first off, are you scanning to a computer or trying to scan to email? What operating system are you using? How are you connected to the printer? If you are using windows 10 you may have to enter the user name as follows:


domiain\username   where domain= either the Windows domain your computer belongs to (if applicable) or the name of the computer if this computer is not part of a domain.


Find the computer name in system information, it will be the device name:
