Bar code and patch

code reading and

OCR indexing with

i200 Series Scanners

For all i200 Series Scanners, bar code and patch code reading and OCR

indexing is done using the bitonal front or rear images.

When dual stream scanning (e.g., scanning color and bitonal simultaneously)

with an i200 Series Scanner, the bitonal images are used for bar code and

patch code reading and OCR indexing. When a bar code/patch code/OCR text

is detected, all four images (Color front; Color rear; Bitonal front; Bitonal rear)

of the page are either deleted or attached to the new/current document or

batch according to your Bar Code/Patch Code/OCR Setup.

When color or grayscale scanning with an i200 Series Scanner, Capture

Software will still scan the bitonal images “behind the scenes” using the

grayed-out bitonal Page and Image setup settings (e.g., Bitonal resolution,

Contrast, Threshold).

While the “behind the scenes” bitonal images are never displayed or stored to

disk, they are used for bar code and patch code reading and OCR indexing.

Perform the following steps when setting up your color-only or grayscale-only

scanning application:

1. Enable the bitonal cameras in Page Setup and adjust the Page and Image

bitonal settings as necessary to achieve the best bar code/patch code

read rate or OCR results.

2. Scan some sample pages in dual stream (e.g., color and bitonal

simultaneously) to make sure that bar code/patch code/OCR reading

works correctly.

3. Go back into Page Setup.

4. Disable the bitonal cameras for production color-only scanning.

NOTE: When scanning a sample image in Bar Code/OCR Setup for the

purposes of defining bar code/OCR zones, Capture Software will

always scan and display the front bitonal image.
