Only the paper trays specified to [Do not Display] or [Recycled Paper] in [Paper Type] and also specified to [Yes] in [Apply Auto Paper Select] under [Tray Paper Settings] can be selected in Auto Paper Select mode. Trays with a lock mark (
) will not be automatically selected. For details, see "Tray Paper Settings", Connecting the Machine/ System Settings.
If no paper suitable for the size and reduce/enlarge ratio you have specified is loaded in the paper trays, load paper of the required size in a paper tray. Alternatively, you can select a suitable reduce/enlarge ratio for the paper currently loaded in the paper trays. After doing one of the above, place your original again.
