● Even if the barcode base color and the barcode color are colors other than white and black,
the barcode may be able to be recognized. To recognize colored barcodes, adjust the color
document scanning settings to ensure that the documents are recognized correctly before
using the barcodes.
● Barcode recognition results may include errors if a barcode is smaller than the minimum size
required.
● If barcodes that meet the conditions are not being scanned properly, performance may be
improved by trying the following.
- Specify a higher resolution in the scan settings
- Scan colored (gray) barcodes in "Black & White" and monochrome barcodes in "Color"
- Print barcodes with a higher resolution (at a higher quality)
- Increase the size of the barcodes
- Reduce image noise by lowering the scanning compression rate
- Change the paper that barcodes are printed on to paper with a higher level of whiteness
● To carry out check digit verification on a barcode type where the check digit is unchecked,
calculate the check digit and verify it yourself.
● When using a barcode type where the check digit is checked, the barcode value will not be
output if the check digit verification indicates an error. If barcodes are not being recognized,
check that the check digit is correct.
