Galaxy PH 256/80HM Printhead

    Galaxy PH 256/80HM is a 256-channel hot-melt inkjet printhead designed for high-performance industrial and commercial applications, delivering up to 400 dpi in some configurations (commonly cited up to 400–450 dpi depending on fluid and firmware) with 80 picoliter drop size. It ships as a complete head assembly including jetting components, on-head fluid reservoir, and drive electronics, suitable for hot-m melt jetting fluids. This makes it well-suited for packaging, wide-format graphics, and other high-volume production contexts where robust fluid handling and integration are priorities.

Product profile

•     Resolution and drop size: Optimized for hot melt fluids with resolutions typically listed up to 400 dpi or 450 dpi depending on variant and configuration; typical nominal drop size is around 80 pL. This combination targets reliable jetting of viscous hot-melt materials while preserving image quality at practical production speeds
•     Channel count and nozzle layout: 256 jets (organized across four independently driven slices, typically 64 channels per slice), arranged in a single line with consistent nozzle spacing to enable precise, high-density printing. This supports high jetting throughput for continuous production.
•     Fluids and environment: Specifically designed for hot-melt fluids; drive electronics and fluid management are integrated on-head, reducing assembly complexity and enabling more compact system designs. The head is compatible with the fluids Fujifilm certifies for hot-melt applications.

Key considerations for purchasing

•     Application fit: If your process uses hot-melt inks for packaging, lamination-like coating, or specialty graphics where solvent or UV-curable inks are not used, this head is aligned with those needs. For aqueous/solvent/UV-curable workflows, consider other Galaxy variants (e.g., 256/30 HM or JA/80 AAA lines) that are optimized for those chemistries.
•     Drop size vs. resolution trade-off: 80 pL drops at 256 jets can provide a balance between print quality and jetting reliability on hot-melt materials; verify your target resolution and fluid viscosity with Fujifilm’s data sheets for exact ranges.
•     System integration: Because it comes as a complete assembly with reservoir and drive electronics, it can simplify system design but may require specific controller hardware and firmware compatible with your printer platform. Confirm the compatibility with your existing inkjet controller, power, and cabling standards.
•     Spare parts and service: Check availability of replacement jets, cables, and head cables, as well as warranty terms and service coverage. This can impact downtime and total cost of ownership in a production environment.

Quick comparison to related variants

•     Galaxy PH 256/30 HM: Higher nozzle density and smaller drop size options (30 pL) with capabilities up to 900 dpi in some configurations, still hot-melt focused. This variant targets finer detail at higher resolutions, potentially at higher cost or with different viscosity handling. If you need very high DPI for intricate graphics with hot-melt fluids, this could be a better fit.
•     Galaxy JA 256/80 AAA or 256/80 AAA: These are solvent/aqueous/UV-capable lines with 256 jets but different drop sizes and fluid compatibilities; suitable when you’re not using hot-melt fluids. If your application uses non-hot-melt inks, these heads are more appropriate.
•     Nova PH 256/80 AAA: Similar 256-jet architecture but positioned for broader industrial/commercial applications with different fluid support and DPI ranges; compare drop size and viscosity specs against your process.
