image problem

[jokacross]

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

I made the Image stabilization+Initialize and the first print become like this:
8822
After 16 prints looks like this:
8825

Then I made the gradations adjustments the 3 of them and the first print become like this:
8823
and after 16 prints looks like this:
8824

The original doc is this:
8826

What is this?

One mor thing in the gradation adjust the Conv. Value I cant never get the Right values! In the tree of them

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.

Hi there!
I´ve had asimilar problem but the customer uses no original KM-toner and the transferbandunit was to old (not by prints but time!).
With the new transferunit it became better odd the OEM-toner.
