Dell 2150cdn printing gray instead of black

I replaced the Imaging Drum in our 2150cdn on 9/24/14. The printer has printed fine for two months but now prints gray instead of black (colors print accurately). I replaced the black print cartridge with a new one but still get gray print-outs instead of black. I tried the "non-Dell toner" setting in the configuration menu (using toner from LD Products), but still get the gray print-outs. Any helpful suggestions appreciated.
