Brother MFC-J480DW cuts off top margin

In Linux, my Brother MFC-J480DW cuts off top margin when used with A4 paper, even if all settings are set to A4.

To make it work, I had to edit /opt/brother/Printers/mfcj480dw/inf/brmfcj480dwrc file (that's the path in Gentoo, it could be different in other distributions).

And change:
