Not enough memory to execute scanner settings
ScanFront uses internal memory to scan documents. This memory usage increases when you use high-resolution or large page size 
settings, for example. If the internal memory capacity exceeded, an error message saying “Not enough memory to execute current 
scanner settings” may appear and you may not be able to scan the document.
The following table details scanning conditions that may cause ScanFront to run out of memory. If scanning cannot be executed 
due to insufficient memory, refer to this table to reset scanning conditions.
