Factory-original Mimaki M017429 (superseding / interchangeable with MP-M025074) industrial on-demand piezo printhead engineered specifically for the Mimaki UJF-7151 Plus and UJF-7151 Plus II UV flatbed printers.
OEM Industrial UV-LED Component
Original Mimaki UJF-7151 Plus Printhead (M017429 / MP-M025074)
OEM Part Number: M017429 / MP-M025074 (Core Code: Toshiba TEC CF1 / CA4 Architecture) | High-Precision Industrial Piezoelectric DoD UV-Curable Printhead
Industrial UV Flatbed & Active Recirculation Architecture Notice
The Mimaki M017429 Printhead (and factory service replacement code MP-M025074) is an authentic OEM industrial piezoelectric drop-on-demand replacement module engineered specifically for Mimaki’s flagship high-accuracy UV flatbed printers (including the UJF-7151 Plus and UJF-7151 Plus II). Built upon an industrial shear-mode PZT actuator platform with active ink recirculation and an internal fluid-heating manifold, this head delivers high dot landing precision for fine art, industrial nameplates, dials, and heavy promotional substrates.
Product Overview
The Original Mimaki UJF-7151 Plus Printhead (M017429 / MP-M025074) is a heavy-duty industrial printhead engineered to meet demanding industrial manufacturing standards, high-throughput commercial customization, and precision instrument marking. Arranged in a 6-head staggered carriage configuration on the UJF-7151 Plus platform, this unit drives process colors (CMYK), high-density Opaque White, Gloss Clear, and Primer onto rigid plastics, glass, metals, acrylics, wood, and leather up to 153 mm thick.
Engineered with 636 active addressable micro-nozzles configured in high-density linear arrays, the printhead achieves native optical output resolutions up to 1200 × 1200 DPI. The unit integrates an active internal ink circulation channel that continuously cycles UV-curable ink directly past the nozzle chambers. This constant movement prevents pigment settling—critical for titanium dioxide white ink and metallic formulations—while automatically purging micro-bubbles and preventing nozzle dropouts during long industrial production cycles.

Key Features & Operational Advantages
- Active In-Head Recirculation: Continuous ink flow immediately behind the nozzle plate prevents titanium dioxide pigment sedimentation, minimizes air bubble accumulation, and reduces automated purge cycles.
- Industrial Jetting Accuracy: Shear-mode PZT actuators fire droplets along straight flight paths, ensuring sharp edge registration, legible 2-point micro-text, and precise barcode lines on thick substrates.
- Built-In Viscosity Conditioning: Onboard heating elements warm high-viscosity UV-curable inks to optimal firing temperature, ensuring reliable droplet ejection across varying workshop environments.
- Universal Single-SKU Architecture: One part number fits any color, white, clear, or primer station across the 6-head carriage array, simplifying shop spare parts management.
CRITICAL TECHNICAL & SERVICE ADVISORY
1. Platform Incompatibility with Desktop UJF Series: The M017429 / MP-M025074 is engineered specifically for the Mimaki UJF-7151 Plus series. It cannot be used in compact entry-level flatbed models (such as UJF-3042FX/HG, UJF-6042, or UJF-3042MkII / UJF-6042MkII, which use Epson or Ricoh-based heads like M010010 or M005860). Physical mountings, recirculation connections, and electrical pinouts are completely different.
2. Mandatory Head ID Parameter Registration: Following mechanical docking, the technician MUST enter the alphanumeric Head ID value (printed on the barcode label) into the printer's service maintenance parameters (`#PARAMETER` > `HEAD ID`). Operating without registration will lead to incorrect drive voltages, droplet deflection, and premature actuator damage.
3. Circulation Loop Priming & De-aeration Protocol: Always prime the supply and return fluid loops using the printer's service maintenance routine until the lines are entirely free of micro-bubbles. Trapped air inside the internal heating chamber will disrupt meniscus pressure, causing temperature errors and severe nozzle dropouts.
4. Faceplate Maintenance & Capping Care: Never wipe the nozzle plate with dry shop wipes or abrasive materials. Use only genuine lint-free swabs moistened with approved Mimaki UV cleaning liquid (such as F-200 / LF-200 wash). Inspect rubber cap tops and wiper blades regularly to avoid cured UV ink accumulation along the nozzle plate perimeter.
