Poor print-qualiity after replacing 1 of 4 toners. What did I do wrong ?

[Preben Kvist]

I replaced the black toner-cartridge on my Samsung CLP500. It has 4
cartridges one black and three color. After replacing the black cartridge
ALL colors on the prints are weak. Any ideas about what I did wrong and how
do I fix it ?

Best Regards

It could be a coincidence and some other bit is getting ready to want
replacing, I'm not sure what parts it has there, but there could be a
fuser roller or an OPC drum that is coming to its end.
