Creating Patch Code Sheets
Make copies of the patch code patterns provided at the rear of this manual. Follow the guidelines below when
copying patch code patterns.
● Copy the patch code patterns onto paper of the same type as that of the document to be scanned. If the paper
thickness substantially differs, a feed error may occur.
● Copy patch code patterns ensuring that the copies maintain the same size and image density as that of the
document. If the copies are too light or dark, they may not be scanned properly.
● Copy patch code patterns so that they are positioned on the page within the detectable area specified below.
Units: inches (units in parentheses are millimeters)
0.2" (5 mm)

Patch Code
(Range in which patch code
detection is enabled.)
● Take care not to get patch code sheets dirty, especially within the detectable area. In order for the sheets to be
scanned properly, make sure they do not get folded or crumpled.
● If the image density is too light or dark, the patch code sheets may not be scanned properly.
