There is no workaround, it isn't an option, unless you count copying a book and then scanning the output as a workaround.
Xerox is basically a North American division, and FujiXerox does the rest of the world (Yes, that is over generalizing)
Outside of North America, things like School Textbooks don't have the cost associated like here in North America, IP laws are also different.
So Xerox probably doesn't have the function to eliminate the possibility to be sued for abetting infringement, just like if you try to copy money it won't let you, and if you manage a scan of money, even programs like Photoshop won't open it.
To get an official response from Engineers, you would need to call and go through 2nd level support. But I wouldn't bother, it won't be added to the device and the answer will just be "It doesn't, because reasons, make a copy, scan that"
