Canon BH-40 Color Print Head for PIXMA G2420 G2430 G3420 G3430

Canon BH-40 Color Print Head

The Canon BH-40 Print Head serves as the critical thermal inkjet delivery component for the Canon PIXMA G-Series MegaTank printer ecosystem. This field-replaceable unit contains the precision nozzle arrays required for cyan, magenta, and yellow ink deposition. It ensures consistent droplet volume and placement accuracy across various media types. Consequently, maintaining a functional print head is essential for preserving the manufacturer-rated 4800 x 1200 dpi resolution. This specific module facilitates the high-volume output capabilities inherent to the continuous ink supply system (CISS) architecture.

Key Features

• Integrated Tri-Color Architecture
  The component houses three distinct nozzle sets for CMY ink processing within a single modular housing to streamline maintenance.

• High-Density Nozzle Configuration

  • Optimized for thermal inkjet firing frequencies.
  • Minimizes banding during high-speed draft modes.

• CISS System Optimization
  The internal fluid channels are engineered to handle the constant pressure of a continuous ink supply without air ingestion.
