OEM Wide-Format Eco-Solvent / Dye-Sublimation Component
Original Mimaki 5540 Printhead Assembly with Memory Board (M015372)
OEM Part Number: M015372 / MP-M015372 (Replaces M015307) | Complete Micro-Piezo DX7-Class Printhead Assembly with Pre-Mounted Head Memory Board
High-Speed DX7 Architecture & Memory Board Integration Notice
The Mimaki M015372 5540 Head Assy (officially superseding factory part number M015307) is the genuine OEM micro-piezoelectric drop-on-demand replacement assembly engineered for Mimaki’s high-speed wide-format roll-to-roll platforms (including the JV300, CJV300, JV150, CJV150 series, as well as the TxF Direct-to-Film (DTF) series). Unlike bare core modules, this assembly includes the factory pre-mounted, encrypted Head Memory Board PCB and long-reach ribbon data harness (354 mm length × 30 mm width) matched directly to Mimaki slider board architectures.
Product Overview
The Original Mimaki 5540 Printhead Assembly with Memory Board (M015372) is a factory-original multi-channel piezoelectric drop-on-demand printhead unit engineered for high-throughput commercial sign production, vehicle wraps, backlit displays, fine-art graphics, and DTF film manufacturing. Operating in a single-head (JV150/CJV150) or dual-staggered carriage array (JV300/CJV300), this assembly delivers print speeds up to 105.9 m²/h while maintaining precise dot placement and circularity.
Configured with 1,440 active addressable micro-nozzles partitioned across 8 independent channels (180 nozzles per row), the unit achieves native output resolutions up to 1440 DPI. Leveraging advanced 3-way Variable Sized Droplet Technology (VSDT), the 5540 head fires droplet sizes ranging from an ultra-fine 1.5 picoliters for smooth photographic gradients up to heavy droplets for dense solid coverage. The integrated factory memory board interfaces directly with the printer's firmware to authenticate the assembly and synchronize voltage driving pulses, protecting the head from wave-deflection, misting, and electrical overload.

Key Features & Operational Advantages
- Integrated Encrypted Memory Board: Ships with the factory-matched green memory PCB and long-reach cable pre-installed, eliminating firmware handshake errors and avoiding the risks of board swapping.
- 3-Way Variable Sized Droplet Technology (VSDT): Precisely ejects 1.5 pl micro-droplets for skin tones and smooth vignettes while producing larger drops for dense, vibrant solid color blocks without banding.
- Eco-Solvent & Sublimation Passivation: Factory-bonded using solvent-resistant epoxy adhesives that resist swelling and delamination when running aggressive eco-solvent (SS21) or dispersed sublimation inks.
- Seamless MAPS4 & NRS Integration: Works directly with Mimaki Advanced Pass System 4 (MAPS4), Nozzle Check Unit (NCU), and Nozzle Recovery System (NRS) for continuous unattended manufacturing runs.
CRITICAL TECHNICAL & SERVICE ADVISORY
1. Platform Incompatibility with Older DX5 Models: The M015372 5540 assembly is engineered specifically for Mimaki’s DX7-based carriage systems (JV150, CJV150, JV300, CJV300). It is physically, electrically, and fluidically incompatible with legacy DX5 platforms (such as JV33, CJV30, or JV5, which use M007947 / F160010). Never attempt to install this unit into a DX5 carriage.
2. Pre-Mounted Memory Board Notice: Because this assembly includes the genuine factory Memory Board with its pre-flashed encryption key, technicians do NOT need to unclip and transfer the fragile circuit board from the failed head. Ensure the 354 mm ribbon cables are routed cleanly through the carriage shield channels without pinching or sharp twisting.
3. Mandatory Head ID Input: After physical installation, the technician MUST enter the alphanumeric Head ID value (printed on the barcode label) into the printer’s Service Mode menu (`[#] PARAMETER` > `HEAD ID`). Operating the printhead with improper voltage rank profiles will result in droplet deflection, misting, or premature piezo fatigue.
4. Valve Damper & Cap Top Servicing: Always replace the DX6/DX7-style valve dampers (M015001 / M028290) concurrently with the printhead. Inspect the rubber capping station seals and wiper blades before charging ink; operating with a worn cap top or dry wiper blade will degrade the nozzle plate surface and cause chronic dropouts.
