Dear All Friend
I have a km-5050 with Job Accounting mode on. A few days ago machine gave C6000. I changed Fixing Unit with new one but i cant enter service mode because, when i power on, machine opens with Job Accounting/Enter ID-screen and after a few seconds give C6000 so i cant do U169. After C6000 screen i cant do anythink. any botton not works.
What is your opinion
