50-Pack DX4 DX5 Printhead Dampers

This pack contains fifty small ink dampers built for DX4 and DX5 printheads. They fit Roland SP540, Mutoh RJ900, Mimaki JV3 and Epson R1800, R1900 and 1390 wide-format printers. The parts are new and function as direct replacements for worn or clogged originals.

PE Body With Large-Area Filter

Each damper uses a PE housing and an imported large-area filter structure. The design handles water-based, eco-solvent, dye, pigment and thermal-transfer inks without plugging. The filter surface improves fluidity, resists corrosion and helps extend nozzle life in compatible-ink environments.

Confirm Printhead And Connector Size

Verify that your machine uses DX4 or DX5 heads and accepts the 3*2 small connector before ordering. The dampers are not suited for printers that require a different damper body or connector layout. Buyers needing a different connector pitch or a larger damper body should look for the matching part number.

Questions about this item

How often should the DX4 DX5 small ink dampers be replaced to maintain print quality?

Replace dampers when ink flow becomes inconsistent or filters show clogging; the 50-piece pack supports multiple service intervals for Roland SP540, Mutoh RJ900, and Mimaki JV3 printers.

What limits continuous printing before a damper change is needed?

The imported large-area filter handles ECO-solvent, dye, pigment, and thermal-transfer inks; saturation or particle buildup is the first limit under sustained use.

Do the dampers add heat or noise during all-day operation?

Passive PE components with 3×2 small connectors add no heat, noise, or power draw; they simply filter ink for compatible water-based or solvent machines.
