Brother MFC 8220 - Manual (Page 125)

MAKING COPIES 10 - 4
Using the Copy keys
(Temporary settings)
When you want to change the settings only for the next copy, use the
Temporary Copy Keys.
You can improve your copies by using the Temporary Copy Keys:
Enlarge/Reduce , Contrast , Quality , and Options . 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 document in the ADF within that time.
However, if you have set the Mode Timer for Copy and Scan modes
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 4-6.)
