Ricoh has announced the launch of two new Industrial Inkjet Printheads – the Ricoh MH5421F and the Ricoh MH5421MF. The OEM will start taking orders for both beginning today. The printheads were designed for both low-viscosity (6 mPas) and medium-viscosity fluids (11 mPas) respectively. They enable highly stable jetting performance by utilizing an ink recirculating structure. This structure enables continuous ink flow directly behind the nozzle, reducing the risk of jetting failure caused by either clogged ink or trapped air bubbles. Each printhead has enhanced bonding technology for improved durability. With these new features, the Ricoh MH5421 MF and MH5421F printheads offer enhanced compatibility with a wider range of fluids.

Ricoh added that these features result in: increased reliability for single-pass printing by delivering improved print quality and productivity; increased reliability for systems with rapid-setting ink, such as pigment ink, white or metallic materials; increased reliability for systems with fast-drying inks; and the removal of air bubbles in the ink chamber to achieve self-recovery from jetting failure.

In the industrial printing market for textiles, labels, packaging and ceramic tiles, there’s an increasing requirement to meet a wide variety of customer needs such as smaller lot sizes and shorter delivery times, said the OEM. This requires the rapid digitization of industrial printing in order to deliver greater flexibility and productivity, resulting in increased demand for printheads that deliver finer image quality as well as high productivity and greater reliability. “The Ricoh MH5421 F and Ricoh MH5421MF offer high-resolution printing to support its industrial partners and customers to meet these market needs,” said the company.
