Hello I have a c450. And here it is the problem

I made the Image stabilization+Initialize and the first print become like this:
initialize+image stabilization.pdf
After 16 prints looks like this:
after 16 prints.pdf

Then I made the gradations adjustments the 3 of them and the first print become like this:
gradation adjust first copy.pdf
and after 16 prints looks like this:
after 16 copies gradation adju.pdf

The original doc is this:

What is this?

Is this the same fault from a week ago? Are the image units chipped? Is the toner OEM? Has the optics been cleaned? You need to do toner add before you do reset and stabilization followed by the grad adjustment. Make sure that the image that is printed (for the adjustment scan) is of good quality or you are wasting your time! When you have got the settings witin the specs switch off the unit and power up again. Do a test printout from the user mode. If your copy/print quality goes bad after a few copies I suspect a stabilizer problem or old IUs.
