Can your computer use a 
USB connection?

Check your computer whether or not 
a USB interface can be used on the 
Device Manager in your computer.
(For information on "Device 
Manager", see Help in Windows.)
If USB can be used, your controller 
chipset type and root hub will appear 
in "Universal Serial Bus controllers" in 
"Device Manager". (The items that 
appear will vary depending on your 
computer.)

If these two items appear, USB 
should be useable. If a yellow 
exclamation point appears next to 
"Universal Serial Bus controllers" or 
the two items do not appear, refer to 
your computer manual or check with 
the manufacturer of your computer to 
enable USB and then reinstall the 
printer driver.

Check the details below and reinstall 
the MFP driver correctly.
If the machine was connected to your 
computer with a USB cable when the 
MFP driver was installed, check if 
information on the unsuccessful 
installation remains in "Device 
Manager". (For information on "Device 
Manager", see Help in Windows.)
If the model name of the machine 
appears in "Other devices" in "Device 
Manager", delete it, restart your 
computer, and install the MFP driver 
again.
