Description
The RICOH MH5442 is the next generation of high-performance industrial inkjet printheads, building on the proven MH5440 and MH5441 family. Designed for applications requiring both high print quality and high productivity, this 4-color printhead combines advanced jetting technology with robust construction to meet the demands of industrial printing environments.
Key Features
- High print quality & productivity: 1,280 nozzles in 4 x 150npi rows, native 7pl droplet, enhanced jetting accuracy and velocity, and 30kHz max frequency in 4-level grey-scale mode.
- Enhanced ink compatibility: Works with UV, Solvent, Aqueous, and other inks — with aqueous ink service life more than double that of the MH5421/MH5441 series (per Ricoh test procedures).
- Enhanced non-wet coating: Durable nozzle surface for continued robust printing and maintenance (per Ricoh test procedures).
- System compatibility: Straightforward surface-based alignment for high precision positioning, detachable I/O cable design, and 4-color capability.
