The Genuine New Kyocera KJ4A-0300 UV Inkjet Printhead is an authentic industrial-grade 300 dpi dual-color piezoelectric drop-on-demand jetting assembly designed for high-speed single-pass and multi-pass printing applications. Featuring 2,656 active nozzles across a 112.35 mm swath, a 30 kHz drive frequency, variable drop sizes (4, 6, 10, 14 pL), and line speeds up to 158 meters per minute, it delivers exceptional throughput, color flexibility, and thermal efficiency for UV-curable inks.
The Genuine New Kyocera KJ4A-0300 UV Inkjet Printhead (MPN: KJ4A-0300, Distributor SKU: PPHKY82406) is an authentic, factory-original industrial piezoelectric drop-on-demand (DoD) jetting assembly manufactured by Kyocera Corporation in Japan. Engineered for high-speed industrial printing systems requiring dual-color output from a single unit, the KJ4A-0300 features 2,656 active channels configured as 2 x 1,328 nozzles across an extended 112.35 mm active print swath. Operating at a maximum drive frequency of 30 kHz, it achieves extraordinary production line speeds of up to 158 meters per minute at 300 x 300 dpi native resolution. Utilizing multi-drop grayscale technology, it generates calibrated drop volumes of 4 pL, 6 pL, 10 pL, and 14 picoliters, enabling precise highlight control alongside dense solid coverage. Constructed with integrated thermal control, internal heaters, and built-in fluid filtration, the unit maintains optimal ink viscosity (typical 7.0–7.5 mPa·s) and protects against micro-particle contamination when driving high-viscosity UV-curable inks.

Operational & Installation Advisory
- Note: For optimal integration, mounting, carriage slant alignment, voltage parameter tuning, and fluidic installation must strictly be performed by qualified field service engineers.
- Note: Always completely isolate electrical power and replace head ribbon cables before connecting the new printhead to avoid catastrophic mainboard shorting.
- Note: Service personnel must wear grounded anti-static ESD wrist straps during handling to shield internal piezo actuators from static shock.
- Note: Thoroughly flush ink supply lines with approved cleaning solution and replace inline filters prior to connecting the printhead.
