hi, i have printer samsung 4070fr, worked well but have problem in lan port
its stop works after short time. and need to play with cable a lot to make connection.
the port pins is OK. the all main board checked in lab and its good.
I don't know what the problem is
have one solution for temporary repair (some hours / days / week..) using contact cleaner spray. short spray and its work
but I am need to turn the printer every time to get access for the port so its not the best solution
what I can try?
