Ricoh MH5420 vs MH5440 — Complete Comparison Guide
Ricoh MH5420 vs MH5440: What's the Difference?
The Ricoh MH5420 and MH5440 are frequently confused because they're built on the exact same physical platform — same 1,280 nozzles, same 600 dpi resolution, same 7pl drop size, same dimensions. The only difference is how many ink colours each head can carry at once.
The short answer: the MH5420 is the 2-colour version (2 × dual ink ports). The MH5440 is the 4-colour version (4 × dual ink ports). If your printer needs full CMYK from a single head, you need the MH5440. If your printer runs 2 colours per head — often in a multi-head carriage design — you need the MH5420.
They are physically interchangeable in terms of mounting and electrical connection, but not functionally interchangeable — installing a 2-colour MH5420 in a system wired for 4 ink channels will only give you 2 working colour channels, and vice versa can damage or waste ink paths. Always confirm which model your printer's service documentation specifies before ordering.

Which One Do I Need?
Choose the MH5420 (2-colour) if:
- Your printer's carriage uses multiple heads, with each head assigned to 1–2 colours
- Your printer's service documentation or currently-installed head is stamped with a Ricoh code beginning N221414 (J/L/E) or J3600x
- You're replacing a head in a system with 6+ printheads (common in high-colour-count industrial UV flatbeds)
Choose the MH5440 (4-colour) if:
- Your printer is designed around a compact head count, with each head carrying full CMYK
- Your printer's documentation specifies "MH5440" directly, or a part number distinct from the MH5420 codes above
- You're working with a system that uses fewer, higher-capability heads rather than many single/dual-colour heads
Not sure which your printer uses? Check the part number printed on your currently installed head, or your printer's service manual. Contact our team with your printer make and model — we'll confirm the correct model before you order, at no charge.
Why the Confusion Happens
Ricoh markets these two heads together as a single product family ("MH5420/5440") on their own site, because they share a datasheet and are built on the same platform — Ricoh's documentation covers both models side by side rather than as fully separate products. That's efficient for Ricoh's engineering documentation, but it means buyers researching "Ricoh MH5420" often land on specs that actually describe the 4-colour MH5440, or vice versa, without realizing the port count differs between the two. When ordering, always go by ink port count and part number — not just the "MH54" family name.
Cable Length and Ink Type Variants
Both the MH5420 and MH5440 are available in different cable lengths and, for the MH5420, different ink-type configurations:
- MH5420 (UV/solvent): available in 248mm (N221414J), 500mm (N221414L), and 650mm (N221414E) total assembly lengths — all 2-colour.
- MH5420 (water-based): available in 248mm (J36002) and 650mm (J36004/N221414D) — also 2-colour, for aqueous ink systems like Hollanders, ATP Color, and MTEX platforms.
- MH5440: standard 248mm total length, 4-colour, UV/solvent/aqueous compatible.
Cable length is determined by your printer's internal carriage-to-electronics routing distance — not by print specification. Confirm the correct length from your printer's service documentation or the part number on your currently installed head.
Frequently Asked Questions
Are the MH5420 and MH5440 interchangeable?
Physically, they mount and connect the same way. Functionally, no — the MH5420 only has 2 ink paths wired in, while the MH5440 has 4. Installing the wrong one means either losing colour channels (MH5420 in a 4-colour system) or an incompatible ink routing setup (MH5440 in a 2-colour system). Always match to your printer's specified model.
Does the MH5440 cost more than the MH5420?
Generally yes, since it has double the ink ports and is designed for systems that consolidate more colour capability into fewer heads. Exact pricing depends on cable length and ink-type variant — see our current listings for both models.
Can I upgrade from MH5420 to MH5440 for more colours?
Only if your printer's carriage and ink delivery system is designed to route 4 independent ink channels to a single head. Most printers built around the 2-colour MH5420 don't have this wiring, so this isn't typically a drop-in upgrade — check with your printer manufacturer or contact our team to confirm.
Do MH5420 and MH5440 use the same ink?
Yes — both are compatible with UV-curable, solvent, and aqueous inks within the same viscosity and surface tension ranges. Ink compatibility isn't the differentiator between the two models; ink port/colour count is.
Do you ship Ricoh MH5420 and MH5440 printheads to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse on orders placed before 2PM EST. Our Miami location is ideal for Latin American UV flatbed and industrial print shops using freight forwarders in the Doral area.
