Kyocera KJ4B-0300 Inkjet Printhead

The Kyocera KJ4B-0300 inkjet printhead is designed for industrial inkjet printing systems that use water-based (aqueous) inks. Featuring two independent ink channels and 2,656 nozzles, this dual-colour printhead supports efficient ink delivery for high-speed printing applications.

With a native resolution of 300 × 300 dpi and a maximum drive frequency of 30 kHz, the Kyocera KJ4B-0300 supports printing speeds of up to 120 m/min. Its variable drop volumes of 5, 7, 12, and 18 pl provide multiple ink deposition options for different printing requirements. The 18 pl drop volume is available at drive frequencies of up to 20 kHz only.

An integrated heater helps control ink temperature, while internal filters help prevent foreign objects in the ink supply from reaching the printhead. These features make the Kyocera KJ4B-0300 a suitable option for compatible industrial printing systems using aqueous inks.
