Hi,

originally had printer failure a month back. so i replaced the printhead. for a few weeks it worked fine. then it started banding. run the printhead clean cycle 3 times it got better but still not good enough. the printhead supplier sent out another one sent back the presumed new faulty one. So fitted the new replacement printhead, again few weeks later banding again? so it cant be a printhead issue? i know they have a service station which i have cleaned but i am lost. printhead cleaning gets it better but still got banding

 

any help any use would be useful
