The Kyocera KJ4A-TA (complete part number KJ4A-TA06ATB) is a genuine original UV inkjet printhead engineered for high-speed single-pass industrial printing. With 2,656 nozzles across a 108.25mm print swathe — approximately twice the width of a Ricoh GEN5 head — it delivers 600 × 600 dpi output at up to 50 metres per minute using UV-curable inks. Its integrated filters eliminate foreign objects in ink and the built-in heater manages viscosity under changing ambient temperatures. Every KJ4A-TA we sell at Digiprint USA is 100% genuine original Kyocera Japan.

Why the KJ4A-TA's 108mm Swathe Matters
At 108.25mm, the KJ4A-TA's print swathe is approximately equivalent to the combined width of two Ricoh GEN5 printheads. This wider swathe reduces the total number of heads required in a single-pass UV printer — lowering carriage complexity, hardware cost, and alignment overhead. For high-volume industrial applications such as label printing, offset surprint, and narrow-web packaging, this translates directly into faster throughput and lower per-head maintenance cost.
KJ4A-TA vs Other Kyocera KJ4A Variants
| Model | Ink Type | Resolution | Primary Use |

| KJ4A-TA (this listing) | UV-curable | 600 dpi | Labels, packaging, sign graphics, offset surprint |
| KJ4A-RH | UV / solvent | 600 dpi | UV flatbed and roll-to-roll single-pass |
| KJ4A-AA | Aqueous | 600 dpi | Water-based textile and industrial printing |
| KJ4A-0300 | Aqueous / UV | 300 dpi | High-speed single-pass, wider nozzle pitch |
Each KJ4A variant is optimised for a specific ink chemistry and printer type.

Frequently Asked Questions
What is the complete part number for the KJ4A-TA?
The complete Kyocera part number is KJ4A-TA06ATB (also referenced as KJ4A-TA06AT). The KJ4A-TA designation refers to the series; the full code includes the drop volume and configuration specifications. When ordering, confirm the full part number matches your printer's service documentation.
How many nozzles does the KJ4A-TA have?
The KJ4A-TA has 2,656 nozzles in a 2 × 1,328 channel configuration across a 108.25mm print swathe. At 600 dpi with a 0.042mm nozzle pitch, this is approximately twice the effective width of a Ricoh GEN5 printhead — reducing overall head count in single-pass UV printer designs.
What drop sizes does the KJ4A-TA support?
The KJ4A-TA supports variable drop volumes of 6, 7, 11, and 14 picoliters. This multi-drop capability allows the head to produce greyscale output with smooth gradients and fine details while maintaining the 20kHz maximum drive frequency at up to 50 m/min.
Is the KJ4A-TA compatible with my EFI Reggiani or Xerox Rialto printer?
The KJ4A-TA is compatible with multiple EFI Reggiani models (ReNOIR TOP, Compact 180, BLAZE) and the Xerox Rialto 900. Contact our team with your exact printer model and serial number to confirm the correct KJ4A-TA variant and configuration for your system before ordering.
