So from here, how do I adjust the settings to be able to either scan to email or scan to the only computer attached to the network?
Have you tried reading the post that made this thread be marked as Solved? Do that
Currently when I try scanning to network option, it says I need to set up an address book. But I did already set up the address book (for scan's).
If you setup the addressbook for email and haven't set up email then it won't work, it also won't work if you are going into the wrong scan option at the printer. We can't guess what you have or have not done and we can't guess as to your Operating system or computer literacy. You need to be very specific.
