From bad to worse, an update on my problem.... after going through all the suggestions made in this thread the problem still exists and more. I've changed the platen height, cleaned the wiper blade, updated the driver and firmware, printed from a newly installed different program(Lightroom) from Photoshop, printed from a different computer, tried different USB cables, separated my USB cable from all other cables and cords, turned off high speed printing and lastly ran the head alignment utility from the printer control panel.
Doing all the changes prior to the last effort which was aligning the head made no difference, images still had lines. What is much worse now is aligning the heads has resulted in soft images, essentially going from what had been good sharp prints to prints that have a most noticeable lack of sharpness. I've ran the alignment twice, the second alignment still looks as bad as after the first.
Any ideas as to aligning the heads and getting back the sharpness prints had? I can't find any information as to how to read the manual alignment printout.
Totally frustrated....
