IMPORTANT
• When you copy the originals, adjust the size and density settings to match
the originals. Extremely dark or light copies may not scan correctly.
• When you copy the originals, adjust them so that the patch code pattern is in
the effective area for detecting patch code patterns.
• Make sure that the originals are not stained or marked in any way. Take
special care to avoid staining or marking the effective area for detecting
patch code patterns. Also, take care to avoid bending or wrinkling the patch
code sheets. Damaged or marked patch code sheets cannot be read
correctly.
• To avoid a reading error, make sure that the scanning density for patch code
sheets is neither too light nor too dark.
