Bar code and patch
code reading and
OCR indexing with
i200 Series Scanners
7-4
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.
