welcome to s101:Welcome: search function has tons of similiar issues.
it might be worth having a tech come out and take a look at it for you, set this machine up right, considering you most likely got a deal on the used printer in the first place.
these printers are tanks, and could easily run smooth for the next 6-10yrs with proper user maintenance... assuming they're setup correctly on the front-end.
otherwise pictures and exact events leading up to the failure would be helpful to toss out here, and hopefully we can point out something simple for a quick-fix.
can o' worms is most likely your diagnosis, however.
(start with a new wiper blade, carriageout & clean the capping station, run a disway wash, set a 99min nozzle wash, run a fillupink, set another 99min nozzle wash, and then do a test print.)
