Ricoh Gen5 MH5420 (CABLE:650mm )PRINTHEAD N221414E

The Ricoh Gen5 MH5420 is a genuine, Japanese-built industrial piezo printhead designed for high-output digital printing. This particular configuration carries the longest standard signal cable in the MH5420 range — 650mm — and is identified by the Ricoh part number N221414E. The extended cable is what sets this version apart: it is intended for machines where the printhead sits a long way from the control board, such as wide-gantry flatbeds and large-format carriages that need extra signal reach. If your printer was originally fitted with a 650mm head, a shorter-cable version will not physically reach, which is why matching the exact length matters.

Engineered for UV-curable and solvent inks, the head packs 1,280 nozzles and prints at a native 600 dpi. Variable grayscale lets each nozzle lay down droplets ranging from 7 to 35 picoliters (7pl native), producing crisp text and smooth gradients alike. With a jetting frequency reaching 60 kHz, it keeps pace with fast production schedules, while a built-in heater and thermistor regulate ink temperature so jetting stays stable from the first pass to the last.

The Gen5 platform is known for its toughness. A stainless-steel body, nickel-alloy internals, and a coated stainless-steel nozzle plate resist the aggressive resins and photoinitiators in UV inks — a key reason these heads stay clog-free and deliver a long working life, with every nozzle rated for up to 100 billion firing cycles. As an original Ricoh component, the MH5420 ships backed by the manufacturer’s warranty, and it is widely deployed across UV flatbed, roll-to-roll, and solvent wide-format systems from brands including Agfa, Handtop, Docan, Flora, and CET Color.
