MP C2800 533 error

[gkalman2004]

Hi everybody.

I have more MP C2800 machines in service but for me is the first time when i receive this error..
SC533 error but this machine does not have IH inverter coil and fan as far as I know.
Tomorow i will check the fans but i ask anywhay
In my case can be the paper exit fan or the machine still has IH inverter fan?

I already read the error code from the manual but i don't find in the parts catalog, and i don't remember about this fan on this machine.
Yes on MP C4000 i have IH coil and fan and inverter board ( is under the front/right part cover)
but i don't remember to be one on the MP C2800 also i don't find it in the part catalog.

Today i open the machine and i take out every fan for testing and all was ok.. machine dead.
I check all fuse and was ok .. machine dead

Finally i change the IOB and this time the machine start up without error.
And no i don't find any ih converter allmost all fan cables go to the IOB just for the hdd the cable come from the FCU
So i learn something new
when you have SC533 for MPC2800 is the IOB controller
When you have SC204 but the display work the right door ground cable is cutted.
When you have SC202-204 without working display you must replace R294 from the bicu
For IOB you must replace R59
