Using the Patch Code Properties Dialog Box

Use the following options to enable patch code detection.

Enable

Select the Enable check box to take advantage of the patch code detection feature.

Left Offset to Center of Patch Code

The Left Offset to Center of Patch Code is a value you select from the left edge of the

page to define a point near the center of the patch code. The offset value allows the

patch code detection feature to quickly locate the patch code on the page. This offset

can be any value in inches between 0 and the maximum page width. A value of 0

specifies searching anywhere in the horizontal direction for a patch code.

All patch codes are made up of narrow and wide bars as follows:

 The narrow bars must be 0.08 inch in height.

 The wide bars must be 0.20 inch in height.

 The entire patch code must be 0.80 inch in height.

 The entire patch code should be at least 2.0 inches in width.

To be detected, patch codes must be positioned correctly on the page:

 The patch code must be horizontal.

 It must be located at least 0.20 inches from the leading edge of the image.

 It must not extend beyond 3.75 inches from the leading edge of the image.

In compliance with the patch code specification for duplex scanning operations, patch

codes are only detected on the front side of a page. Patch codes on the back side of a

page are ignored.

Note As an alternative to using patch codes, you can specify that a bar code be

interpreted as a patch code, as well as a bar code. This might be useful, for example, if

there is always a bar code on the first page of each document. The Bar Code Properties

dialog box is used to configure bar codes for use as patch codes. For more

information, refer to Using the Bar Code Properties Dialog Box on page 140.
