Factory-original Mimaki MP-M022625 (superseding / interchangeable with M015028) Gen5 (MH5420) industrial UV piezoelectric printhead engineered for Mimaki JFX200, JFX500, and UJV500 wide-format UV LED flatbed printers.
OEM Part Number: M022625 / MP-M022625 (Replaces M017004 & M015028) | Industrial Ricoh MH5420 Gen5 Drop-on-Demand (DoD) UV Printhead Assembly (incl. Heater)
The Original Mimaki Gen5 Printhead Assembly (M022625 / MP-M022625) is a heavy-duty industrial piezoelectric drop-on-demand (DoD) printhead engineered for continuous production on large-format 4 × 8 ft and 8 × 10 ft flatbed systems. Configured in 2-head or 3-head staggered carriage arrays on the JFX200-2513 and JFX200-2513 EX, this unit jets process colors (CMYK), high-density Opaque White, Gloss Clear, and Primer onto rigid substrates such as acrylic, wood, glass, aluminum composite panels, foam board, and metals up to 50 mm thick.
Engineered with 1,280 active addressable micro-nozzles configured across 4 separate rows (320 nozzles per row), the assembly supports 2-color and 4-color channel routing with a nozzle density of up to 600 NPI. Featuring multi-drop grayscale control with native drop sizes starting at 7 picoliters and variable drops up to 35 picoliters, the M022625 combines fine detail with solid color coverage. Its coated stainless steel (SST) nozzle plate and D33 stacked PZT piezo actuators offer rated mechanical durability of up to 100 billion actuations per nozzle.

1. Mandatory Firmware Verification (Recognition Lockout): The M022625 printhead uses an updated internal ID signature. Installing it in a printer running older firmware will result in a head recognition failure. You MUST update your machine firmware before installation:
• Mimaki JFX200-2513: Firmware version v2.60 or later required.
• Mimaki JFX200-2531: Firmware version v2.50 or later required.
2. Mandatory Head Cable (FFC) Replacement: Always install brand-new head data cables concurrently when replacing a Gen5 head. Reusing aged, bent, or ink-contaminated ribbon cables can short the slider PCB driver circuits, damaging the motherboard or the new printhead.
3. Head ID Input & Voltage Waveform Calibration: After mechanical mounting, enter the alphanumeric Head ID printed on the barcode label into the printer’s Service Mode menu (`[#] PARAMETER` > `HEAD ID`). Running a printhead without its specific voltage profile will cause droplet deflection, ink misting, or premature actuator failure.
4. Faceplate Maintenance Precautions: Never wipe the coated stainless steel nozzle plate with dry wipes or abrasive cloths. Clean only using approved lint-free foam-tipped swabs moistened with genuine Mimaki UV cleaning solution (F-200 / LF-200). Regularly inspect and clean the rubber capping station seals and wiper blades to prevent cured UV ink buildup.

Condition: 100% Brand New, Genuine OEM Factory-Original Mimaki Industrial Replacement Printhead in sealed factory packaging with factory 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 UV ink or flush fluid has been introduced into the micro-fluidic chambers, or if damage results from head strikes, substrate collisions, 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.
