  • By factory default, the following switches of the DIP switch [A] on the micro computer board are set to ON: No.1, No.3, No.6 and No.7. When installing the operation panel unit, make sure that the DIP switch setting is correct for the MFP on which you are installing the panel.
  • The correct DIP switch setting depends on the MFP. Note the DIP switch settings of the old operation panel unit before replacing, and apply the same settings to the new Smart Operation Panel. Below is example for DIP switch settings when the following switches are set to ON: No.1, No.3, No.6 and No.7 (This is the factory default setting of a service part)

    • 0 (OFF): The SC is displayed on the operation panel when SC672/SC673 occur.
    • 1 (ON): If the error is caused by the software defect when SC672/SC673 occur, automatically reboot is performed and the SC is reset. If the error is caused by the hardware defect when SC672/SC673 occur, the SC is displayed on the operation panel.
  • After replacing the operation panel unit, make sure that the latest version of the firmware is installed on the Smart Operation Panel. Update it if necessary (Updating the Smart Operation Panel).
