    MP C3001 Light PCU'S

    MP C3001 where all 4 colors were super light, I would to a forced toner supply to bring them back up to looking good but eventually they would go back to being light. So i switched all 4 PCU's and was good for a while but now they are all super light again. And they all seem to go at the same time. Is there maybe a setting that tells it how long to supply toner for? I know when you are doing a forced toner supply you can change the toner supply time, but is there a way to do that for normal operation? Because i feel like maybe it is just not getting enough toner to it. Toner pumps and hoses seem fine because when i do a forced toner supply i can tell it worked. Any thoughts?

    Did you clean the ID sensor assembly? Did you run ACC? Did you clean the laser shield glasses? Is the PTR making full contact with the ITB?
