Re: Bizhub C550 no response

Sounds like a bad stick of RAM. Try switching the 2 sticks around. If the machine doesn't boot at all after that, then you have confirmed that one of the sticks are bad. Then the fun of trying to figure out which one it is, or just replace both.

I'd still give the RAM swap a try, but that error points to an issue with the MFP board. Re-seat the connections of all wires, etc. And see what happens.

I'm assuming all imaging units are in the copier? If so, I'm going to say that either one is not in all the way, or the contacts are dirty. Pull them out, clean up the contacts both on the image unit and inside the copier and see if that clears up that message. That would be the easiest potential fix anyway.

Yes all imaging units are in the copier. a cleaned up contacts- no result

Re: Bizhub C550 no response

That code means the cyan TCR sensor adjustment failure. You can try cleaning the sensor if that doesn't work you'll have to replace the cyan imaging unit.
