Ricoh Gen5 MH5420 J36002 Printhead Overview
The Ricoh Gen5 MH5420 is a genuine, Japanese-made industrial piezo printhead, and this version is built specifically for water-based (aqueous) inks. It is identified by the current Ricoh part number J36002, which replaces the earlier code N221414P — the two refer to the same short-cable aqueous head, so if your machine’s documentation lists the older N221414P, this is its direct successor. The 248mm cable assembly keeps the wiring compact, making it well suited to printers where the head sits close to the drive board.
Because it is engineered for aqueous chemistry rather than UV or solvent inks, this head is a natural fit for water-based production such as textile and soft-signage printing, where vivid colour and fine detail on fabric and flexible media matter most. It carries 1,280 nozzles and prints at a native 600 dpi, with variable grayscale dropping from 7 to 35 picoliters (7pl native) for smooth tonal transitions and sharp edges. A jetting frequency of up to 60 kHz supports fast throughput, while the integrated heater and thermistor hold ink viscosity steady so output stays consistent across long runs.
The Gen5 platform is built to last. Its stainless-steel body, nickel-alloy internals, and coated stainless-steel nozzle plate give it strong resistance to wear and corrosion, helping prevent clogging and extend service life — each nozzle is rated for up to 100 billion firing cycles. As an original Ricoh part, the J36002 is supplied in its sealed box with a unique serial number and is backed by the manufacturer’s warranty. It typically ships with removable hose-barb ink inlets, so it can be integrated into different aqueous ink-delivery systems with ease.
