Ricoh GEN5 Variant Guide — MH5420 UV vs MH5421 Water vs MH5421F
| Model | Ink Type | Colours | Key Use |

The MH5420 and MH5421 share identical physical dimensions and 7pl/60kHz specifications but are optimised for different ink chemistries. The MH5420 handles 4 UV/solvent colour channels; the MH5421 handles 2 water-based channels. The MH5421F adds recirculation for demanding single-pass applications. They are not interchangeable — always confirm your printer's specified model and ink system.
Cable Length — 248mm vs 500mm

Frequently Asked Questions
What is the difference between MH5420 and MH5421?
The MH5420 is optimised for UV-curable and solvent inks, supporting up to 4 colour channels. The MH5421 is optimised for water-based inks with up to 2 colour channels. Both share the same 7pl, 60kHz, 1,280-nozzle specs and identical physical dimensions. They are not interchangeable — always confirm your printer's ink system before ordering.
What Ricoh part code is the MH5420 248mm?
The MH5420 with 248mm total length carries Ricoh code N221414J. The same head in a 500mm total-length configuration uses a different Ricoh code. Always specify cable length when ordering to ensure you receive the correct version for your printer.
Is the MH5420 compatible with both UV and solvent inks?
Yes — the MH5420 is designed for UV-curable and solvent-based inks. It is not recommended for water-based inks — use the MH5421 for water-based applications. Always verify ink compatibility with your printer manufacturer's specifications.
What printers use the Ricoh GEN5 MH5420?
The MH5420 is used in Agfa Jeti Mira, Jeti Tauro and Jeti Titan series, CET Color Q5-1000, Akad NovaJet UV M6, Docan UV series, and Handtop HT UV series printers. Contact our team with your specific model to confirm cable length requirements before ordering.
