This settings controls the sensitivity of the scanner’s "detect double-feed" function for Panasonic scanners such as models 905C, 2025 and 2045, and Fujitsu scanner model 4860C . It may work in different ways for different scanners, but 0 always results in the lowest sensitivity and 2 always results in the highest sensitivity, regardless of the scanner’s detection method.
For more information about this section of the Scanner settings dialog, refer to Advanced scanner settings: ISIS settings (INVOICES Help topic).
0 (low double feed detection sensitivity)
1 (normal double feed detection sensitivity – default)
2 (high double feed detection sensitivity)
Important: When DFSensitivity = 1 (normal), the Double feed detect setting in the Advanced section of the Scanner settings dialog must be enabled.
