Explanation:

The device dropping off the network, or losing network connectivity, in certain customer environments is caused by the printer renegotiating its IP address when entering or exiting sleep mode. This speed renegotiation is necessary for Blue Angel compliance. Please be aware that disabling ethernet renegotiation will take the device out of Blue Angel compliance.
