Aqueous & Textile DX4 Architecture Notice

The Mimaki JV22 / TX2 / JV4 Water-Based DX4 Printhead (part number M004372) is the authentic Japanese-manufactured OEM MicroPiezo replacement printhead engineered specifically for Mimaki's production-class water-based graphic, proofing, and textile engines (JV4-130/160/180, JV22-130/160, TX2-1600, DS-1600/1800, and GP-604/1810). Built with high-surface-energy aqueous fluidic chambers, this assembly is optimized for genuine water-based pigment, dye sublimation (Sb51/Sb52), reactive dye, acid dye, and disperse textile ink chemistries.

CRITICAL TECHNICAL & SERVICE ADVISORY

1. Water-Based vs. Solvent DX4 Differentiation (M004372 vs. M004905): The M004372 is engineered strictly for aqueous and textile inks (JV4, JV22, TX2). It is equipped with an aqueous manifold and adhesive seals. Do NOT introduce aggressive eco-solvent, mild-solvent, or UV-curable inks into this unit, as solvent carriers will rapidly dissolve internal adhesive bonding and cause permanent inter-channel cross-leakage. For solvent applications (JV3 Series), use M004905.

2. Mandatory Head-Rank ID Calibration: After mechanical installation, the technician MUST enter the alphanumeric Head-Rank ID (printed on the head label) into the printer via Service Mode (`[#] PARAMETER` > `HEAD ID`). Running without registered voltage rank parameters causes drop velocity deviations, satellite misting, or premature piezo fatigue.

3. Mandatory FFC Cable & Damper Servicing: Always install brand-new flat flexible head data cables (FFC) and new aqueous dampers concurrently. Reusing aged, creased, or ink-contaminated ribbon cables risks shorting the carriage slider PCB driver circuits, permanently damaging the main board.

4. Faceplate Maintenance Precautions: Never wipe the delicate nozzle face with dry shop wipes or abrasive cloths. Clean only using approved lint-free foam-tipped swabs moistened with genuine Mimaki aqueous cleaning solution. Inspect and service the capping station seals, wipers, and flush boxes regularly to avoid dried pigment build-up along the nozzle rows.

Condition: 100% Brand New, Genuine OEM Factory-Original Mimaki / Epson industrial replacement printhead assembly in sealed factory packaging with factory shipping preservation fluid intact.

Manufacturer Warranty: Covered under standard OEM parts limited warranty against material and manufacturing defects out-of-box prior to ink introduction. No warranty applies once active aqueous/textile ink or flush fluid has been introduced into the micro-fluidic chambers, or if damage results from head strikes, fabric jams, electrostatic discharge, or improper cable seating.

Return Policy: Precision industrial electronic component. Unopened, factory-sealed boxes with intact tamper-evident seals are eligible for standard commercial return. Once the vacuum seal is broken, protective nozzle tape removed, or the head mounted onto a carriage frame, returns cannot be accepted due to fluid priming, static risk, and electrical contamination hazards.
