Patch description
This document provides information that supports the following scanners.
• Kodak Scanners 9XYZ, 5XYZ, 7XYZ, i800/i1800 (with image addressing) Series Scanners and the
Kodak Microimager 70—these scanners are equipped with the Patch Reader. The Patch Reader recognizes
patches with bars that are parallel to the lead edge of the document. All of these scanners may use patches
for image addressing. In addition, the i800/i1800 (with image addressing) Series Scanners may use toggle
patches for Color on the Fly functionality.
• Kodak Scanners i280, 3590C and i600/i1800 (without image addressing) Series Scanners—these
scanners are not equipped with a Patch Reader. These scanners recognize patches with bars that are per-
pendicular to the lead edge of the document. These scanners will only recognize the toggle patch for Color on
the Fly functionality and do not have image addressing.
A patch is a pattern of parallel, alternating black bars and spaces that is printed on a document.
Kodak Scanners which have patch reading capability can recognize patch documents
and automatically assign a document image level, increment the document image address, or perform Color on
the Fly functionality.
The wide bars should be 0.20 inches (5 mm) wide
+ 0.01 inches (0.25 mm). The narrow bars and spaces should
be 0.08 inches (2.03 mm) wide
+ 0.01 inches (0.25 mm). The maximum width of the patch code is 0.80 inches
(20 mm)
+0.01 inches (0.25 mm). The minimum overall length of the patch bars is 2 inches (50 mm).
NOTE: The patch codes illustrated below are not to spec. Use the patch sheets included in this packet for
specifications.
