I have a MX922 that prints normally on paper, and in all other colors, but when I print black items such as text on a DVD, the text is ghosted and blurry, as though the printhead was misaligned. However, printing on paper does not cause this issue. I have changed print cartridges, cleaned the timing belt, upgraded the firmware, performed the print alignment test multiple times, and tried different discs with different surface textures - but nothing works. The print alignment test always comes out perfectly on paper. And, as I mentioned above, its only for items that print with black - or contain black. For example, text in colors that do not need black added to them print as crisp and sharp as they do on paper. I've performed every level of cleaning on the heads, but with no effect. I'm assuming it's a defect in the black print head - but I'm open to any suggestion as to how to resolve. Thanks!
