I have a very strange problem with a Ricoh Mp 5002.
The machine has 465,000 copies.
I cleaned it because it was full of toner on all sides. I removed the fuser, the development unit, the transfer belt and the laser. The laser has the whole block, and the slide is cleaned by hand. After reassembling everything, and after having remounted the laser, I get a SC 220 error at startup. I checked all the wiring and everything is OK. I read that this error occurred to other users, how did you solve it? I also read that it can also depend on the front doors, but it's all closed.
Can someone help me?

Thanks so much
Could be something simple............Many SC 220 codes that appear after removing and cleaning the laser occur because the laser unit is just no longer seated properly.
