High-Throughput Industrial UV Production Architecture Notice
The Mimaki M022626 / MP-M022626 Gen5 Printhead Assembly is an authentic OEM industrial drop-on-demand replacement module engineered specifically for Mimaki’s high-throughput grand-format flatbed and super-wide roll-to-roll UV-LED production platforms (primarily the JFX500-2131, UJV500-160, UJV55-320, and SIJ-320UV). Based on the industrial Ricoh Gen5 (MH5420 core) architecture, this assembly features a dedicated multi-channel UV fluid manifold, high-precision thermal feedback, and chemically passivated cavity seals designed for continuous jetting of Mimaki LUS-120, LUS-150, LUS-200, and LH-100 UV inks across 6-head and staggered carriage arrays.
Product Overview
The Original Mimaki Gen5 Printhead Assembly M022626 (MP-M022626) is a heavy-duty electro-mechanical printhead unit designed for continuous commercial manufacturing across rigid display substrates, acrylic panels, architectural glass, foam board, fluted polypropylene, backlit films, and super-wide flexible banners up to 3.2 meters wide. Configured in a high-speed multi-head staggered carriage setup (featuring 6 printheads in the JFX500-2131 to achieve print speeds up to 60 m²/h), this assembly fires process colors (CMYK), Light Cyan, Light Magenta, and high-opacity White with micron-level landing accuracy.
Engineered with 1,280 active addressable micro-nozzles partitioned across 4 independent rows (320 nozzles per row), the unit achieves native optical output resolutions up to 1200 DPI. Leveraging advanced multi-drop grayscale waveform pulse shaping, it ejects native 7 picoliter micro-drops up to 35 picoliters, producing smooth photographic gradients, razor-sharp 2-point vector text, and dense, pinhole-free solid fills. Its solid stainless-steel chassis, isolated D33 PZT piezo actuators, and fluororesin-passivated faceplate deliver high mechanical durability rated up to 100 billion actuations per nozzle.
CRITICAL TECHNICAL & SERVICE ADVISORY
1. Platform Differentiation Across Mimaki Gen5 Lineup: While the M022626 shares the core Ricoh Gen5 MH5420 physical geometry with other Mimaki Gen5 variants, it is specifically configured for JFX500-2131, UJV500-160, UJV55-320, and SIJ-320UV platforms. It differs from:
• M022625 (JFX200 Series): Configured with distinct mounting bracket hardware and electrical sub-harness routing.
• M026887 (UCJV300 Series): Features different sub-tank joint interface brackets and resistance curves.
• M022650 (SWJ-320 Series): Engineered strictly for solvent inks; lacks UV internal passivation.
• M022651 (JV400-LX Series): Engineered strictly for aqueous latex resin dispersions.
Never cross-install Gen5 variants without verifying the machine parts manual and PCB interface level.
2. Staggered Carriage Slant & Registration Calibration: On the JFX500 6-head array, installing a replacement head requires mechanical slant alignment followed by service mode electronic registration (`[#] ADJUST` > `HEAD SP-ADJUST` and `SLANT ADJUST`) to align all 6 heads across both scanning directions.
3. Mandatory Head ID Voltage Registration: After physical mounting and cable connection, the technician MUST enter the alphanumeric Head ID value (printed on the barcode label) into the printer’s Service Mode menu (`[#] PARAMETER` > `HEAD ID`). Running a Gen5 head without its specific factory-calibrated voltage table will cause drop deflection, ink misting, or premature piezo fatigue.
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 UV cleaning solution (F-200 / LF-200). Inspect and clean the rubber capping station seals and wiper blades regularly to prevent cured UV ink accumulation around the nozzle row.
Terms, Warranty & Customer Protection
Condition: 100% Brand New, Genuine OEM Factory-Original Mimaki / Ricoh 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 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.
