Hi, I scan documents (recto and recto-verso) using the InformatikScan software and the scanner Canon DR-9080C. When I scan for ex. 30 pages, after 10 pages the scanning process slows down in performance. InformatikScan proposed me to do the following 2 things : - disable "Scan ahead" - Update the Twain drivers and the InformaikScan soft to the latest version. But how do I change the "Scan ahead" parameter of the Canon scanner ? Regards, Johan

As with most people who have no idea what they are saying like talking about disk fragmention when this doesn't exist in Windows for years now as the task manager automatically defrags. I'm afraid this problem seems comon to all scanners and I doubt anything can be done other than scanning a few pages at a time and waiting.

The scanner creates a Raster Image and if it is grey or color, the size is big. After a few images are scanned, the 'buffer' inside the scanner is full. It may take more time to process the scanned image by the scanner if it is 24 bit color. The image is sent to the computer Harddisk and if the disk is full or if it had not been defragged for a long time, the sectors may not be contiguous for speedy writing, This will slow up the scanning. Ensure the disk has large space. 'Scan ahead' slows down scanning speed. (Without scan ahead, the next page is fed only after processing, whereas when selected, just after the previous page is scanned, the scanner start the next one)
