Genuine original Xaar 501 GS8 UR piezoelectric printhead with TF Technology recirculation optimised for UV-curable inks delivering maximum reliability in industrial wide-format graphics and coding production.
Product Overview
The Genuine Xaar 501 GS8 UR Printhead is a high-performance piezoelectric drop-on-demand printhead specifically engineered for UV-Curable ink applications with Ink Recirculation (TF Technology). Built upon Xaar’s PrecisionPlus actuator architecture and featuring High Flow TF Technology along with Ultra High Viscosity Technology, it enables continuous ink recirculation directly behind the nozzle plate. This prevents pigment sedimentation, eliminates micro-bubbles, ensures instant priming, and maintains optimal nozzle temperature and health in demanding continuous UV production settings. Featuring 500 active nozzles in a single-row layout at 180 npi native density across a 70.5 mm print swathe, it supports greyscale firing modes from 8 to 40 pL drop volumes across 6 grey levels. Constructed with UV-resistant materials and equipped with a WFG Nozzle Guard, it delivers maximum operational uptime and exceptional image detail in industrial UV inkjet platforms.

Technical Precision & Operational Advisory
- Electrostatic Discharge (ESD) Protection: Always wear a grounded ESD wrist strap and work on an ESD-safe surface when handling sensitive electronic parts. Piezoelectric actuators are highly sensitive to static discharge.
- Power Isolation Warning: Fully power off the equipment and disconnect main power sources before replacing parts or connecting flexible flat cables (FFC).
- Cable Replacement Protocol: It is strongly recommended to replace flexible flat cables (FFC) and related connectors with new genuine parts during every printhead installation to ensure reliable signal integrity.
- Recirculation Fluid System Setup & Light Shielding: Ensure proper loop connections for High Flow TF Technology recirculation. Verify external ink filtration before the inlet, as this model lacks an internal in-line filter. Protect nozzles from ambient light and stray UV curing radiation to avoid premature curing inside the printhead.
- Professional Installation: It is strongly recommended to have replacement performed by a certified technician following standard technical protocols.
