The DX4 Small Damper 2mm is a high-quality compatible solvent-resistant ink damper for Epson DX4-based eco-solvent and mild solvent wide-format printers from Roland, Mimaki, and Mutoh. Corresponding to Mimaki part references 1035836 and M004902, this small-size damper features a 2mm tube fitting, a large internal mesh filter for high-speed flow, and a precision O-ring on the outlet side to ensure a proper seal between the damper and the DX4 printhead. It is a compatible (non-OEM) generic replacement suitable for the Mimaki JV3, JV4, JV22, Mutoh Rockhopper, Rockhopper 3, Blizzard, Falcon, and Roland SP/VP/FJ DX4-based eco-solvent platforms.
Small damper (2mm) — confirm your printer's tube fitting size before ordering. Two damper sizes exist for the DX4 platform. This listing is the small damper with a 2mm fitting — correct for most Mimaki JV3/JV4/JV22 and Mutoh Rockhopper/Blizzard/Falcon printers that use 2mm ink tubes. A large damper with a 3mm fitting exists for Roland and other printers that require the larger connector. Check your printer's existing damper or service documentation to confirm which fitting size your machine uses before ordering.

Small vs Large DX4 Damper — Which Do You Need?
| Damper | Fitting | Connector OD | Primary Use |
|---|---|---|---|
| Small DX4 damper (this listing) | 2mm | OD 3.3mm | Mimaki JV3/JV4/JV22, Mutoh Rockhopper/Blizzard/Falcon |
| Large DX4 damper | 3mm | Larger connector | Roland SJ/FJ/XC/SP/VP DX4 printers, larger tube systems |
The safest way to confirm which damper your printer needs: remove an existing damper and measure the ink tube outer diameter at the fitting point, or check the damper's connector size against the spec above. If your Mimaki or Mutoh service manual references Mimaki part M004902 or 1035836, the small 2mm damper (this listing) is correct.

Why Large Mesh Matters for High-Speed DX4 Printing
The internal metallic mesh filter in a damper traps ink particles, pigment agglomerates, and micro-debris before they reach the DX4 printhead nozzles. A fine mesh provides better filtration but restricts flow — at the high print speeds of production eco-solvent printers, a fine-mesh damper can become a flow bottleneck, causing ink starvation that manifests as banding or nozzle row loss at speed. The large-mesh design in this damper deliberately sacrifices some particle filtration for substantially improved flow rate, matching the flow demand of high-speed DX4 print passes. This is particularly important for Mutoh Rockhopper and Mimaki JV series production printers running multi-pass jobs at maximum carriage speeds. The precision O-ring on the outlet side ensures the printhead-damper interface seals correctly regardless of the flow rate, preventing air ingestion at high speeds.
Signs Your DX4 Dampers Need Replacing
• Banding or nozzle row loss on specific colour channels — ink starvation from a clogged or restricted damper
• Air bubbles visible in the damper body — membrane failure allowing air ingestion
• Ink draining back out of the dampers and lines toward the cartridge — air leak through the damper
• Nozzle drop-out returning rapidly after cleaning cycles
• Discolouration or opacity change in the damper body — pigment accumulation on the mesh

Frequently Asked Questions
What is the difference between the small (2mm) and large (3mm) DX4 damper?
Both fit the Epson DX4 printhead but use different ink tube connectors. The small damper (this listing) has an OD 3.3mm connector for 2mm ink tube fittings — used in most Mimaki JV3/JV4/JV22 and Mutoh Rockhopper/Blizzard printers. The large damper has a larger connector for 3mm ink tube fittings — used in Roland SP/VP/SJ and some other DX4 platforms. Check your printer's ink tube diameter or your existing damper's connector size before ordering.
What Mimaki part numbers does this correspond to?
This generic DX4 small damper corresponds to Mimaki part numbers 1035836 and M004902. If your Mimaki service documentation references either of these numbers, this listing is the compatible replacement damper.
Why does this damper have a large mesh rather than a fine mesh?
Eco-solvent production printers running at high carriage speeds demand high ink flow rates through the damper. A fine-mesh damper provides better particle filtration but restricts flow, causing ink starvation banding at high speeds. The large-mesh design in this damper prioritises flow rate for high-speed production environments while still filtering macro-particles. For most production eco-solvent printing applications on Mimaki JV and Mutoh Rockhopper series printers, the large-mesh damper is the correct choice.
Do you ship DX4 small dampers to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Ideal for Latin American Mimaki JV3/JV4 operators, Mutoh Rockhopper service centres, and eco-solvent production facilities using freight forwarders in the Doral area.
