Errors That Occur When the Control Panel Downloads Data from the Controller at Startup
Some of the graphic data used in the control panel display is model-specific. Model-specific components are
stored in the controller board of the MFP.
During startup, the control panel checks if it is necessary to update the model-specific data. If it is necessary, the
control panel downloads the data from the MFP controller board and installs it in the control panel.
During update, a dialog appears to inform you that the settings are being changed. When the update process is
completed, a dialog indicates whether update was successful or not.
Error code Explanation
E1 An error has occurred when downloading data from the controller board of the MFP.
E2 An error has occurred when installing data on the control panel.
