The Mimaki MP-M015372 (Alternative Part Number: M015372 / Replaces: M015307) is a 100% genuine, factory-original CJV300 5540 Printhead Assembly (DX7 Micro-Piezo Head) manufactured by Mimaki in Japan. Complete with integrated head data cables and the native memory board, this component serves as the core imaging matrix for Mimaki’s flagship eco-solvent, mild-solvent, and sublimation inkjet printers. Replacing a blocked or electrically degraded head with this authentic OEM part fully restores the machine's out-of-the-box 1440 dpi text sharpness, flawless color gradients, and heavy-duty high-speed production capability.
Key Functions
Advanced Micro-Piezo Jetting: Employs state-of-the-art piezo crystallization grids that vibrate under precise voltage signals to fire ink droplets rapidly through 1,440 precise nozzles (arranged in 8 lines × 180 nozzles).
Variable Droplet Technology: Dynamically modulates ink delivery to fire droplets ranging from a microscopic 1.5 picoliters up to 21 picoliters in a single pass, creating exceptionally smooth skin tones and intense solid fills.
Integrated Memory Sync: The onboard memory chip communicates directly with the printer's motherboard to instantly sync native voltage calibration files, eliminating manual configuration delays.
Core Advantages
100% Genuine OEM Quality: Certified Japanese-made Mimaki hardware. It matches your exact system firmware waveforms, eliminating the common pass-alignment errors and short-circuit risks associated with unlocked generic heads.
Robust Chemical Fortification: Engineered with specialized internal head coatings and industrial-grade manifolds optimized to resist aggressive eco-solvent chemicals and high-saturation dye-sublimation ink matrices.
High-Frequency Firing Frequency: Operates comfortably at an 8 kHz firing threshold, enabling continuous wide-span printing without dropping print resolution or inducing physical data trail errors.
Direct Factory Upgrade: Fully replaces legacy part iteration M015307 with updated physical cable shielding (354mm length × 30mm width) to better ward off environmental static discharge.
