Chapter 4 Using the Scanner
◆ How to Use Patch Code Sheets

Print the patch code sheet on the following paper size:
● Print [PATCH II (A4)] and [PATCH T (A4)] on A4-size paper.
● Print [PATCH II (LTR)] and [PATCH T (LTR)] on letter size paper.
● Patch code patterns are detected within the enabled range shown below. When
you make a copy of the patch code sheet, adjust the position of the image so that
it appears in the range in which detection is enabled.
0.2" (5 mm)
3.7" (94 mm)
0.2" (5 mm)
0.2"

Patch code
(Range in which patch code
detection is enabled.)
Units: inches (units in parentheses are millimeters)
● When copying the patch code sheets, use the same size paper and the same
density as the original patch code sheet. If the copied sheet is not dense enough,
or if it is too dense, the scanner may not be able to recognize it correctly.
● Be careful not to let the patch code sheet get dirty, particularly for the range in
which patch code detection is enabled. Do not bend or wrinkle the patch code
sheet. This could prevent the scanner from recognizing the sheet.
● When the patch code sheet is being scanned, if it is not dense enough, or if it is
too dense, the scanner may not be able to recognize it correctly.
