sounds like an improperly stored printer. there could be clogs everywhere. you need a comprehensive cleanup of the lines. and possible replacement of heads/dampers/capping stations.
i would suggest getting a really good tech, and request for a comprehensive cleanup. there are some great third party suppliers of parts/service here in s101. just ask around by creating another post.
i know that you mentioned that you used up quite a bit of cash already. but i'm sure that people around here will tell you that you need to be prepared to spend a lot more on your machine, and quite a bit more on other equipment that you will need. no amount of explanation, whining, or excuses will change that fact.
good luck!
