Read the following instructions before placing originals.
When placing bulky originals such as books, prevent exterior light from shining directly onto the scanner glass.
If there is any trash or dirt on the scanner glass, the scanning range may expand to include it, so the image of the original may be displaced or reduced.
Do not apply too much force to the scanner glass or the document cover. Otherwise, they may be damaged.
Remove the originals after scanning. If you leave the originals on the scanner glass for a long time, they may stick to the surface of the glass.
