Availability: In stock

The Kyocera KJ4B for DGI Spirit / Poseidon is the genuine original DGI-specific variant of Kyocera's KJ4B industrial inkjet printhead — a dual-colour, 300 dpi aqueous head engineered specifically for DGI's high-speed dye-sublimation transfer printer platform. Based on the KJ4B-0300 architecture with 2,656 nozzles across a 112mm print swathe (2 × 1,328 nozzles per channel), it delivers variable drop volumes from 5 to 18 pl at up to 30 kHz, achieving print speeds up to 120 m/min. The DGI Poseidon uses 2 or 3 of these heads in its dye-sublimation configuration, reaching maximum printing resolutions of 600 × 1,200 dpi. Every KJ4B (DGI variant) we sell at Digiprint USA is 100% genuine original Kyocera — manufactured in Japan.
DGI-specific variant — not interchangeable with Standard or MS/EFI Reggiani versions. The KJ4B family exists in multiple hardware variants configured for specific printer manufacturers. This DGI Spirit/Poseidon version is hardware-tuned for DGI's drive electronics and ink system. It is not the same as the KJ4B-QA Standard (for Xerox Rialto, Atexco Vega), the KJ4B-0300 Standard (for MS Italy), or the KJ4B-YH (high-speed 40kHz variant). Always confirm your DGI printer model and serial number before ordering. Contact our team if unsure.

About the DGI Poseidon
The DGI Poseidon is an industrial dye-sublimation transfer printer equipped with 2 or 3 Kyocera KJ4B heads in a scanning carriage architecture. It supports water-based dye-sublimation inks in 4 or 6-color configurations (CMYK + Lc/Lm/Fm/Fy), with a maximum printing width of 1,880mm and maximum resolution of 600 × 1,200 dpi. Key production features include a dedicated capping station that maintains humidity to prevent nozzle drying, a head collision sensor for printhead safety, an individual degasser system that removes micro-bubbles from each head separately, and an eco-mode for reduced power consumption between runs. The Poseidon supports mini-jumbo rolls for extended unattended production.

Frequently Asked Questions
Why is the DGI variant different from other KJ4B-0300 printheads?
The KJ4B-0300 is a 300 dpi dual-colour head platform used by multiple printer manufacturers. However, each OEM configures the head's drive electronics, waveforms, and ink system interface to their specific printer architecture. The DGI Spirit/Poseidon version is hardware-configured for DGI's ink delivery system and carriage electronics — installing a KJ4B-0300 Standard (configured for MS Italy printers) in a DGI Poseidon will result in jetting failure. Always confirm the DGI-specific variant is what you need before ordering.
How many printheads does the DGI Poseidon use?
The DGI Poseidon uses 2 or 3 Kyocera KJ4B heads depending on configuration. Since each head is a dual-colour unit (2 channels × 1,328 nozzles), a 2-head configuration supports 4-colour printing (CMYK) and a 3-head configuration supports 6-colour printing (CMYK + additional spot colours such as Fluorescent Pink, Fluorescent Yellow, Light Magenta, or Light Cyan). When ordering a replacement head, confirm which head position is affected and how many heads your specific Poseidon configuration uses.
What is the difference between the DGI Spirit and DGI Poseidon?
Both the DGI Spirit and DGI Poseidon use DGI-specific Kyocera KJ4B printheads for water-based dye-sublimation transfer printing. The Poseidon is DGI's industrial-tier high-speed platform (up to 210 sqm/hr) equipped with advanced features like an individual degasser system, head collision sensor, dedicated capping station, and mini-jumbo roll support. Contact our team with your specific model name and serial number to confirm which head position and quantity you need before ordering.
Do you ship the DGI KJ4B printhead to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse before 2PM EST. Our Miami location is ideal for Latin American DGI Poseidon and Spirit production shops using freight forwarders in the Doral area.
