Toshiba CF3R vs CF6R Printhead Core Differences

I. Basic Parameter Comparison

II. Core Differences Analysis

1. Core Performance: Speed and Droplet Control Generation Upgrade
   • CF6R is an upgraded product of CF3R, with a 50% improvement in printing efficiency. This is achieved by increasing the ejection frequency from 9.2kHz to 12kHz, paired with a 1.5x faster driving algorithm, significantly improving the output capacity of a single printhead.
   • Droplet Control Logic: CF3R supports a wide range adjustment of 3-20pL (6 grayscale levels), suitable for fine artistic printing; CF6R uses a 6pL native droplet with 3-drop combination technology (6/12/18pL), which, while reducing the grayscale levels, achieves faster speeds with high-frequency ejection, balancing both precision and efficiency.

1. Structural Design: Compatibility and Cooling Balance
   • Both have identical size, electronic interfaces, and pipeline layouts. The CF6R can directly replace CF3R without altering the printer structure.
   • Cooling design is water-cooled, but CF6R has stronger heat dissipation compatibility due to high-frequency operation. It features built-in temperature sensors and a water-cooling module for closed-loop control, allowing it to handle long-term high-load operations (e.g., PCB mass production, high-speed corrugated printing).
2. Application Scenarios: Precise Matching of Demand Differences
   • CF3R Advantage Scenarios: Relies on high precision, such as ceramic/glass decoration (requires 3-4pL small droplets for fine texture), anti-counterfeit labels (high grayscale gradients), and high-viscosity ink printing (such as ceramic ink circulation stability).
   • CF6R Advantage Scenarios: Focused on production capacity in industrial fields, such as UV corrugated board printing (1.5x speed boost), PCB coding and marking (high-frequency ejection for assembly lines), and wide-format roll printing (dual-channel mode for high-speed equipment).
3. Technical Details: Trade-offs in Iteration
   • The 6-level grayscale and 3-20pL wide droplet range of CF3R provides an advantage in artistic printing, but its stability is weaker under high frequencies. CF6R sacrifices some grayscale levels in exchange for 12kHz high frequency and droplet combination flexibility, making it more suitable for industrial-scale production.
   • Both maintain the full nozzle ink circulation technology to prevent pigment sedimentation. However, CF6R further optimizes compatibility with UV ink (e.g., matching curing speeds).
