I have a Konica 7145. After changing the developer and running 500 copies, the Auto Toner Supply comes on (its setup to run after 500 copies). After running for 3 min it continues printing copies but only 10 before it comes on again. Then after 3 min I can print another 10, and then again the Auto Toner Supply comes on. I cleaned the toner density sensor inside the toner supply unit. I am not sure what else could cause this problem. I did do a factory reset back a few weeks ago. Could this be the problem or is there something else wrong?
