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 are connecting a USB 2.0-equipped computer and the printer 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.
If you want to connect the printer and computer via a USB 2.0-compatible hub,
