OEM Replacement Component
Fujifilm Dimatix Spectra Galaxy PH 256/80 AAA Printhead (80 pL)
OEM Part Number / Designation: Galaxy PH 256/80 AAA | High-Performance Industrial Piezoelectric Drop-on-Demand (DoD) Jetting Assembly
Product Overview
The Fujifilm Dimatix Spectra Galaxy PH 256/80 AAA is an authentic original equipment manufacturer (OEM) piezoelectric drop-on-demand (DoD) industrial inkjet printhead engineered for grand-format sign and graphics systems, industrial textile machinery, and high-speed packaging coding lines. Regarded as an industry workhorse for demanding continuous production environments, the Galaxy PH 256/80 AAA produces a calibrated fundamental droplet volume of 80 picoliters (pL) across 256 individually addressable inline channels configured along a single durable orifice plate.
Engineered with field-proven PZT piezoelectric shear-mode actuation and a chemically inert internal fluid path, the Galaxy PH 256/80 AAA is fully compatible with aggressive organic solvent, UV-curable, and oil-based ink chemistries. The unit features dual-ported fluid interconnects designed for continuous ink recirculation, rapid de-airing, and reliable meniscus priming. With an integrated heating element and high-accuracy internal thermistor, the assembly provides strict viscosity control up to 50°C (122°F), sustaining straight jet trajectory and uniform droplet velocity at continuous firing frequencies up to 20 kHz.

Key Features & Operational Advantages
- Robust 80 pL Area Coverage: High droplet mass provides rich color saturation, deep solid density, and fast coverage on wide outdoor mesh, backlit films, and heavy vinyl banners.
- 256-Channel Inline Geometry: 100 DPI native pitch offers high resolution in multi-head staggered carriages while doubling the channel density of 128-nozzle platforms.
- Dual-Port Recirculation & De-Air: Barbed inlet and return ports support continuous fluid circulation, preventing pigment settling in dense inks and eliminating micro-air entrapment.
- Broad Solvent & UV Latitude: Non-wetting nozzle plate surface and chemically resistant internal fluidics resist delamination and swelling from aggressive organic solvent carriers and UV monomers.
CRITICAL TECHNICAL & OPERATIONAL ADVISORY
1. Mandatory ESD Grounding: Piezoelectric PZT crystal channels and onboard driver shift registers are Class 1 ESD-sensitive components. Technicians must wear a grounded ESD wrist strap and work on a static-dissipative surface. Never insert or unseat data ribbon harnesses while carriage power or drive voltage is energized.
2. Protective Shipping Fluid Flushing: Factory printheads ship pre-wetted with protective storage fluid. Before introducing production ink, thoroughly flush the internal manifold with clean, filtered flushing solvent (minimum 0.2 micron absolute rating) to eliminate air pockets and prevent chemical precipitation.
3. Nozzle Plate Protection: Never wipe or abrade the orifice plate with dry wipers, paper towels, or metallic scrapers. Clean the plate surface solely using lint-free, solvent-compatible cleanroom polyurethane foam swabs, or rely on automated non-contact purging and vacuum wipe stations.
4. Negative Meniscus Vacuum Calibration: Piezo DoD heads require precise negative meniscus vacuum pressure (typically -1.5 to -3.0 inches of water column / mbar equivalent) to maintain a stable concave meniscus at each nozzle and avoid ink weeping or air ingestion during printing.

*Model Differentiation Note: This printhead is dedicated strictly to the Galaxy PH 256/80 AAA (80 pL native drop) specification. Although it shares the 256-channel architecture with the Nova JA 256/80 AAA, verify the specific mechanical mounting flange, carriage bezel alignment pins, and electrical ribbon pinouts used on your carriage chassis prior to installation.
Terms, Warranty & Customer Protection
Condition: 100% Brand New, Unopened Factory Original Genuine OEM Component in Factory-Sealed Anti-Static Packaging with Factory Storage Fluid Intact.
Warranty Scope: Covered by standard manufacturer DOA replacement protection against electrical continuity failures and physical manufacturing defects upon initial arrival. Operating longevity is governed strictly by ink filtration quality, fluid degassing, correct drive waveform tuning, and adherence to recommended purge and maintenance protocols.
Return Policy: Precision industrial electronic consumable. Due to sensitivity to electrostatic discharge, internal fluid priming requirements, and chemical contamination risks once unsealed, components that have been removed from their static-shielding bag, filled with ink, flushed with solvents, or energized cannot be returned or restocked under standard commercial terms. Please confirm your printer model and drop-volume specification with technical support prior to unsealing.
