Compatible printers and connector size

This pack contains ten replacement ink dampers sized for a 4×3 mm big connector and a 3×2 mm small connector. They are designed for DX4 and DX5 print heads used in Roland PS, SP, RS, VS, XJ, VP and XC models including the 300, 420, 540, 640 and 740 series. Formimaki JV3, JV4 and JV22 printers are also supported.

Installation notes and common issues

Each damper filters ink before it reaches the print head and is fitted by pushing the connector onto the corresponding ink line. Misalignment of the 4×3 mm or 3×2 mm ports can cause leaks, and reusing old O-rings often leads to air bubbles that interrupt flow. Clean the mounting area thoroughly before fitting new units.

Check your current setup before ordering

Verify that your printer uses DX4 or DX5 heads and that the ink lines terminate in the 4×3 mm big and 3×2 mm small connectors listed. Confirm the exact model number matches the Roland or Formimaki series shown, as other models may use different connector dimensions.

Questions about this item

How can I verify the 4x3mm big connector damper is filtering ink correctly after installing it on my Roland XC540?

After fitting the 4x3mm big connector damper on the Roland XC540, run a nozzle check and confirm smooth ink flow with no air bubbles visible in the damper body.

What comes in the 10-piece pack and what must I source separately for a Roland VS 640 installation?

The pack contains ten DX4/DX5 big ink dampers with 4x3mm connectors; tubing, clamps and ink are not included and must be purchased separately.

Which damper version matches the 3x2mm small connector used on a Mimaki JV22 printer?

These dampers have a 4x3mm big connector and a 3x2mm small connector; choose this version when the printer requires the 3x2mm small connector size.
