MH5440 vs MH5420 — The Key Difference
| Spec | MH5440 (this listing) | MH5420 |
|---|---|---|
| Colour channels | 4 colours | 2 colours |
| Ink ports | 4 × dual ports | 2 × dual ports |
| Nozzles / resolution / drop | Identical — 1,280 / 600dpi / 7pl | Identical — 1,280 / 600dpi / 7pl |
| Best for | Full CMYK or 4-ink systems in a single head | 2-colour systems, dual-channel configurations |
The MH5440 and MH5420 are physically identical and share the same print specifications — the only difference is the number of isolated ink paths. The MH5440's 4 × dual port configuration allows a single head to carry all four CMYK channels simultaneously, making it the preferred choice for compact printer designs where fewer heads are installed. Always confirm which model your printer specifies — they are not interchangeable at the printer channel level.
MH5440 vs MH5421 Water — Ink Type Comparison
| Model | Primary Ink Type | Colours | Typical Application |
|---|---|---|---|
| MH5440 (this listing) | UV / solvent / aqueous | 4 | UV flatbed, solvent wide-format, single-pass industrial |
| MH5421 Water | Water-based | 2 | Sublimation, dye-sub, aqueous textile printers |
| MH5421F | Water-based (enhanced) | 2 | Single-pass, pigment, white ink, fast-drying |
Compatible Systems
The Ricoh GEN5 MH5440 is a broad-application OEM industrial head used by system integrators across UV flatbed, UV roll-to-roll, solvent wide-format, textile, and single-pass printing platforms. It does not have a fixed compatible printer list — specification is determined at the OEM system level. Contact our team with your printer make, model, and firmware version to confirm MH5440 compatibility before ordering.

Frequently Asked Questions
What is the difference between MH5440 and MH5420?
The MH5440 is the 4-colour model — it has 4 × dual ink ports allowing a single head to carry all four CMYK channels simultaneously. The MH5420 is the 2-colour model with 2 × dual ports. Both share identical 1,280-nozzle, 600dpi, 7pl, 30kHz specifications and identical physical dimensions. The MH5440 is preferred for compact printer designs where fewer heads are installed. They are not interchangeable at the printer channel level.
How many colours can the MH5440 print simultaneously?
Up to 4 colours — the isolated ink paths within the MH5440 allow each of the 4 sets of 320 nozzles to carry an independent ink colour. This means a single MH5440 can handle full CMYK in one pass, making it efficient for systems designed around minimal head count.
What inks are compatible with the MH5440?
The MH5440 is compatible with UV-curable, solvent, aqueous, and other specialty inks within a viscosity range of 10–12 mPas and surface tension of 28–35 mN/m. The integrated heater supports operation up to 60°C for high-viscosity ink systems. Always verify your specific ink formulation against Ricoh's MH5440 datasheet before installation.
What is the total cable length of the MH5440?
The standard MH5440 has a total length of 248mm including cables and connectors. Contact our team if your printer requires a different cable length configuration.
Do you ship Ricoh GEN5 MH5440 printheads to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Our Miami location is ideal for Latin American UV and industrial print shops using freight forwarders in the Doral area.
