Digital BW, The Print

Ok, I was given a 2200. 6 months ago, the printer had a clooged head. He tried to unclog it with some unclog liquid from the internet. After a few purges, nothing printed anymore.
The printer stayed with no cartridges in a box for 6 months.
Now i got it. Last night i used some blue windex and tonight i tried a nozzle check. The printer acts like it's printing but the page is blank. I did a purge and same thing. I just put back some windex to sit overnight.
Anything else  i can do or there's no hope.
Thanks.
