Solution
1. Display the Printer Status Window.
2. From the [Options] menu, select [Device Settings] > [Cassette Settings].
3. Select the size of the paper loaded in the paper cassette (1), then click [OK] (2).
NOTE
If you want to change the size of the paper loaded in the paper cassette frequently, it is convenient if you specify [Free Size].
If [Free Size] is specified, you do not have to change the setting each time the different size paper is loaded.
If [Free Size] is specified, however, make sure that the size of the paper loaded in the paper cassette always matches the size selected for [Output Size] in the [Page Setup] sheet before printing.
