The Mimaki JV34 Compression Damper (part number M027904, replacing earlier M007846) is a replacement 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 system and the DX7 nozzle array. Each JV34 printhead requires 2 of these dampers for a complete service replacement. This is a high-quality compatible replacement corresponding to Mimaki part reference M027904.
2 dampers required per JV34 printhead — replace both simultaneously. The Mimaki JV34-260 and TS34-1800A use 2 compression dampers per printhead. Replacing only one leaves a worn damper in the ink path, causing pressure imbalance between channels and ink starvation that produces the same banding and nozzle loss as before the service. Order 2 units for a single head replacement.

Compatible Printers
Mimaki JV34 Series (Eco-Solvent, 102" / 260cm)
• Mimaki JV34-260
Mimaki TS34 Series (Dye-Sublimation Textile)
• Mimaki TS34-1800A
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 M027904 compression damper — the JV34/TS34 platform shares its ink delivery architecture across both ink systems. For TS34-1800A operators, this means the same damper replacement part serves both eco-solvent and sublimation machines, simplifying spares management for mixed-fleet operations.
Mimaki DX7 Damper Family — JV34 vs JV33 vs JV150/JV300
Mimaki's DX7-based printers use different damper assemblies across generations. Do not substitute:
| Platform | Damper | Per Head |
|---|---|---|
| JV34-260 / TS34-1800A (this listing) | M027904 / M007846 | 2 |
| JV33 / CJV30 / TS3 | M007389 capping station (different assembly) | — |
| JV150 / JV300 / CJV150 / CJV300 | M022253 pressure damper assy | 4 |
Signs Your JV34 Dampers Need Replacing
• Banding on specific colour channels — pressure imbalance from a failing damper
• Air bubbles visible in the damper body — membrane failure allowing air ingestion
• Ink leaking at the damper connections
• Nozzle drop-out returning rapidly after cleaning cycles
• Inconsistent ink density across long print runs — progressive damper membrane fatigue

Frequently Asked Questions
Does M027904 replace M007846?
Yes — M027904 is the current Mimaki part number, superseding the earlier M007846. If your service documentation references M007846, M027904 is the correct current replacement. Both numbers refer to the same JV34/TS34 compression damper assembly.
How many dampers does the JV34-260 require per head?
2 compression dampers per printhead. Replace both simultaneously — leaving one worn damper in the ink path creates a pressure imbalance between the two channels that causes the same banding and nozzle issues as a full damper failure.
Can I use this damper for the JV33 or JV150/JV300?
No. The JV34-260 uses the M027904/M007846 compression damper (2 per head). The JV33/CJV30 uses a different compression damper assembly (M006579 SP). The JV150/JV300/CJV150/CJV300 uses the M022253 pressure damper assy (4 per head). These are not interchangeable. Always 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.
