I have an HP Color Laser Jet 2840. When I clicked on the &quot;Scan Document&quot; in the HP Director window I got the error, &quot;An error occurred communicating with the scanning device....&quot;.Also, got this message in Firefox, &quot;Firefox can't establish a connection to the server at 127.0.0.1:5225.&quot; <br />
<br />
I can still print to the printer but cannot not scan from this 3 in 1 device. Any ideas on how best to troubleshoot?
