Polaris PQ-512/15 Printhead
PDS00035 Rev. 02 11/19/09
Building upon the legendary reliability and performance of
the Spectra Nova and Galaxy printheads, the Polaris PQ-512
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 offers even greater
jetting performance, nozzle packing density, and
configuration flexibility.
The Polaris PQ-512/15 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 10 to 14 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 Printhead is compatible with a broad range
of inks, including UV-curable, aggressive organic solvent
inks and associated maintenance fluids.
The unique design of Polaris PQ-512/15 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
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 flushing and ink recirculation. Heaters and
temperature sensors allow precise control of ink
viscosity at jetting temperatures up to 60°C.
