It's hard to help when the model is not even mentioned.
I can assume it is a C65xx or C55xx machine.
Appears to be a blown ICP on the printer control board. the Solenoids are not energising in the colour reg unit.
Most likely causes are the wiring going to the total mechanical counters have been pinched and are earthing to the frame or the wiring to the belt claw solenoid is earthing to the frame.
Best way to confirm is tape open the shutters on the colour reg unit and see if it will complete an Auto Gamma and Auto Colour Registration. If it completes then you have a blown ICP.

Re: Error Code: 4520-2851

Have you taped the shutters open and tried auto gamma and auto color reg?
Have you tried to output any test patterns to see if you have an issue with one of the colors?
try outputting test pattern 81 with color densities all at 255
