Ricoh launches next generation industrial inkjet printheads

IndPrint

Ricoh has announced the launch of two new industrial inkjet printheads: the MH5421F and the MH5421MF. The company will start taking orders for both of these printheads from June 2017.

The printheads were designed for both low viscosity (6 mPas) and medium viscosity fluids (11 mPas) respectively. They enable highly stable jetting performance through the incorporation of 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 entrapped air bubbles. Each printhead has enhanced bonding technology for improved durability. With these new features, the printheads offer enhanced compatibility with a wider range of fluids.

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 ink, and the removal of air bubbles in the ink chamber to achieve self recovery from jetting failure.

In the Industrial print market there is an increasing need to meet a wide variety of customer needs such as smaller lot sizes and shorter delivery times. This requires the rapid digitisation 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 MH5421 F and MH5421MF offer high resolution printing to support its industrial partners and customers to meet these market needs.
