Genuine Kyocera KJ4B-1200-RC 1200 DPI aqueous printhead with continuous nozzle-near ink recirculation for maximum reliability at ultra-high resolution. Delivers precise 2–4 pL droplets at 80 kHz, industry-leading productivity of 101.6 m/min and exceptional image quality for commercial, packaging and textile printing.
Product Overview
The Genuine Kyocera KJ4B-1200-RC (officially KJ4B-EX1200-RC) is Kyocera’s flagship high-precision recirculating aqueous inkjet printhead designed for the most demanding 1200 DPI industrial applications. Featuring continuous nozzle-near ink recirculation, a large monolithic piezoelectric actuator and optimized fluid architecture, this printhead delivers outstanding jetting stability, precise small-drop control and industry-leading productivity. The recirculation system continuously moves ink past the nozzles, effectively eliminating drying, clogging and pigment sedimentation even with fast-drying or high-solids aqueous inks. Combined with a standard water-cooling system and integrated heater, the head maintains stable temperature and viscosity during long continuous runs. With 5,116 nozzles across a 108.3 mm print width, a maximum drive frequency of 80 kHz and variable droplet volumes from 2.0 to 4.0 pL, the KJ4B-1200-RC achieves print speeds up to 101.6 m/min while producing exceptionally sharp, high-resolution images. Ideal for commercial printing, packaging, labels, textile and other high-end aqueous applications where both image quality and production uptime are critical.

Technical Precision & Operational Advisory
- Electrostatic Discharge (ESD) Protection: Always wear a properly grounded ESD wrist strap when handling the printhead. The high-precision piezo actuator and electronics are extremely sensitive to static electricity.
- Power Isolation Warning: Completely power off the printer and disconnect the main power supply before connecting or disconnecting the FFC ribbon cable or any fluid lines.
- Cable Replacement Protocol: It is strongly recommended to replace the head cable with a new genuine cable at the same time as installing the new printhead to ensure reliable signal transmission.
- Fluid System Preparation: Thoroughly flush the entire ink system with approved cleaning fluid before first use. Only use Kyocera-compatible aqueous inks within the specified viscosity range.
- Temperature & Viscosity Control: Use the integrated heater and water-cooling circuit to maintain stable ink viscosity (5.0–6.0 mPa·s) for precise small-drop formation during extended high-resolution production.
