Are the sensors (front and rear) that read the color registration clean? Did you try to perform the Color Registration / Manual from Service Mode?

I had the same problem with KM C550 and what I did was that I adjust the skew laser.
Just reset and start changing values of the yellow and it will help.

There are several differences between C500 and C550, the first is a Printing Production equipment, the second is just a high volume office equipment.

Try to perform the Manual Color Registration first, then the Automatic after that. You might need to try the Manual adjustment several times before succeeding with the Automatic. Also, how did you clean the sensors? If you cleaned them with a dry cloth, they might still be dirty, as warm toner tend to stick quite strongly to the sensor's window. Use a moist cloth and then a dry cloth afterwards.

I've completely removed color registration unit and clean everything in it. I don't know how to do the manual adjustment, i've made only automatic colour registration.
