LaserJet4 smudges

I got the wavy paper problem fixed thanks to the repair kit from www.fixyourownprinter.com, but now I need to find a solution to the black smudges that are on the right hand side of the paper. They seemed to have lighted since I fixed replaced the roller assemblies. The marks are about ½" wide. It's not solid black, just puffs.
I don't recall exactly when they started. We've been living with this problem for quite some time now. I do know that the current toner cartridge isn't an HP, it's the CompUsa brand. Could this be the cause? Does anyone have a clue as to what is causing these marks? Any suggestions would be greatly appreciated.
