OK first verify that you can print to the printer side of the KM-5035 if you can you are good for the printer. Next try to ping the IP address of the scanner in the KM-5035. If you get no response than your PC is not communicating with that component. Also verify in the Network Scanner setup that your PC IP is one of the IPs it can scan to. If it is not there then this is your problem. Your IP must be one of the IPs it can scan to. Try this and see what happens.
