[Error Code] Error Code C2424 Bizhub C5501

[bpifer15]

Changed out the K developer. Put everything back together and now get an error C2424 which is "After the developing motor/K (M23) is ON, or TCR sensor/K (TCRS/K) initial adjustment started, TCRS/K detected lower than the specified value after the specified time passed." Does anyone know how to fix this? Not very experienced on this machine so some detail would be appreciated. Thanks guys

Solved. I believe, but not 100%, that it was because I reset the count for the K developer prior to running the Toner Density Sensor Init. I had to run it twice on the K unit, but the error did go away
