Step 2: Confirming the computer's name and the user name
Confirm the computer name and the user name for the computer you will send scanned documents to. Write down the confirmed information.
On the Apple menu, click [About This Mac].
Click [System Report...].
In the left pane, click [Software], and then confirm the computer name and user name under "System Software Overview:".
The computer name is displayed under [Computer Name].
The user name is displayed under [User Name].
Depending on the operating system or security settings, you might be able to specify a user name that does not have a password assigned. However, we recommend that you select a user name that has a password.
To confirm the IP address on the Apple menu, click [System Preferences...], and then click [Network] on the System Preferences window. Then click [Ethernet]. The address displayed in the IP address field is the IP address of the computer.
