Function

• Handles communication between the main board and the internal peripherals
• Reads the sensors (encoder, media, temperatures, door open)
• Drives the auxiliary I/O (platen suction, fans, heating/drying modules)
• Distributes the control signals to the carriage and ink-system sub-boards
• Centralises and secures the machine-status feedback

Signs of wear

• Intermittent sensor errors (encoder, media, temperatures)
• Faulty or unstable platen suction
• Communication errors between the main board and peripherals
• Irregular or uncontrolled media heating/drying
• Unexpected machine stops with no obvious hardware cause
• Erratic carriage behaviour or encoder signal loss

Replacing this part restores the machine to proper working order.
