I think if you wait ~5 minutes you will see the toner add condition. =^..^=

i wait more than 10 min and i don't think that warm-up takes this time

hi.theres many reasons for this malfunction .first you have to check the level of the toner.then you check the sensor which exists on the back of the developer tank .check the tank inside the mechanism and you can try another tank to make sure theres no problem with controller board.check the simulation mode 25 to make sure of the sensor reading.
and i wish you goood luck my dear

Thanks man
