RICOH MH5421F/5421MF

With 1,280 nozzles configured in 4x150dpi rows, this head achieves high-resolution 600dpi printing. Isolated ink paths enable a single printhead to jet up to two ink colors.
Additionally the printhead is provided in two viscosity formats (F/MF) for optimized fluid handling performance.

Highly stable jetting performance is achieved through the introduction of a new recirculating structure. This structure enables continuous ink flow resulting in 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 RICOH MH5421F and MH5421MF 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
• The removal of air bubbles in the ink chamber to achieve self-recovery from jetting failure

• *Single-pass system : the printhead carriage remains in a fixed position and completes image printing in a single pass while the print material is conveyed underneath.
