By default the DICOM images DocScanFx creates are not compressed in order to be most compatible with storing to various PACS archives. On a slow network this can be problematic. You can extend the amount of time the application waits for a store event by increasing the DicomSendWaitTimeout setting. However, turning on compression of the images is a faster solution.
In version 3.1.0.4+, you can turn on image compression. To enable compression, in your MODE specific section or the COMMON section of your INI file set the CompressDicomFiles=True. If set to True the compression defaults to "JPEG Lossless, Non-hierarchical, 1st Order Prediction" - Transfer Syntax UID 1.2.840.10008.1.2.4.70.
Advanced Options: Custom arguments can be set with DcmtkDcmCjpegCommandLineArguments to adjust the compression type but if you do, similar arguments must be added to DcmtkStoreScuCommandLineArguments to specify the compression type that was used when the store attempt is made. If you need more information about these options please contact support.
