The Polaris PQ-512 AAA Printhead has 512 independent channels arranged in multiple rows at 200 dots-per-inch spacing for single color operation, or 100 dots-per-inch spacing for two colors operation.
Building upon the legendary reliability and performance of the 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 Polaris PQ-512/15 AAA, PQ-512/35 AAA and PQ-512/150 AAA printheads have 512 independent channels arranged in multiple rows at 200 dots-per-inch spacing for single color operation, or 100 dots-per-inch spacing for two color operation. The printhead is designed for binary jetting using a 15-picoliter native drop size with 8-meters per second nominal drop velocity for jetting fluids in the 8 to 20 centipoise range. Using VersaDrop jetting technology, the printhead is capable of adjustable binary operation at drop sizes up to 30 picoliters.
The Polaris PQ-512/15 AAA, PQ-512/35 AAA and PQ-512/150 AAA printheads are 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 AAA Printhead Series 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 lines that 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.
