Product Overview
The Genuine New Spectra Polaris PQ-512/35 AAA (also referenced as PQ-512/35pl) is an authentic factory-original industrial piezoelectric drop-on-demand (DoD) inkjet printhead manufactured by Fujifilm Dimatix under the Spectra brand. Built on the proven reliability of the Spectra Nova and Galaxy platforms and the Q-Class architecture, the Polaris PQ-512 AAA family employs durable materials and a field-repairable design to deliver long service life, high throughput, and consistent drop placement accuracy in demanding production environments.
The PQ-512/35 AAA features 512 independent addressable channels arranged in multiple rows. It supports single-color operation at 200 dpi nozzle spacing (127 µm) or two-color operation at 100 dpi spacing (254 µm), achieving maximum resolutions up to 800 dpi. Utilizing Fujifilm Dimatix’s proprietary VersaDrop™ binary jetting technology, it delivers a calibrated native drop size of 35 picoliters (35 pL) at a nominal velocity of 8 m/s, with adjustable binary operation capable of producing droplet sizes up to 80 picoliters. Maximum firing frequency is 30 kHz for 35 pL drops and 13 kHz for 80 pL drops. The printhead supports fluid viscosities of 8–20 centipoise and operating temperatures up to 60 °C, accommodating UV-curable, organic solvent, and aqueous ink chemistries.
Key operational advantages include configurable 1-color or 2-color modes, field-replaceable 256-channel modules without special tools or recalibration, dual-ported fluid interfaces for priming, flushing and recirculation, integral mounting bezel with precision registration points, and built-in heaters with temperature sensors for precise viscosity control. These characteristics make the PQ-512/35 AAA a preferred genuine OEM replacement for wide-format solvent, UV and aqueous industrial printers requiring balanced image quality and production speed.

Technical Precision & Operational Advisory
Installation must be performed by a qualified field service technician following the printer and printhead manufacturer’s procedures.
- Electrical power isolation: Completely power down the printing system and disconnect carriage driver power before attaching or removing electrical connectors to prevent damage to the printhead or mainboard.
- ESD protection: Service personnel must wear grounded anti-static wrist straps. The piezo actuators and logic circuits are sensitive to electrostatic discharge.
- Fluid system preparation: Thoroughly flush ink supply lines with approved cleaning fluid and replace inline filters before connecting the new printhead. Contaminated ink or debris will immediately clog channels.
- Ink compatibility verification: Confirm the ink chemistry (UV, solvent or aqueous) matches the printer’s fluid system and the printhead’s approved range (8–20 cP). Incorrect viscosity or chemistry will cause jetting failure or permanent damage.
- Meniscus / sub-atmospheric pressure: Maintain correct fluid pressure and recirculation settings as specified by the printer OEM. Improper meniscus control leads to nozzle dropout or flooding.
- Orientation & mounting: Use the integral precision registration points on the mounting bezel. Do not force alignment. Carriage slant and voltage waveform must be set according to the printer service documentation.
- Nozzle protection: Keep the nozzle plate protected until the printhead is installed and ready for priming. Never wipe the nozzle plate with unapproved materials.
- Non-returnable once exposed: Once the factory seal is broken or the printhead has been exposed to ink, it is considered used and cannot be returned.
