced compatibility with a wider range of fluids.

The added features of the two newly launched RICOH printheads are designed to result in increased reliability for single-pass printing by delivering improved print quality and productivity. Also, the products will able to increase reliability for systems with rapid setting ink, such as pigment ink, white or metallic materials. RICOH MH5421F and RICOH MH5421MF printheads can also increase reliability for systems with fast drying ink and removal of air bubbles in the ink chamber to achieve self-recovery from jetting failure.
