Genuine New Kyocera KJ4A-AL UV Inkjet Printhead

Product Overview

The Genuine New Kyocera KJ4A-AL UV Inkjet Printhead is an authentic, factory-original industrial piezoelectric drop-on-demand (DoD) jetting assembly. Specifically designed for advanced industrial applications where space and weight are critical, the KJ4A-AL features a compact drive design without sacrificing the robust performance expected from Kyocera's KJ4A series. It is highly suited for heavy-duty single-pass and multi-pass UV printing systems.

Equipped with an active print width of 108.25 mm and powered by 2,656 precision-engineered channels, this native 600 dpi printhead ensures high-density, photographic-quality output. Delivering precise droplet sizes, the assembly is optimized for sharp image details, superior text clarity, and production line speeds of up to 50 meters per minute. The KJ4A-AL includes an internal heater to compensate for high-viscosity UV ink formulations, stabilizing the ink's rheology immediately before jetting, while its internal filtration system protects against micro-particulates.

Key Features & Operational Advantages

• 100% Genuine Kyocera OEM: Authentic factory-new unit ensuring precise drive signal matching, optimal drop trajectory, and maximum operational lifespan.
• Compact Drive Architecture: Space-saving design ideal for modern, streamlined carriage systems and compact single-pass digital presses.
• High Resolution 600 dpi Output: Delivers incredibly sharp and detailed images powered by a high-density 2,656-nozzle array.
• Advanced Thermal Management: Integrated internal heater maintains optimal ink viscosity for stable, continuous drop generation in demanding industrial environments.
• High-Speed Performance: Operates efficiently at high drive frequencies, allowing for rapid linear printing speeds without compromising print quality.

Technical Specifications

Operational Advisory & Installation Guidelines

• Qualified Field Service Technician Required: Mounting, carriage slant alignment, voltage parameter tuning, and fluidic installation must strictly be performed by certified service engineers.
• Electrical Power Isolation: Always turn off the printing system completely and disconnect carriage driver power before attaching or removing electrical connector cables to prevent mainboard shorting.
• Electrostatic Protection (ESD): Service personnel must wear grounded anti-static ESD wrist straps during handling to shield internal piezo actuators and logic circuits from static shock.
• Temperature Calibration: Ensure the internal heater system is configured to match the exact viscosity-temperature profile provided by your ink vendor before initiating jetting sequences.

Compatible Printers or Equipment

Widely integrated into industrial digital presses, compact single-pass label converters, wide-format UV flatbeds, and custom hybrid printing machines utilizing Kyocera KJ4A-AL architecture. (Please verify head mounting pin layout, voltage requirements, and printer firmware level prior to installation.)
