Can dried up ink in my Brother printer be cleaned out?

I left the U.S. a little over a year ago and left my Brother printer with an ex-boyfriend to sell for me. I returned to the U.S. for a visit a few months ago and found out that the printer was never sold. Well, he knows nothing about printers and I thought he would sell it quickly so I never bothered trying to teach him how to regularly run it through the cleaning cycle. Of course I found it unusable. I was already returning to Peru with an extra suitcase for U.S. purchases and had room for the printer, so I brought it back to Peru with me hoping I could find someone to get it working again so I can use it with a power converter.

It's a Brother MFC-490CW with 4 colors of ink total. Would a competent tech be able to clean out the dried ink and what would it involve? My Spanish is limited, so I want to know more about what I'm dealing with here before I try talking with technicians.
