Alias: Engine Control Board, Main Engine PCB for ComColor X1 Series

Description

This is an original pulled used engine control PCB for the Riso ComColor X1 high‑speed FORCEJET inkjet production printer. It acts as the core controller of the entire print engine, governing printhead drive signals, paper transport, vacuum system, ink supply, motor actuation and sensor feedback. The board is removed from working donor machines and fully tested before shipment, ready for direct replacement to resolve engine communication and control failures.
