Have you replaced the transfer charger housings? They burn thru and cause light copies, also will register transfer error codes. Do you have any codes logged? Also, check the drum potential sensor is in the right position.

i tried t/s unit dv unit cleaned clutchs that drive part of the dv unit there are NO codes the machine will run and make great copies then just like you flip a switch they are bad again and some one it will just start to make good copies again all on its on you dont have to even open it up it just starts making good copies again.. any ideas would be helpful I am leaning toward a DPS or high volage board..
