So I've not seen this code before. Looking up the error, looks to be a Auto-Toner sensor (C) code. I had no idea where that was, so I looked up it's location in the service manual. It appears to be on the Dev unit, is that correct? If so, does anyone have any experience with testing it, replacing it, or them going bad in general? If so, what are some other things that I can check on which would cause this error. Thanks.

So the coverage on the mag roller was perfect, but I noticed that the lower gears were locked up. Manually rotated them for a couple minutes, and they freed up. Printing color as it should now. -
