I recently spent time working on a 307ci that had the 3 colors washed out, but black was fine. The U410 shows from a good 308ci & the problem 307ci. After trying U021, HV PWB & Primary belt, I ended up finding that the transfer belt release motor housing was cracked. We had one in stock as I've replaced a couple in the past that generated errors when the shaft in it broke. This machine didn't have an error code. I pulled apart 4 different machines in our warehouse & all 4 had that housing cracked. I know one of them had light yellow prints that we never could remedy and ended up replacing with a 308ci.
I'd say if you're having any color issues on these series of machines, that would be a good place to start. I doubt at this stage in the lineup that the part will get updated, and 40 & 50 uses the same part.
