I'm getting this code(F-26-1)on a knoica 7135 I guess it's a toner density sensor issue. when opening up the right door and looked at the drum it was black. Removed the drum assembly and cleaned and inspected, toner density sensor clean also cleaned the charge corona assembly. when I started the michine up it gave me the same code. The machine has a generic drum also. could this be a charge corona problem or a tds problem. Thanks
