Genuine Printhead Dimatix SAPPHIRE QS-256/30 AAA
Sapphire QS-256/30 AAA printhead delivers best-in-class jetting accuracy combined with versatile grayscale operation. Its lightweight, thin-profile design and configurability plus support for a broad range of ink formulations makes this printhead model particularly suited to scanning printer architectures and applications.

Dimatix continues building upon its long history of excellent dot placement accuracy, channel-to-channel uniformity, low cross talk, and high-frequency/high-productivity with the Q-Class Sapphire printhead family.

The Sapphire QS-256/30 AAA printhead features 256 independent channels, arranged in a single row of nozzles at 100 dots-per-inch spacing. It is designed to eject adjustable 30 to 80 picoliter drops in binary jetting mode or a 30-picoliter fundamental drop in grayscale mode. This is done at a nominal 8-meter per second drop velocity when jetting fluids in the 10 to 14 centipoise range.

Each 256-channel Sapphire printhead is offered with an integral temperature sensor and a configurable, dual-ported fluid interface comprised of O-ring face mounts or barbed fittings to facilitate fast flushing or recirculation of inks.
Printhead operational temperature can be up to 90° C. The driver chip is double buffered to support the Sapphire QS-256/30 AAA high-speed jetting capability
