Brother HL-7050 Series User Manual page 48

Before you print envelopes, you must 'fan' the stack to
avoid paper jams and misfeeds.
Figure 1-18
Do not load different types of paper at the same time in the
paper tray because it may cause paper jams or misfeeds.
Do not print envelopes using duplex printing.
For proper printing, you must choose the same paper size
from your software application as the paper in the tray.
If your application software does not allow you to select the
paper size in its Print menu, you can use the control panel
Menu buttons to go to the PAPER menu to change the
paper size. For more information, see Chapter 3.
