FYI, there is bulletin for F56-11 at power up. CN80 is not "fully" connected, sheet bypass connector.

Let the machine warm up and code or go into 47 mode and turn each on for a second.
Take each corona unit out and check the wire then smell the end blocks.
Ozone is a very strong smell.
Where you smell it there is the arc.

Tranfer and Seperation Unit

I checked the sheet bypass connector CN80 (removed and reconnected) still the same error.
I was about to check the corona in the 47Mode, but wanted to see the parts before.
After taking out the T/S unit, I realized the separation wire is broken!!
I don't remember seeing that the first time taking it out.

Could that be caused by the arcing? and is it recommended to replace both wire (separation and transfer) together and maybe as well the charging wire?

Thanks again for any help you can provide

HAHAHA! Yes the snapped wires are the problem.
You need these, this is how your copier works

u should do both wires together. but u do not need to change the charge unless you see an issue with them.

I ordered the 2 wire and will replace it.

Another stupid question: why does arcing occur and how to I prevent it from happening again with the new wire?

[pepper38_cnd]

Arcing occurs when humidity levels are high and the HV jumps to the nearest grounding point through the moisture in the air. If this happens across a plastic surface like the corona block the arc burns a carbon trail in the block, this trail become a conductive path and now shorts out the HV, causing a constant error (the block usually has to be replace or cleaned very well). Many manufactures have tried different methods of reducing arcing within corona blocks, the simplest is to fill the block with non-conductive grease ( although messy when it comes to changing wires ) this does work well in high humidity areas.

Corona Dope...

Search for it, great stuff. Cover the wires and your springs that hold transfer and seperation wires.
