MF-5040 – Printhead fuse 1260FA 750 mA (Head Fuse) – Mutoh ValueJet VJ-1204 / VJ-1604 / RJ-900C

The MF-5040 printhead fuse (Head Fuse 1260FA, 750 mA) is the electrical protection of the printhead on the Mutoh ValueJet large-format printers.

Fitted on the mainboard, this quick-blow fuse (type 1260FA — 750 mA) instantly cuts the circuit on an overvoltage or short circuit, preventing irreversible damage to the printhead. It is the first component to check on a sudden head failure or a jet loss after an electrical incident.
