1. Get
a damp paper towel.
2. Remove
the cartridges from the printer
3. Below
the cartridge carrier is a flap that you can press down (see picture). You
have to hold this down to get to the "feet" in the next step.

4. Use
the paper towel to clear the lint and extra ink from the bottom of the
three "feet" on the cartridge carrier (see picture). It
is the lint that is causing the streaking so you might need to use your
fingernails through the towel to scrape all of it off.
