A bad barcode error message is displayed when the Strict Barcode check box has been selected. This checkbox is found on the Check In screen, Item Status screen , and In House Circulation screen.

When this checkbox is selected, Evergreen  expects only 14 digit Codabar barcodes and alerts you every time a different format is scanned. Un-check the Strict Barcode box on affected screens on affected computers to resolve the error.
