Can be anything from the toner density sensor to PRCB....the one time I did have this issue is was the PRCB

this is a super common thing to happen to these machines and yet to be found fixes. There is a lot.

Clean those sensors behind the drum also unplug and plug back in the TCSB I think thats what it is anyway. Its the board under the toner area. After I do that it usually works just fine. Good luck

I've had that board go bad, replacing it fixed the issue. I'd try clean the sensors first, even removing said board and blowing it out with some can air. Re-run all the drum adjustments and see if that fixes it.

Finally the problem is solved

It was the Toner Problem. My Toner bottle was just having a little toner Approximately 1" . Amazing why not it shown Add Toner soon like other machines before going less toner.
