I have an all in one printer from HP and just replaced the black ink cartridge. I'm supposed to scan the alignment page to align the cartridge to ensure the best print quality. However, when I print the sheet the ink is really faded in certain spots even though it is a brand new cartridge. The problem is my scanner won't even read the alignment page. I can still print things but the quality is quite poor. I have tried cleaning the cartridges but that didn't seem to help. I'm not sure what else to do? I did notice the color cartridge is pretty well empty. Could that be affecting the print quality at all, even though I just need black ink?
