To scan a barcode (including a two-dimensional code), the barcode must meet specific conditions.
Refer to "Barcode Types and Detection Parameters" in the PaperStream Capture Help to confirm that the barcode you want to scan meets the conditions described therein.
Refer to "Barcode Types and Detection Parameters" in the PaperStream Capture Help to confirm that the barcode you want to scan meets the conditions described therein.
If a barcode that meets the conditions cannot be detected, the problem may be solved by trying the following solutions.
Solutions
- Specify a higher resolution for [Resolution] (*1).
- Change the setting for [Image Mode] from [Automatic Color Detection] to [Black & White] or [Black & White] to [Automatic Color Detection] depending on the current setting (*1).
- Increase the resolution of the printed barcode (increase the print quality of the barcode).
- Enlarge the size of the printed barcode,
- Set a lower compression rate for scanned images to reduce noise due to compression (*1).
- Turn off the Cleanup function (*1).
- Print the barcode on a paper with a higher degree of whiteness.
- When the image is color or grayscale, go to [Color Adjustment] and specify a higher value for [Contrast] to enhance the contrast in brightness (*1).
- When the image is color or grayscale, go to [Color Adjustment] and and specify a higher value for [Brightness] to reduce noise (uneven coloring) in white areas (*1).
*1: This setting can be configured in the scanner driver "PaperStream IP".
