I have a HP E609n printer. It is two years old and has printed fine until today. Last week I used the printer until the black ink was almost completely gone. Today I put a new black cartridge in but the black print is streaked. I cleaned the printer 5 or 6 times using the automatic cleaning method which helped a little. Then I removed the print head and cleaned it
with a Q-Tip. There were several wads on black ink on the head and in the part that receives the head. I cleaned both with only Q-Tips. The print is still very streaked. All of the other colors print well per the test sheet.
What do I do now?
