Cjv300 Pressure Damper Assy - M022253

The Mimaki CJV300 Pressure Damper Assy (part number M022253, replacing earlier M015001) is the genuine original Mimaki replacement pressure damper assembly for the Epson DX7-based Mimaki CJV300, CJV150, JV300, JV150, JV100, TS100-1600, and TS55-1800 wide-format eco-solvent and dye-sublimation printers. This is a pressure-regulated damper assembly — Mimaki's term for a damper that actively maintains ink delivery pressure between the ink supply system and the DX7 printhead, preventing pressure spikes, air ingestion, and flow inconsistency. Every M022253 we stock at Digiprint USA is 100% genuine original Mimaki — not aftermarket, not compatible.

M022253 is the current Mimaki part — replacing discontinued M015001. If your service documentation, printer manual, or prior order references M015001, M022253 is the correct current replacement — no configuration changes required. Both numbers refer to the same pressure damper assembly for the CJV300/JV300/JV150/CJV150 platform.

JV150/JV300 vs JV33/CJV30 — Different Damper Families

Mimaki's DX7-based printer families use different damper assemblies. Do not confuse:

Platform	Damper Part	Models
JV150 / JV300 / CJV150 / CJV300 (this listing)	M022253	Newer DX7 generation — eco-solvent and sublimation
JV33 / CJV30 / TS3	M007389 (capping station) — different damper assembly	Older DX7 generation

What Does a Pressure Damper Assy Do?

The Mimaki "Pressure Damper Assy" is the term for the pressure-regulated ink delivery assembly that sits between the CJV300/JV300's ink supply and the DX7 printhead manifold. It performs three functions: it absorbs pressure spikes caused by the carriage's rapid acceleration and deceleration, smoothing out pulsation that would otherwise cause inconsistent drop ejection at high print speeds; it filters ink particles through an internal mesh before they reach the DX7 nozzles; and it maintains a calibrated back-pressure at the nozzle face, preventing ink from freely dripping from the nozzle openings during carriage movement and idle periods. When the damper assembly fails — through membrane fatigue, filter blockage, or seal degradation — any combination of banding, nozzle loss, and ink starvation on specific channels follows. Because each ink channel has its own pressure damper, channel-specific symptoms are the typical sign of a damper failure rather than a printhead failure.

Sublimation Models (TS100-1600 / TS55-1800) — Same Damper

The Mimaki TS100-1600 and TS55-1800 are dye-sublimation textile printers that use the same DX7 printhead and M022253 pressure damper assembly as the eco-solvent JV/CJV series — the same platform architecture deployed across different ink systems. If you are servicing a TS100-1600 or TS55-1800, M022253 is the correct damper regardless of the dye-sublimation ink chemistry. This cross-series compatibility simplifies spares management for Mimaki operations running both eco-solvent and sublimation machines.

Signs Your M022253 Dampers Need Replacing

• Banding or nozzle loss on specific colour channels — pressure damper failure causing ink starvation on those channels

• Air bubbles visible in the damper body — membrane failure or seal breach allowing air ingestion

• Ink leaking from the damper body or connections — seal failure

• Nozzle drop-out that returns rapidly after cleaning — continuous air drawn through a compromised damper

• Pressure irregularities manifesting as tonal inconsistency across a long print run

Frequently Asked Questions

Does M022253 replace M015001?
Yes. M015001 is the earlier Mimaki part number for this pressure damper assembly — it has been discontinued and replaced by M022253. If your service documentation, printer manual, or prior order references M015001, M022253 is the correct current replacement. No configuration changes are required — the M022253 is a direct drop-in.

Is this the same damper as the JV33/CJV30?
No. The JV33/CJV30 generation uses a different damper assembly. The M022253 is for the newer JV150/JV300/CJV150/CJV300 generation. Do not substitute M022253 for the JV33/CJV30 damper or vice versa — confirm your specific Mimaki model generation before ordering.

Does M022253 fit the TS100-1600 dye-sublimation printer?
Yes. The Mimaki TS100-1600 and TS55-1800 are dye-sublimation textile printers built on the same platform as the JV/CJV eco-solvent series, using the same DX7 printhead and M022253 pressure damper. The M022253 is compatible with both eco-solvent and sublimation applications on these printers.

Do you ship Mimaki CJV300 dampers to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Ideal for Latin American Mimaki CJV300/JV300 operators, eco-solvent sign shops, and sublimation production facilities using freight forwarders in the Doral area.
