Doing a forced toning does not guarantee that toner is added. If Vt does not change, fresh toner is not entering the developer. A common problem with OEM toner is bottle length being too short. Confirm that the bottle is actually turning. Check that nothing is obstructing the toner path from the bottle to the development unit.
