Xerox 700i Digital Press Color Network Scanning Problem

Our iMac is connected to our Xerox 700i Digital Press Color printer/scanner through an IP address that lets us scan images from the printer to the computer. Just recently we recieve this error every time we try to go to our printer's IP address:

Service Temporarily Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

The Safari tab reads "503 Service Temporarily Unavailable."

Please, if anyone can help us get our network scanning up and running it would really help.

Thank you :]
