odd nozze check pattern for epson 3000

I have an epson 3000 and hadn't used it in months. I knew I had to do
a lot of cleaning to get it going again, so I did clean the heads,
windex the cleaning pads, refill the ink reservoir, and got a test
pattern to finally print. The test pattern is weird, though, it's
missing ink in areas and has excess lines all over the place. Take a
look at it at:

I want to know if I should keep on trying to fix this or just trash my
printer.
