I had 2 MP5001 on a same company they sit just about 25 feet away each other, one had sc 304 ( Charge roller voltage leaked ) at 65K, one at 33K. I checked Sp2001 value was high close to 1900, Mag roller is new kind with shiny surface coating black half of roller, I cleaned mag roller to shiny and check ID senor (not dirty), run multiple copied to tone up copies for good density. Leave and 2 days I got Sc304 again. I ended up to replace drum, charge roller, blade, developer.
Someone had this problem ?
