Brother all -in-one won't scan to email. Discussion in 'All Other Software' started by compconfused, Sep 5, 2010. Advertisement. I can't get my Brother MFC 5440CN to scan documents into email. The software is set up to default to Outlook Express (which I don't use) as the email application. Have tried to change the default (to what I do use, Mozilla Firefox/Gmail) through the Brother Control Center 2.0 dashboard.
