C6500 error after changing the cyan drum

[drodas78]

Hi. One day after replacing the cyan drum unit I have the print error that you can see in the attached file. The red arrows show the error. I think that the drum is not well cleaned by the blade and it is repeating the image that just print. This is a new drum unit and I want to be sure before change it again that it is a drum unit problem. Any ideas? Can I change the cleaning blade of the previous drum to this one? Is in fact a bad cleaning blade or the whole unit drum is defective? Some one has have this problem before?

Thank you for your help.

Not sure how familiar you are with this machine so don't get upset at this suggestion: When installing the Cyan drum did you remove the red screws (one front and one rear) that hold the cleaning blade away from the drum?

Oh!!! I'm familiar with the machine. I have changed drum units several times but when changing the cyan drum unit, I was in a hurry because of a trip and I forgot to remove the screws. My fault. I wrote here before going to the machine and I'm glad for doing it. Thank you for answer. This forum is great!
