When the Cassette Feeding Unit-AF1 Is Attached
NOTE
At least one of the paper sources besides the multi-purpose tray must be set to 'On'.
The settings under [Copy] include an option called [Consider Paper Type], which determines whether the machine considers the paper type loaded in a paper source.
If you set [Consider Paper Type] to 'On', paper is not fed from another paper source when the original paper source runs out of paper, unless another paper source is loaded with the same paper size and type. For more information on stored paper types, see "Registering/Editing Custom Paper Types."
If you set [Consider Paper Type] to 'Off', paper is fed from another paper source when paper in the current paper source runs out, as long as the same paper size/type is loaded in that paper source.
5.
Press [OK].

NOTE
Paper sources set to 'On' are used for the following functions:
APS (Auto Paper Selection): The machine automatically selects the appropriate paper size (paper source) based on the original's size and copy ratio settings (when making a copy), or the set ratio of the image (when receiving a fax).
ADS (Auto Drawer Switching): If a paper source runs out of paper during a continuous print job, the machine automatically selects another paper source with the same paper size, and begins feeding paper from that paper source.
