Changing the Size of the Paper in the Paper Tray
To load longer sizes of paper, such as Legal-sized paper, you
need to adjust the paper guides to extend the paper tray.
1 After pressing and unlatching the guide lock, slide the paper
length guide out completely to extend the paper tray to its
full length.
2 After inserting paper into the tray, squeeze the length guide
and slide it until it lightly touches the end of the paper
stack.
For paper smaller than Letter size, adjust the front paper
length guide so that it lightly touches the paper stack.
