Kyocera KJ4A-QA Industrial Printhead

Key Features & Benefits

• 600 dpi Native Resolution

  2,656 nozzles (2,558 effective) across 108.25 mm print width produce sharp text, fine lines, and smooth gradients—ideal for high‑quality graphics and detailed coding.
• Multi‑Drop Gray Level Technology

  Variable drop sizes (3 / 6 / 13 pL) with multiple gray levels enable precise color control, fine detail rendering, and uniform coverage on diverse substrates.
• High‑Speed Industrial Performance

  Max drive frequency 20 kHz supports print speeds up to 50 m/min at full resolution, balancing quality and throughput for mid‑to‑high volume production.
• Optimized for UV & High‑Viscosity Inks

  Designed for UV‑curable inks (viscosity 6–7 mPa·s); built‑in filters and heater ensure stable ink supply and consistent jetting in demanding environments.
• Compact & Durable Industrial Design

  Dimensions 200 × 25 × 59.3 mm, weight 420 g; rugged construction with isolated channels minimizes clogging and extends service life in continuous operation.
