A margin appears on the right side of the scanned document when using the Brother iPrint&Scan application on my Android™ mobile device.
The cause of this situation is the Scan Settings within the Brother iPrint&Scan application.
If the Scan Settings are set as "Scan Type: Color(Fast)" and "Document size: 3.5" x 5" (9 x 13 cm)", a margin will appear on the right side of the scanned document.
To solve this problem, change the Scan Type from Color(Fast) to Color and try scanning again.
