I have a HP but had a similar problem . I tried every setting I read about and anything in between to no avail . I had plenty of ink in the ctgs. . Finally I bought new ctgs. and tried them one at a time . First two no change but when I tried the third one it came out of it . Turned out I had a bad ctg. . The ctgs had been working fine then one died on me . May not be your problem but would be worth looking into I would think .
Think I may have resolved it Ron. It was a combination of print settings, paper but also coincided with a change of cartridges. That is the difficulty when you have a printing problem there are just so many variables..lol
some plaecs recommend that if you change brands you change them all out. something to do with the consistency and colors being different. i've also read it's recommended you print a little bit out to use up and leftover 'old' ink.
