“Troubleshooting,” in the Advanced Guide.
Q Is the Error indicator blinking?
A If the Error indicator is blinking, see Chapter 7,
“Troubleshooting,” in the Advanced Guide.

glass or in the ADF correctly. (See Chapter 2,
“Document Handling,” in the Basic Guide.)
Q Is your computer working properly?
A Restart your computer.
Q Is a USB hub or repeater working properly?
A When using a USB hub or repeater, try connecting
a USB cable directly to the computer to check if it
works properly. If you can scan the document
successfully after connecting a USB cable directly
to the computer, check your USB hub or repeater if
it is working properly.
Q Are you using a USB 2.0-compatible USB hub?
A If you connect the machine to a USB 2.0-equipped
computer using a USB 2.0-compatible USB hub,
you may not be able to scan. In this case, connect
a USB cable directly to the computer.
