Mimaki 5540 Head Assembly
Genuine Mimaki 5540 replacement printhead assembly with cables and memory board, engineered for compatible Mimaki wide-format printers to restore precise ink delivery, nozzle performance, and dependable print quality.
Characteristics
The Mimaki 5540 Head Assembly – M015372 is a genuine replacement printhead assembly designed for compatible Mimaki wide-format inkjet printers.
This complete head assembly is supplied under Mimaki part number M015372 and replaces the previous M015307 head assembly. It includes the printhead, connection cables, and head memory board required for compatible installations.
The 5540 Head Assembly uses Micro-Piezo printhead technology to provide precise control of ink droplets during printing. With a native resolution of 1440 dpi, the head is designed to support detailed graphics, smooth tonal reproduction, sharp text, and consistent production output.
The printhead incorporates a total of 1,440 nozzles arranged in 8 lines of 180 nozzles. This nozzle configuration provides controlled ink placement across the printing area while supporting the productivity and image quality required in professional wide-format printing environments.
A minimum droplet size of approximately 1.5 picoliters allows the head to produce very fine ink droplets for detailed image reproduction and smooth gradations. The head has a specified firing frequency of 8 kHz.
The M015372 assembly is designed for use with compatible eco-solvent and mild-solvent ink systems and is suitable for supported Mimaki printer and printer/cutter configurations.
Compatible printer families include the Mimaki CJV300, JV300, CJV150, and JV150 Series. Because printhead compatibility can vary by printer configuration and production generation, the printer model and existing head part number should always be verified before ordering.
As one of the printer's primary imaging components, the printhead is responsible for accurately jetting ink onto the media. A worn, damaged, or malfunctioning printhead can contribute to missing nozzles, banding, inconsistent color, poor image quality, or other printing problems.
Replacing a failed printhead with the correct genuine Mimaki assembly helps restore the printer's intended ink-jetting performance while maintaining compatibility with the printer's electronics and ink delivery system.
Professional installation is recommended. Printhead replacement may require service-mode procedures, mechanical alignment, electronic configuration, and print adjustments after installation.
