I have a customer with a Ricoh 3245C that has an add black toner message, they are using after market toner and devolper unit for the black only has 10K on it. They had 3 toners there for the black all were generic and all did this problem. I did get it to a ready state but it said black toner is low. Could it be the toner cartrige or should I go ahead and order the toner pump?
