Scanning Is Slow; Solving Scanned Image Quality Problems - Epson FF-640 User Manual

Scanning is Slow

If scanning becomes slow, try these solutions:
• Scan your original at a lower resolution, if possible.
• Make sure your system meets the requirements for your operating system. If you are scanning a high-
resolution image, you may need more than the minimum requirements. If necessary, increase your
system's memory.
• If you are running virus protection or other security software, exclude the TWAIN.log files from
monitoring or set the TWAIN.log file as read only. See your virus protection or security software
instructions for details. The TWAIN.log file is saved in the following locations:
• Windows XP: C:\Documents and Settings\(user name)\Local Settings\Temp
• Windows (other versions): C:\Users\(user name)\AppData\Local\Temp
