Brother DCP-8040 User Manual page 40

When you put paper in the manual feed tray, please remember
the following
■
The side to be printed on must be face up.
■
Put the leading edge (top of the paper) in first and push it
gently into the tray.
■
Make sure that the paper is straight and in the proper
position on the manual feed tray. If it is not, the paper may
not be fed properly, resulting in a skewed printout or a paper
jam.
■
Do not put more than one sheet of paper or envelope in the
manual feed tray at any one time, or it may cause a jam.
