Horizontal lines in Black ink on a 7855

[Z28Joe]

I don't use the printer often so it's like new. When I print the black gives me horizontal lines, some lines don't show at all and some are too light. This problem gets worse with each page I print. I have used half my ink cleaning the heads so I figured that's not the problem. I've checked the manual, the internet and here with no luck. I think I have printed about 20 pages since purchased. Any help would be great. Thanks          PS. the color seems fine on the test page.

Replace the black ink cartridge, the ink has dried in the print head.
