Can't get imageClass D550 setup to scan

I just purchased a new imageClass D550.  When attempting to use it as a scanner, after I navigate to SCAN > Computer, I get a message that reads, "Connect to computer."  Then nothing else and I'm not able to scan or pull up the properties menu as seen in the manual.  The printer and copier work fine, so I know that the machines are communicating.  Can you tell me what I might need to do to fix this?  Is there a separate driver for the scanner?  (When I installed the software, I did opt for the scanner to be installed also).  Any insight is appreciated.
