If you are using a Kofax card (and any scanner), this flag specifies the extent to which buffering is used. Normally you should choose 3 pages for maximum performance. Increasing the value above 3 may result in faster scanning, but the disadvantage is reduced control during the scanning process.
If you are using an ISIS interface, this flag specifies if ScanAhead is to be used. (See INVOICES Help topic ScanAhead for information.)
This flag can be set in the ISIS scanner settings or Kofax scanner settings dialog.
0 or any positive integer
Value if missing: 3
