Dell 964 All In One Photo Printer Won't Scan

I have a Dell Dimension 3100/E310 desktop computer with a Dell 964 All In One Photo Printer.  I have Windows XP on it.

I had to re-install the Printer drives and software.  I can get documents to print fine.  I can get the printer to scan using the controls on the printer.  However, if I try to scan from the Dell 964 All In One Center on the computer, I get an error message that says

Scan Was Not Successful

Try these solutions:

* Make sure the All-In-One is powered on.  (IT IS.)

* Disconnect and Reconnect the USB cable.  (I DID THAT.)

* Disconnect and Reconnect the All-In-One's power cable.  (I DID THAT.)

* Restart the computer. (I DID THAT.)

Nothing worked.

Does anyone have any suggestions?

Thank you.
