Genuine original Xaar 502 GS8 O piezoelectric printhead engineered for reliable high-quality industrial printing with oil-based inks in coding, marking, packaging and graphics applications.
Product Overview
The Genuine Xaar 502 GS8 O is a high-precision greyscale piezoelectric drop-on-demand printhead engineered for industrial coding, marking, and product printing applications using oil-based inks. Featuring a native base drop size of 8 pL (greyscale range 8–40 pL across up to 6 levels), the GS8 variant excels at producing high-contrast fine text, crisp 1D/2D barcodes, and detailed graphics on porous and semi-porous packaging substrates. With 500 active nozzles delivering a native 180 npi resolution across a wide 70.5 mm print swathe, it reduces printhead stitching requirements and maximises line throughput. Built on Xaar’s PrecisionPlus actuator architecture, the Xaar 502 GS8 O ensures exceptional drop placement accuracy, uniform drop formation, and robust performance in demanding production environments.

Technical Precision & Operational Advisory
- Electrostatic Discharge (ESD) Protection: Always wear a grounded ESD wrist strap and work on an ESD-safe mat when handling the printhead. Piezo actuators are highly sensitive to static voltage spikes.
- Power Isolation Warning: Fully disconnect printer power before attaching or removing FFC ribbon cables or fluid connections.
- Cable Replacement Protocol: Always install brand-new flexible flat cables (FFC) when replacing the printhead to maintain signal integrity and avoid electrical short circuits.
- Fluid Compatibility: Use only approved oil-based industrial inks. Ensure proper fluid filtration and viscosity control prior to priming.
- Orientation Flexibility: Supports horizontal, vertical, and angled mounting configurations depending on packaging line requirements.
Compatible Equipment & Applications
| Category | Details / Compatible Systems |
|---|---|
| Printer Compatibility | Compatible with industrial coding & marking systems, secondary packaging printers, and OEM coding platforms integrated with Xaar 502/50X drivers (e.g., MapleJet and equivalent industrial coding systems). |
