I was just printing something out when I noticed the ink wasn't coming out right. The ink began fading and some pages had horizontal blank streaks crossing evertything out. This screenshot gives an example of what the problem looks like: One thing to note: this is only a problem with the black ink; color prints perfectly fine. I tried the 'clean' option presented in the above dialog box, and also the 'prime' option. Neither helped. Does anyone know what the problem is? Did the ink dry out or something Is there some way to fix this and prevent it from happening again? ... I had something like this happen before to both the black and color cartridges about a year ago, and was only able to solve that by completely replacing the cartridges.
