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 or reduce the resolution.
Make sure you did not press the slow mode button to slow down
the scanning speed (DS-C490).
The scanning speed may be reduced depending on the image
adjustment features in Epson Scan 2.
If scanning
becomes slower after scanning continuously with the ADF for a long
time, the scanner may have automatically slowed down to protect the
scanner mechanism from overheating or becoming damaged. Let the
scanner rest with the power on for 30 minutes, then try scanning
again.
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 C:\Users\(user
name)\AppData\Local\Temp.
Note: You may need
to unhide system folders to view files in that location.
Computers with USB 3.0 (SuperSpeed) or USB 2.0 (Hi-Speed) ports
can scan faster than those with USB 1.1 ports. If you are using a
USB 3.0 or 2.0 port with the scanner, make sure it meets the system
requirements.
