I am an ex copier tech. I am having trouble remembering the correct sequence for accessing service mode. I think it's c i o i for the 2040 but I just can't remember...I know the reset is #14. Sometimes thermistors "glitch" when they are getting old and you can reset them and it will work ok for a little while.Thanks Guru,

You have a fuser code caused by the machine not warming properly.
Before you call someone try this.
Press P * C * or # * C * on the machine consol. Then enter the number 14 as if making 14 copies. Then follow what it tells you to do. Some you just press the start button to clear it, some you press 1 then press start.
There are several solutions to this problem:
1. Adjust the exposure
2. The drum may be out.
3. The developer may be out.
4. Finally, You may need a PM for the copier. (replace the drum, developer, drum blade)
