The Mutoh DG-43988 is a genuine original Epson DX7-based printhead for the Mutoh Valuejet 1324, 1624, and related wide-format eco-solvent printer series. DG-43988 is the current consolidating part number, replacing the earlier DG-42271, DG-43345, DG-45279, DG-46892, and DG-42987. This assembly is supplied without the mounting bracket — the bracket from the previous head can be reused. Always replace head cables and DX6 Valve Dampers at the same time as the printhead. Every DG-43988 we sell at Digiprint USA is 100% genuine original Mutoh Japan.

If your service manual or previous invoice references any of those numbers, DG-43988 is the correct current replacement.

Contact our team if your bracket is damaged and needs replacement. What dampers does the DG-43988 require?The DG-43988 requires DX6 Valve Dampers.
