    Remove the black hub unit to make sure there is no blockag. Also you for the mean time manually fill the developer unit with some of the tonner but it will fade again when it is used up.
    Thanks guys for your reply I solved it and the problem was blockage in the black hub unit. It was not supplying enough tonner into the developer​ unit

      Thanks, I'll have to look into that. My adjustments to the lower and upper limits did not work, I'm getting en error 20-0492, which is related to those readings.
