I have an Epson Expression 1640 XL, connected by USB cable to my Windows XP Professional system, which is running the software that came with the scanner. It used to be that when I did a high resolution scan, after the actual scanning was finished, it would take about half as long again to finish sending the data to the PC. Then I found, more and more, that after the scanning was finished it would take five or more times as long again to finish sending the data. Nowadays I almost always have this long wait. I want to get back to the relatively fast data transmission that I once had. I have tried uninstalling the software, downloading the latest version from the Epson web site, and installing it. I have tried uninstalling this latest version and reinstalling the version that came on the CD with the scanner. I have tried closing Windows, restarting it, and launching nothing but the scanner software. I have tried replacing the USB cable by a new one. None of this helps. Can anyone suggest a way of getting the data transmission to work faster? I find that while the actual scanning is happening, my PC's CPUs are largely idle, but during the long pause one of them is fully occupied running Eccndv.exe. Nick
