Brother MFC-8440 B - Manual (Page 138)

10 - 2 MAKING COPIES
Temporary copy settings
You can improve your copies by using the Temporary Copy Keys:
Enlarge/Reduce , Contrast , Quality , Tray Select , Sort and
N in 1 (For MFC-8440) or Duplex/N in 1 (For MFC-8640D,
MFC-8840D and MFC-8840DN). These settings are temporary, and
the MFC returns to Fax mode 1 minute after it finishes copying. If you
want to use these temporary settings again, place the next original in
the ADF or on the scanner glass within that time. However, if you
have set the Mode Timer for Copy and Scan modes to 0 to 30
seconds, the MFC returns to the default settings after the number of
seconds that has been set for Mode Timer. (See Setting the Mode
Timer on page 4-5 and see Using the copy keys (Temporary
settings) on page 10-6.)
While the MFC is copying, incoming faxes will be received into
the memory instead of being printed.
