The following types of originals may not be successfully scanned using the ADF. If you cannot scan using the ADF, use the scanner glass.
Originals with an uneven surface such as letterhead paper
Originals with wrinkles or fold lines
Perforated originals
Original with labels or stickers
Carbonless papers
Curled originals
Coated paper
Carbonless paper contains chemical substances that may damage the rollers inside the scanner. If you scan carbonless paper, clean the ADF regularly.
Wrinkled originals may scan better if you smooth out the wrinkles before scanning.
To scan delicate originals or originals that are easily crinkled, use the scanner glass.
Labels or stickers must be firmly stuck to the originals with no glue protruding. When scanning an original with labels or stickers that look like they might come off easily, use the scanner glass.
Try to flatten curled originals before scanning.
