FAQs & Troubleshooting

I configured the "IP Config" method of the machine to "Auto" to assign an IP address automatically, however it was changed to "Static" unexpectedly. I get an error message that indicates IP address is not unique, or a document is printed out by the machine I didn't expected. What can I do?
