Frequently Asked Questions
What is the difference between KJ4B-YH and KJ4B-QA?
Both are 600 dpi, 2,656-nozzle, aqueous-ink KJ4B heads. The YH runs at 40 kHz (vs 30 kHz for the QA) and reaches 100 m/min (vs 75 m/min) — making the YH the higher-speed variant. The YH also has slightly different physical dimensions (200 × 30 × 60.9mm vs 200 × 25 × 59.3mm) — they are not physically interchangeable. Always check your printer's service documentation for the specified model.
Is this listed as "UV" on your site? The KJ4B-YH is water-based, not UV.
You are correct — this is a water-based / aqueous printhead. The product title was incorrectly labelled; this listing is the genuine Kyocera KJ4B-YH for water-based inks, as confirmed in the specifications above. The Kyocera KJ4A series are the UV heads.
Do you ship Kyocera KJ4B-YH printheads to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Our Miami location is ideal for Latin American Canon/Océ production operations using freight forwarders in the Doral area.
