the ink was running very low, black was completely out so I just replaced the black ink cartridge (just 281 black cartridge). Then I tried to print some documents in black and white and it made all the normal noise but a plain white paper came out, nothing printed on it! I tried to trouble shoot, went to tools and tried to align. The black grid printed out clearly, then it said to put in on the screen for scanning, I tried and it said error. It said if it is not smudged, try aligning again, I tried again and the same thing when I tried scanning. It said error. But it did print black during the alignment so I tried printing again and just got the same blank page. Please help!!!
