Genuine Spectra Polaris PQR-512 85PL (PQ-512/85 AAA) Printhead – Original OEM
The Spectra® Polaris PQR-512 85PL (official model PQ-512/85 AAA) is a high-performance industrial piezoelectric drop-on-demand printhead manufactured by Fujifilm Dimatix. It is designed for a broad range of industrial and commercial printing applications, particularly textile and high-coverage production environments such as Kornit Avalanche and Storm systems.
The printhead features 512 independent channels arranged in multiple rows. In single-colour mode it operates at 200 dpi (127 μm nozzle spacing); in two-colour mode it operates at 100 dpi (254 μm spacing). It delivers a calibrated 80 picoliter native drop size with VersaDrop™ binary jetting capability, adjustable from 80 to 150 pL. Nominal drop velocity is 8 m/s. Maximum firing frequency is 20 kHz at 80 pL (10 kHz at 150 pL). Operating temperature is supported up to 60°C.
One Polaris PQR-512 85PL assembly consists of two Polaris PQR-256 85PL modules and uses a repairable design with field-proven materials for long service life and consistent output. The unit is dual-ported for efficient flushing and recirculation and includes integral heaters and temperature sensors.
We strongly recommend replacing the head cables when installing a new printhead. This is a genuine Spectra / Fujifilm Dimatix OEM product manufactured in the USA and carries the manufacturer warranty.

Technical Precision & Operational Advisory
Installation Warning
Installation, alignment and electrical connection must be performed by a qualified technician following the official printer manufacturer procedures. Incorrect handling can permanently damage the piezo channels or drive electronics.
- ESD Protection: Always use a grounded anti-static wrist strap when handling the printhead. Piezo actuators are highly sensitive to electrostatic discharge.
- Power Isolation: Completely power down the printer and isolate carriage drive power before connecting or disconnecting the printhead.
- Cable Replacement: It is strongly recommended to replace the head cables when installing a new printhead to avoid intermittent connection issues.
- Ink Compatibility: Use only UV-curable, solvent or aqueous inks approved for the specific system. Non-approved fluids can damage the head and void warranty.
- Handling Factory-Sealed Unit: Do not break the seal until ready for installation. Once the printhead has been exposed to ink or installed, it is considered used and cannot be returned.
- Warranty Exclusions: Damage caused by non-original inks, misuse, lack of maintenance, improper storage, or third-party components is expressly excluded from warranty coverage.
Compatible Models & Systems
The Spectra Polaris PQR-512 85PL is confirmed compatible with the following Kornit systems:
- Kornit Avalanche Hexa R
- Kornit Avalanche R series
- Kornit Storm Hexa
Recommendation: Always verify the exact part number on the existing printhead and consult the machine service documentation before ordering. Compatibility can vary by specific configuration and firmware revision.
