If your scanning speed is lower than expected:
The most common contributor to slow scanning speed is the specification of the host PC. In particular, please check the following:
As a general rule a faster CPU (Dual, Quad or Hex) and a larger RAM is better.
Scanning directly to a storage location that is not on the host PC (e.g. a shared network drive) will have a huge impact on scanning speed. We do not recommend you attempt this.
Some Anti-Virus packages may be set or configured by default to attempt to scan files that are created on the host PC and can cause the scanning process to slow down. If your Anti-Virus package is doing this we recommend that you exclude the folder to which your scanned images are being written.
Another common contributor is settings being used in the application or driver. For example, in the Fujitsu TWAIN Driver:
Note: same or similar functions can be found in the ISIS driver if your application uses ISIS instead of TWAIN.
Scanning with all image processing functions enabled requires more post image processing and can slow down the scanning speed, especially if the host PC is not of a high specification. It is therefore recommended to disable functions that are not required for your document types.
