Patch function overview

Patch function overview

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

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

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 1

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-and- white) to the alternative image stream (color/grayscale).

NOTE: Toggle patch orientation is different depending on whether image addressing is disabled or enabled.
