Patch function overview The Patch Readers Patch types Patch 1 All i1800 Series Scanners provide toggle patch capability. This type of patch is used to trigger the scanner to switch from the current image stream (black-and-white) to the alternative image stream (color/ grayscale). Patches used for image address level changes are only valid when using an i1860 Scanner with image address enabled. The Patch Readers allow you to automatically increment the image address or initiate a special function. Image addressing must be enabled in order to use the Patch Readers. Patch sheets are inserted during document preparation. For i1860 Scanner only: There are four off-center, permanently mounted Patch Readers. They can be independently enabled or disabled by your capture software application. If more than one Patch Reader is enabled and any one of the enabled Patch Readers successfully decodes the patch, then the patch will be read. Also, if the patch bars pass under more than one patch head that is enabled, there is a higher probability that the patch will be read. NOTE: Almost all patch reading problems are related to poor quality patch codes or patch sheets. Using only the best quality printed patch sheets will ensure the highest possible read rates. See Kodak publication A-61599, Patch Code Information, for complete information. Patch Types 1, 4, and 6 - these patch types can be used by the capture software application to perform post-scan functions. These patches are not used for image addressing. IMPORTANT: Do not use these illustrated patches for production - they are not to spec. Patch 4 Patch 6 Toggle Patch - the Toggle patch is a Type 4 patch that is used to trigger the scanner to switch from the current image stream (black-andwhite) to the alternative image stream (color/grayscale). NOTE: Toggle patch orientation is different depending on whether image addressing is disabled or enabled. 4-12 A-61555 March 2007
