Tips for using bar codes

Follow these tips to maximize the performance of the software:

Choose the pageA page is always in paper form and is part of a paper document. A page can produce one image (single-sided page), two images (double-sided page), or four images (both color and black and white) after scanning. setup name that you will use for scanning before you define a bar code zoneA bar code image that the software recognizes as a separator between batches or documents in images being scanned. Before a bar code image can be used as a separator, the user must define it as a bar code zone in the Capture tab of the Job Setup dialog box..
Make sure that all glass surfaces (the glass guides or glass over the camera area) within the scanner transport are clean. Dirty surfaces cause poor read rates.
Use a higher resolution to obtain better read rates (300 dpi vs. 200 dpi).
Check the positioning of the zone around the bar code; it can affect the confidence level of a bar code. Leave at least a ¼-inch of space around a bar code to guarantee that the full bar code will always fall within the zone. Move the zone around the bar code until the highest confidence rate is achieved.

Remember that the minimum bar code height specification is 40 pixels. At 200 dpi, 40 pixels is 20/100 inches; at 300 dpi, 40 pixels is 13/100 inches. For bar codes smaller than 40 pixels in height, specify a bar code height in the Bar Code Zone Setup dialog box.
Verify that the correct bar code type and bar code orientation are selected in the Bar Code Zone Setup dialog box.
If bar codes are on documents with color backgrounds, you may need to lower the threshold value in the Bar Code Zone Setup dialog box for improved read rates.
If possible, use bar codes that have a density of medium or lower. Bar codes of high density may require lowering the threshold value in the Bar Code Zone Setup dialog box to read the bar code.
Lower the quality level in the Bar Code Zone Setup dialog box as necessary to achieve better read rates on more difficult bar codes.
When using Anywhere bar code zones, use a PC with a 2.0 GHz processor or higher. This will ensure the software’s ability to scan at scanner rated speeds when bar code reading is enabled in the application.
