Are you sure that the transfer cleaning path is not blocked or the coil has failed and used toner is not carried away to the waste bottle, but rather smeared on the page?

This problem come from Brush roller, brush roller replace with new drum.

Drum Unit, developer unit, Charge corona unit and Transfer Belt with Blade was changed

I think is a electrical problem, after the copies became dirty, if you make one copy, the copy is clean ...

A drum cleaning unit that is due for rebuild or replacement will give this symptom. During a multiple copy run, waste toner will build up in the cleaning unit and cause the blade and brush roller to not fully the drum surface.

The other thing that can cause this is the HVPS starting to go flaky. Charge voltage drops slightly as the HVPS heats up form being on constantly. In the time between copy jobs, the HVPS cools back down.

i had the same problem, its the Transfer Belt or the charge roller under the belt....check also the Bias voltage (SP 2201), 550V is normal, try to set it lower.But the best thing is to change the transfer unit

I also face same problem
When I make 10 prints starting 2 prints were clean and after that print becomes dirtier.
I found that opc drum crosses its recommended life.
Issue resolved by replacing new opc drum.

Check the cross frame between the drum unit and the fusing unit that the heat shielding for the drum unit is mounted. On the 907, 1107 and 1357 there is a flange on the bottom that toner can build up on. When enough builds up, the trail edge of the paper can rub against it. Also check the bottom of the drum unit.
