As the title suggested, I'm using a Lexmark Optra T614 as a network printer, connected through rj45 cable. Printer is configured to use DHCP, on which I made a reservation.
Be aware : Everything works fine when printer has just been powered up, it does contact the dhcp server and pickup it's ip adress. But after a while, the printer's connection is lost... I can't ping the printer anymore and, of course, no print job can't be sent to the printer!
A power cycle solves the proble (Turning printer off then on again) for another couple of minutes / hours
Problem is not constent, and does not look like it's comming from the power saving utility...
Help! Steph
