This is a patch for the issue of the media feeding.

To apply, decompress the attached file and place the extracted file in the following path: C:\Programs Files\SAi\SAi Production Suite\OutputDrivers.
After you placed the file, open Production manager, delete the current DC4 setup and re add a new one for the Summa DC4 so the new DLL will take effect.
Note - This worked for my DC4sx as well, both printers seem to use the same driver file.
Special Thanks to Matt from Jayhawksigns
