Konica magicolor 2430DL network dhcp doesn't pick up right address

I have a 2430DL for 7 years, used to change the IP address of the printer in my XP settings when printer or router was reset. Now I bought a 2nd hand 2430DL because my 2430DL got a fuser error which I couldn't resolve (till today) . This 2nd printer was on DHCP and had IP address 169.254.66.200 (assigned by former owner I think) with subnet mask 255.255.0.0 and for the gateway all zero's. Afaik strange combination. Now I disabled DHCP on the printer (DHCP and BOOTP off) and gave it the for my situation normal and usable address of 192.168.2.8 sm: 255.255.255.0 and the only correct gateway: 192.168.2.1 . No joy and as from start the usually green light near the network cable was irragularly blinking orange. I also assigned the printers mac address in the router with port 192 168.2.8 without result. Printer remained absent in the network .. Printer back to DHCP and again a strange IP address with two zero's subnet mask and zero's for the gateway showed up. I also reset according the printer menu to default settings... and again no result... The ip address might be picked up from somewhere else if it was a wireless connections, but it's wired. Maybe it's a fault in the printer program ? in the network hardware part ? Kind regards from the Netherlands...
