JV34 Compression Damper - M027904

The Mimaki JV34 Compression Damper (part reference M007846, current designation M027904) is a high-quality compatible solvent-resistant compression damper for the Mimaki JV34-260 wide-format eco-solvent printer and the Mimaki TS34-1800A dye-sublimation textile printer. Built for the Epson DX7 printhead used in both machines, this compression damper filters ink particles, buffers pressure fluctuations, and maintains stable ink delivery between the ink supply and the DX7 nozzle array. Each JV34 printhead requires 2 of these dampers for a complete service replacement. This is a high-quality compatible (non-OEM) replacement — genuine Mimaki OEM version also stocked separately.

M007846 and M027904 are the same damper — M027904 is the current active Mimaki part number. If your service documentation, printer manual, or prior order references M007846, M027904 is the correct current designation for the same assembly. This compatible listing is stocked under the M007846 reference specifically to serve buyers whose service records use the older number. No installation changes are required.

JV34-260 and TS34-1800A — Same Damper, Different Inks

The Mimaki JV34-260 is a high-production 102" eco-solvent wide-format printer; the TS34-1800A is a 71" dye-sublimation textile printer. Both use the Epson DX7 printhead and the same M007846/M027904 compression damper — the JV34/TS34 platform shares its ink delivery architecture across both ink systems. For mixed-fleet Mimaki operations running both eco-solvent and sublimation machines, this single part covers both platforms.

OEM vs Compatible — Which to Choose

This listing is the compatible/generic version of the JV34 compression damper. The genuine Mimaki OEM version (Japan origin) is stocked separately at a higher price. For mission-critical production environments, printhead warranty compliance, or where exact Mimaki pressure membrane specifications are required, the OEM version is recommended. For routine maintenance, cost-managed service operations, or mixed Mimaki fleet servicing, this compatible version provides the same physical dimensions and compression function at reduced cost.

Signs Your JV34 Dampers Need Replacing

• Banding on specific colour channels — pressure imbalance from a failing damper

• Air bubbles visible in the ink supply path

• Ink leaking at damper connections

• Nozzle drop-out returning rapidly after cleaning cycles

• Inconsistent ink density across long production print runs

JV34 Service Checklist

• Compression dampers (this listing) — 2 per head; replace both at every printhead installation

Frequently Asked Questions

Is M007846 the same as M027904?
Yes — both numbers refer to the same Mimaki JV34/TS34 compression damper assembly. M007846 is the earlier Mimaki designation still widely referenced in older service documentation and parts catalogues. M027904 is the current active Mimaki part number for the same assembly. If your records show M007846, ordering under either number gives you the same damper. We stock this listing under M007846 specifically to ensure buyers using older service documentation can find the correct part.

How many dampers does the JV34-260 require per head?
2 compression dampers per printhead. Replace both simultaneously — leaving one worn damper creates a pressure imbalance between the two channels causing the same banding and nozzle issues as a full damper failure.

Does M007846 fit the JV33 or JV150/JV300?
No. The JV34-260 uses M007846/M027904 (2 per head). The JV33/CJV30 uses M006579 SP — a different compression damper. The JV150/JV300/CJV150/CJV300 uses M022253 (4 per head). Confirm your specific Mimaki model before ordering.

Do you ship JV34 dampers to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Ideal for Latin American Mimaki JV34 and TS34 operators using freight forwarders in the Doral area.
