• Do not place objects that weigh 4.4 lbs (2.0 kg) or more on the platen. In addition, do not press on
the item with a force exceeding 4.4 lbs (2.0 kg). If you press heavily, the scanner may not work
correctly or you might break the glass.
• Align the item with the edge of the platen. If placed slanted, correction will not be applied properly.
• Correction may not be applied properly depending on the item. If the page background is not white,
shadows may not be detected correctly or may not be detected at all.
• While scanning, press down on the spine with the same amount of pressure you used to preview
the scan. If the binding part is not even, correction will not be applied properly.
