The H9740 (1631) Encoder Sensor is an upgraded optical decoding component developed for large-format printers. It is designed for precise motion detection and stable signal transmission, helping keep printhead carriage positioning accurate and print quality consistent even during high-speed printing.
This model is suitable for multiple large-format printer models and features dual A/B channel output for accurate motion control. Compared with the H9730 model, it offers improved optical stability. It can be supplied with or without a signal cable, and its durable PCB plus heat-resistant casing help support long-term use.

Before installing or replacing the encoder sensor, turn off the printer power. Make sure the optical window is aligned with the encoder strip, and keep a 0.3–0.6mm gap between the sensor and strip. The encoder strip should remain clean and free of dust.
Note: The H9740 (1631) is an enhanced version of the H9730, offering better decoding precision and signal stability for high-speed, large-format printers.
