The Spectra Polaris PQ-512/15 AAA is a high
performance inkjet printhead designed for a broad
range of industrial and commercial printing
applications at resolutions up to 1000 dpi. Robust
construction and repairable design make it ideal for
solvent, UV and aqueous based wide format printers
built for demanding production environments.

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 Polaris PQ-512/15 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 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 PQ-512/15 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-512/15 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 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.
