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, 
follow this procedure below to modify the INI file. It is recommended that before 
opening the file in step 1 below, you make a backup copy of the file in another
