常见问题解答与故障排除

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.

When wireless network connection is unstable and the APIPA protocol is enabled, you might experience this difficulty.

Please follow these steps below to set the BOOT method back to AUTO and disable the APIPA protocol.
