• Make sure your system meets the requirements for your operating system. If you are scanning a highresolution image, you may need more than the minimum requirements. If necessary, increase your system's memory. • 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. • Make sure Slow is set to Off on the scanner control panel. • If you are scanning over a network, factors such as interference, network traffic, or weak signal strength may affect your scanning speed.

Cannot Scan Over a Network
If you cannot start Epson Scan 2 when scanning over a network, try these solutions:
• Restart the scanner and check the IP address on the scanner control panel.
• Make sure the Ethernet hub is turned on.
• Restart the Ethernet hub, wait for approximately one minute after restarting, then check the
connection again.
• The order in which the Ethernet hub and scanner are turned on may cause a temporary connection
error. Restart the scanner, wait for approximately one minute after restarting, then check the
connection again.
• If network communication was interrupted while starting Epson Scan 2, exit Epson Scan 2, wait a few
seconds, and restart it. If Epson Scan 2 cannot restart, turn off your scanner, turn it back on, and try
starting Epson Scan 2 again.
• Check the network connection setting in the Epson Scan 2 Utility.
• Make sure the Ethernet cable is connected securely. If the connection status light on the Ethernet hub
is off, check the light status by connecting the Ethernet cable to another port or changing the Ethernet
cable. If this does not solve the problem, replace the Ethernet hub.
• If you see a message telling you the product is not available, there may be a communication error
between the scanner and computer. Restart the scanner.
