Hello,

First what you have cleaned is the patch and registration sensors . Did you open the shutter and clean the sensors ?

Is the job printed or copied?

Are you using fiery ? or a simple driver ?

When the color is changed? is it after the first gradation adjustment ? and does it stays the same afterwards ?

When you clean the gradation sensor give me your update .

Check the P-Pascal values under the cover , check the photo.

Make Sure when you need to test. Perform the Auto-Gradation full adjust first then test .
Best Regards
