Mutoh DH-40865 Printhead

The Mutoh DH-40865 is an original UV printhead assembly for the Mutoh ValueJet 426 family, and many sellers list it as replacing the older DG-49990 part number. It’s typically sold as a full assembly that includes the printhead, dampers, and head cover, with compatibility most often listed for the 426UF, 626UF, 1626UH, 1638UH, 1638UR, 1638UR2, and 1638UH2 models.

Quick buyer view

If you need a fast purchasing decision, the main question is whether your printer model matches the listed compatibility and whether you want the full assembly version versus a head-only style replacement. One seller notes this part is the original Mutoh DH-40865 replacing DG-49990, while another source says DH-40866 is the related replacement part number for the same family.

Buyer checklist

•     Confirm your exact printer model before ordering, because compatibility is the biggest risk.
•     Verify whether your machine needs the full assembly with dampers and head cover, since that is how this part is commonly sold.
•     Check whether the seller is supplying an original Mutoh part or a compatible alternative, because listings differ.
•     Ask us about warranty, return policy, and installation support, since printheads are high-risk consumables.
