Open the input tray and extend the input tray extension. Slide out the output tray, extend the output tray extension, and then raise the stopper.
If there are any thick originals amongst the originals, to stop the thick originals from bumping into the output tray and falling out, store the output tray and do not use it to stack the ejected originals.

Slide the edge guides on the input tray all the way out.

Load the originals at the center of the input tray in descending order of paper size with the widest at the back and the narrowest at the front.

Load the originals into the input tray facing down and slightly displace the top edges at an angle facing into the ADF.
Slide the originals into the ADF until they meet resistance.
You can stack the originals up to 8 mm (0.31 in.).
Slide the edge guides to fit the edges of the widest original.
