Some scanners, such as the Fujitsu fi-5900C, require the endorser to be a certain length. If your scanner has this limitation, use the EndorserIndexLength setting in Eiglogal.ini to specify the length of the endorser.
Note: When using Virtual ReScan (VRS), the Fujitsu fi-5900C has problems printing times and dates, using %T and %Y, as specified in the scanner's documentation.
