I did it on mine. Was not difficult at all. Just take your time and ask questions if you are not sure of something.
Just my personal opinion, if you are replacing the black might as well replace the color while you have it all apart. Also might as well replace the dampers while you are at it. I see it as preventive maintenance but I know everyone does not see it that way...
Oh yeah, don't forget to unplug the printer before you take it apart (like I did) otherwise you will end up blowing one of the fuses on the main board like I did and I can tell you from experience that it is not a fun thing to replace.
