Mutoh Iris 43 Wide Mainboard on wide format printer

The Mutoh Iris 43 Wide Mainboard is the central control board of a wide‑format inkjet printer, integrating power regulation, drive logic, and communication with the printer’s motor and print head subsystems. Common failure points on this class of boards include degraded power supply components (capacitors, voltage regulators), burnt or cracked traces from mechanical vibration, and firmware corruption that can trigger “board not found” errors. First‑check diagnostics: verify 12 V/5 V rail continuity and ripple; inspect the board for visible burn marks or loose solder joints; and review any error codes displayed on the printer’s status panel or logged in the service interface.[oss-gpt-20b]
