Document scanning via the Dynamic Web TWAIN SDK is slower than using the native scanner application. How can I speed it up?
Please first check if you use the same pre-scanning settings (e.g. color mode, resolution, etc.).
Assuming the pre-scanning settings are the same, please double check if there are any automatic actions after scanning pages. You may double check the call back functions of the AcquireImage function or check if you write any code in the OnPostTransfer or OnPostAllTransfers event. If you need to run some automatic actions right after each page is scanned, it’s recommendeded to use the OnPostTransferAsync event.
If the scanning performance issue persists, please contact us.
