If it’s constant I would be looking at the main drive assembly. Possibly one of the clutches. Assuming you’ve checked the drum

you can run a motor test and check which motor is causing the noise
Copier->Function->Install->TONER-S in service mode also makes the same noise
i vacuumed inside the machine but the sound is still there
Did you take out the hopper? The time dropping to 119 so quick means the DV has enough toner. Have you put in a different drum unit just to rule that out? It’s easier than removing the hopper but it sounds like your hopper making the noise.
