OEM Industrial Precision UV Flatbed Component
Original Mimaki UJF-605CII Head Assy CA4 (M007040)
OEM Part Number: M007040 / MP-M007040 (Replaces M005574 & CA4-A01 Core Code) | Industrial Toshiba TEC CA4 Multi-Drop Grayscale Piezoelectric UV Printhead Assembly (incl. Integrated Heater & Thermistor)
High-Accuracy Industrial Flatbed CA4 Architecture Notice
The Mimaki M007040 Head Assy CA4 (superseding factory part number M005574) is an authentic OEM industrial drop-on-demand replacement assembly engineered specifically for Mimaki’s high-precision UJF-605C and UJF-605CII UV-LED flatbed production engines. Built around the proven Toshiba TEC CA4 shared-wall piezoelectric platform, this complete assembly integrates a factory-calibrated internal heating block, high-precision thermistor sensor harness, and specialized solvent/UV-resistant internal manifold passivations configured for genuine Mimaki LH-100 and SPC-0371 UV-curable inks.
Product Overview
The Original Mimaki UJF-605CII Head Assy CA4 (M007040) is an authentic factory electro-mechanical printhead unit engineered for ultra-fine micro-text, optical instrumentation marking, membrane switches, architectural dials, industrial nameplates, and rigid packaging prototypes. Operating in a multi-head precision carriage array within the UJF-605C / UJF-605CII platforms, this module powers process colors (CMYK), Light Cyan, Light Magenta, high-density White underbase/overbase, and Clear finish over flat rigid media up to 50 mm in thickness.
Engineered with 318 active addressable micro-nozzles configured in a high-precision linear orifice array across a 53.6 mm active swathe, the CA4 platform achieves native optical resolutions up to 1200 × 1200 DPI. Leveraging advanced multi-drop grayscale waveform modulation, the unit dynamically ejects droplet sizes from 6 picoliters up to 42 picoliters across up to 8 distinct grayscale levels. This dynamic volume control produces smooth photographic skin tones and razor-sharp 2-point vector characters, while enabling dense, solid flood-coating in fewer carriage passes. The internal thermal management block warms heavy UV monomers directly behind the nozzle acoustic cavity, ensuring consistent drop ejection velocity regardless of workshop ambient swings.

Key Features & Operational Advantages
- Toshiba CA4 Actuator Reliability: Industrial shared-wall 3-cycle piezo engine delivers uniform firing energy across all 318 channels, offering high mechanical durability under continuous industrial operating schedules.
- 8-Level Multi-Drop Grayscale: Dynamically modulates drops between 6 pl and 42 pl, enabling crisp 2-point micro-text on membrane switches alongside heavy solid builds on acrylics and metals.
- Integrated Fluid Heating & Feedback: Built-in heater block warms high-viscosity LH-100 UV inks directly at the acoustic chamber, stabilizing fluid meniscus pressure and preventing drop deflection caused by ambient room fluctuations.
- Direct Drop-In OEM Compatibility: Serves as the factory direct replacement for superseded part number M005574, fully restoring print swathe parallelism, drop velocity, and platen height calibration.
CRITICAL TECHNICAL & SERVICE ADVISORY
1. CA4 vs. CA3 & CE4 Architecture Differentiation: The M007040 is engineered around the Toshiba TEC CA4 core specifically for UJF-605C and UJF-605CII platforms. Although sharing structural similarities with the CA3 head (M007278 for JF-1610) and the CE4 head (M018821 for UJF-3042 MkII), internal drive waveforms, thermistor impedance profiles, and firing response frequencies differ. Never cross-install across platform classes without verifying head driver board compatibility.
2. Precision Alignment Plate Transfer: The OEM service package M007040 includes the calibrated head body with integrated heater and thermistor harness, but does not include the cast aluminum carriage alignment base plate. Technicians must clean and transfer the existing mounting bracket from the failed head, taking care to inspect indexing guide pins for mechanical wear or cured UV ink residue.
3. Mandatory Head ID Voltage Registration: After physical mounting and ribbon cable attachment, 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 the printhead without registering its factory-assigned voltage rank will cause droplet deflection, ink misting, or premature actuator failure.
4. Faceplate Maintenance Precautions: Never wipe the delicate orifice 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). Inspect and clean the rubber capping station seals and wiper blades regularly to avoid cured UV ink accumulation around the nozzle row.
