OUr bizhub pro 1200 keeps coding out with code C-3906. We found the tech suggestion that says to take the back fan covers off and it should be fine. We tried running 11x17 (the tech article said it happens with bigger size sheet like 12x18) and it happened again. We powered down and powered up and it wa clear so I tried running 24# 8.5x11 and after 241 sheets it coded out again. We took the fuser out and it is the hottest we have ever seen a fuser with no physical signs of damage. Has anyone else ran into this problem before, if so what was your solution? Any ideas as to what you think it may be are welcome. Thank you in advance.
