does the machine have a fax? if yes than receiving a fax the data light will flash
how about sending a job to user box the light will also flash or a private print job.

make a capture with wireshark , we see that more on the NEC machine one of the pc,s starts sending data over TCP\IP to the NEC machine and this machine is showing that with blinking. the machine is sensetive for this. make then a ip filtering for that machine
