Compatible DX7 DX6 Printhead Dampers

This pack contains ten UV ink dampers built for DX7 and DX6 printheads. They fit Roland RA-640, RE-640, VS-640 and VS-540 printers as well as Mutoh Valuejet 1608, 1618, 1624E and 1638 models. The parts are supplied new and ready for direct replacement. They address the need for consistent ink flow in high-volume UV printing environments.

Ink Flow Stability and Maintenance

Each damper regulates ink pressure to reduce starvation and air bubbles during long print runs. Stable delivery lowers the risk of nozzle drop-out and wasted media. The components are passive, so they add no electrical load or audible noise to the system. Regular replacement keeps print quality predictable without extra power draw.

Questions about this item

How is the DX7 DX6 damper installed on a Roland VS-640 and which step is often missed?

Remove the old damper, press the new unit onto the printhead nozzle until it clicks, then prime the ink lines; the step often missed is priming, which prevents air bubbles in UV ink.

What maintenance will the 10 UV ink dampers need during their service life?

Inspect the mesh filter weekly for pigment buildup, flush with compatible UV cleaning fluid during colour changes, and replace any damper that shows reduced ink flow or leakage.
