There are four different paper supply indicators, as shown below:
2
■ Auto Orientation
Using information, such as the size of the original and zoom ratio, the machine
automatically rotates the image to the most suitable orientation for the selected paper
size.
If the image does not fit onto the paper after it is rotated, the machine will not rotate the
image, and will print it as is, with part of the image cut off.
Even if Auto Orientation is set to 'On', the image is not rotated if the Different Size
Originals, Cover/Sheet Insertion, Staple (Double), Transparency Interleaving, Framing,
XY Zoom, Shift, or Image Repeat mode is set, or a nonstandard paper size is specified.
(See Chapter 8, "Customizing Settings," in the Copying and Mail Box Guide.)
