Recently my color printer HP OfficeJet 8600 is giving me some kind of white lines in the copies of the photo prints that I take out from this printer. Donít know what is that but it is coming out from every single copy. It looks to me as if the roller of the printer is to be blamed but I donít understand how can I get rid of that lines? Is there any method by which I can check what is causing that problem? Thatís what I want to know? If you all have any suggestions or replies for the same then do suggest me about it. Your suggestions would be appreciated thatís all I can say over here.
