All black print is dim even after toner has been replaced.
Also getting a Color Regist Error. (This is an ongoing error before black print problem began)

You may have to replace the transfer belt or the drum. I would start with the drum first

I had this issue as well and changed the Black PCU and it fixed the problem.
