A number of months back, my Pixma 410 started leaving large blackstreaks and smudges on each page I printed. I ran the deep clean maintenance and it improved somewhat. I put a new black and color cartridge in the printer, but the large smudges returned. I tried running deep clean again, but it still leaves streaks and smudges of black ink every time I print a page.
Has anyone else experienced this problem and did you find a solution?
