1. Click “Start” → “Control Panel”.
2. Double-click “System”.
3. Select “Hardware” tab and click “Device Manager”.
4. Double-click “Ports (COM & LPT)”.
If the Sharp COM Redirection Software icon is shown, Sharp COM Redirection Software has been
installed.
If there is a yellow exclamation mark (!) or question mark (?) on the Sharp COM Redirection Software
icon, there is a possibility that the installation has failed, COM numbers are duplicated or there is a
conflict with another driver resource.
In such a case, it is necessary to delete Sharp COM Redirection Software once and then reinstall it.
