"
When printing on postcards,
make sure that the output bin
is horizontal.
If the output bin is slanted
while printing, the postcards
may be curled and an error
message may appear before
the output bin contains 10
sheets.
In addition, the output bin extension
can be pulled out to two different
positions.
Use the appropriate position
depending on the size of the media
being printed on.
