If You Print Regularly on Photo Paper as well as on Plain Paper
If you use photo paper as much as plain paper, you can load photo paper in the Rear Tray and
plain paper in the Cassette. This way, you can switch the paper source according to the type of
paper just by pressing the Feed Switch.
You can also specify the type and size of paper to be fed from the Cassette using the printer
driver. You can print more efficiently by specifying the type of paper you use regularly this way,
since the paper source will be switched automatically to the Cassette for this paper.
(A) Rear Tray: Load paper of various types and sizes, including photo paper
(B) Cassette: Load paper you use most regularly, such as plain paper
If You Print Mainly on Plain Paper
You can load plain paper of the same size in both paper sources, and set the printer driver to
automatically switch the paper source when either paper source runs out of paper during
printing.
(A) Rear Tray: Load plain paper
(B) Cassette: Load plain paper
