Had a pretty bad paper jam awhile back, printing has not been the same. Only printing half lines throughout the entire page. I ran the "clean cartiridges" that did help in the beginning but not anymore. I have installed new cartridges, ran clean cartridges after that again. Still not printing correctly. (Have used NOTHING BUT HP CARTRIDGES) Now, everything i print is only half lines (or white lines through the black print) however you want to describe it. I have used the "HP priht doctor" I have gone through all the self help steps. I am now wondering if there has been some damage done to inside of printer due to paper jam.
