C8000 Stuck on warming up.

[Rhoadster67]

I have C8000 that stays on warming up. Wont code out. no service codes in log in service mode. removed fuser and tested in demo unit, works fine. thermistors in i/o mode show temperature coming up. fuser continues to cycle, rotation, lamps cycle on and off. replaced conveyance control brd and print control brd. any ideas? going to look at wire harnesses.

First step is to reload all firmware....

Did you get it repaired . Which controller have you

Ok, after going over harnesses, both fusers with no change. I started looking at accessories. wound up being the SD-506, saddle stitcher. M11 on the slope section. during its startup the motor would turn and hang. It could not finish its initialization. the main body just sat there waiting on it and never coming out of warm up. I cant believe it never coded out. just remember that warming up doesn't always mean fuser.

Had same issue just now, checked power to SD506, A/C plug seemed loose and it is in a hallway between 2 machines so easily knocked out. After pushing in the plug and open/close of SD506 it came ready. Thanks a bunch!
