Using VersaDrop jetting technology, the printhead is capable of adjustable binary operation at drop sizes up to 80 picoliters with resolution up to 800 dpi. • Building upon the legendary reliability and performance of the Spectra Nova and Galaxy Printheads, the Polaris PQ-512 AAA family of printheads uses field proven materials and a repairable design to deliver a long service life and consistent output. And by leveraging the inherent flexibility of the Q-Class platform, the Polaris PQ-512 AAA offers even greater jetting performance, nozzle packing density, and configuration flexibility. • The PQ-512/35 AAA Printhead is compatible with a broad range of inks, including UV-curable, aggressive organic solvent and aqueous inks and associated maintenance fluids. • The unique design of Polaris PQ-512/35 AAA Printhead allows each 256-channel module to be replaced and accurately registered in the field with no special tools or recalibration. An integral mounting bezel with precision registration points enables drop-in alignment with other carriage features. • Two electrical connectors contain eight serial data supports fire frequencies in excess of 50 kHz. • The flexible fluid interface allows single and two-color operation. Each 256-channel module is dual ported to facilitate easy priming, flushing and ink recirculation. Heaters and temperature sensors allow precise control of ink viscosity at jetting temperatures up to 60°C.Features: • 35 picoliter nominal drop size; • 512 individual addressable nozzles; • Incorporates VersaDrop™ binary jetting capability; • Exnt channel-to-channel uniformity; • High frequency continuous operation; • Designed for long service life; • Supports UV-curable, solvent, and aqueous-based inks; • Configurable for single- and two-color operation; • Integral mounting bezel with precision features; • Optimized for high viscosity jetting fluids; • Built-in heaters and temperature sensors; • Operation up to 60°C [140°F]; • Simplified field repair with no special tools required.
