      Sometimes the LED units don't go all the way up when you move the blue handle to lock in the IU's (image units) I think that's been a problem here and there with those boxes, although I've never seen it.
      Color is not 4 times harder... it's 65,000 times harder. They call it "TECH MODE" for a reason. I have manual's and firmware for ya, course... you are going to have to earn it.

          Have you printed out the 4 seperate colours to see if they are all O.K or not?!

          Is it when your copying, printing or both?

                      the yellow and cyan are the ones that are off,the magenta is not as bad and the black is fine.

                                      stevee - I've run into a similar issue where 2 inches from the edge of the paper the color is just washed out or almost negative. This shows the most during a Gradient print. What the issue was for us was a bad Cyan Imaging unit, which threw off any of the color grid that cyan was used for. I would try doing a Gradient and maybe even a solid page to see if this is 1 color causing the issue or several. If it's universal I'd look at Transfer Belt like everyone else has stated.

                                      Impulse - are you installing a new HDD or are you replacing one? If you're replacing you can try to do a logical format, then if that dosn't work try a physical format followed by a logical format. If you are putting in a NEW Hard drive, make sure you have the HDD bracket and it's a relatively easy install followed by telling the C450 in service mode HDD is on, then logical format and you're set!
