You could remove the laser and thoroughly clean it and Check all the laser unit connectors and reseat them. But an SC220 code is normally a bad LSU. Replacing LSU or just the parts inside the Laser unit will probably be the fix for you.

Laser unit----D019 1900
Polygon mirror motor-----B209 1898
Laser Diode Unit-----D019 1919


I normally find that just replacing the Polygon mirror motor usually resolves the issue but sometimes you need the Laser diode unit.

If you actually toke the top off the laser unit and cleaned inside it, you might have knocked a lens out of position.

Check if you might accidentally reversed the lens in the LD unit.
The trick is to touch the surface of the lens and which ever has the image flushed against it is the correct side.
