Set the [Output Size] setting to the size of the paper loaded in
the printer as needed.
Leave the setting set to [Match Page Size] when the page size and the size of
the paper loaded in the multi-purpose tray are the same, since there is no need
to change the setting.
IMPORTANT
If the [Page Size] and [Output Size] settings are different, the printer produces an
enlarged or reduced print automatically.
