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?
