Mutoh DG-49580 Printhead

The Mutoh DG-49580 (also sold as DH-40274 / Mutoh I9472 MS41) is an OEM Piezo printhead used in Mutoh XpertJet wide-format printers; it has 180 nozzles × 8 lines, droplet size 3.5–35 pl, multiple selectable resolutions, and three head-height settings — making it suited for high-speed eco‑solvent signage work; alternatives and pricing vary by seller and some newer Mutoh heads (DH-40275 and other DH-series) are listed as replacements or related SKUs for different printers.

Buying considerations

•     OEM vs third‑party: This part is sold as an OEM Mutoh head (DG‑49580 / DH‑40274); OEM inventory and prices fluctuate and some list replacements under different DH part numbers, so verify the exact PN for your printer before purchase.
•     Cost range and availability: Prices depending on model and whether it’s sold as an assembly or head-only; confirm whether the base, cable, or mounting plate is included in the listing.
•     Compatibility check: Match your printer model (exact XpertJet model and firmware) to the head PN - note DH-40275 replaces DG‑49580 for particular printers, so cross-reference with Mutoh or us.
•     Life and maintenance: Expect long service life from OEM Piezo heads with proper maintenance, but plan for periodic replacement and have cleaning/maintenance routines in place to protect nozzle health.

Alternatives and comparison (quick)

•     Direct Mutoh replacements: DH-series OEM heads (DH‑40274 / DH‑40275) are the direct Mutoh options or updated replacement SKUs for certain machines.
•     Other printhead families to consider (if switching platforms): Epson DX5/DX7-based heads and Konica/Toshi/Seiko heads are common in other wide-format machines; choosing these often requires a different printer platform rather than a direct swap.
•     When to choose DG‑49580: If you run a Mutoh XpertJet 1641SR (or listed compatible XpertJet models) and need OEM reliability, the DG‑49580/DH‑40274 is the appropriate choice.

Short purchase checklist

•     Confirm exact printer model and firmware match for DG‑49580/DH‑40274 compatibility.
•     Verify whether the listing includes only the head or the head assembly with base/cable/mounting hardware.
•     Ask us about return policy, warranty, and a tested/nozzle-included guarantee (sometimes we test heads before shipping).
