Troubleshooting
When an Error Message Appears on the Client Computer
This section describes the main possible causes and solutions for error messages displayed on the client computer when the TWAIN Driver is used.
Note
❒If an error message that is not included in this section appears, turn off the main power switch of the machine, and then turn it on again. If the message still appears, note the content of the message and the error number (if dis- played), and contact your service representative. For information about how to turn off the main power switch, see General Settings Guide.
