Is my printer broken after years of no use?

It's a Brother DCP-330C inkjet printer that was not used for more than 3 years. After using the printer's auto cleaning feature, this is what I get (it's Windows' print test page, but with nothing black, and colors look weird): I removed the ink cartridges and they are all about half full. The magenta one was leaking through the hole that connects it to the printer. After putting them back and auto-cleaning again, the test print result is the same. I could try buying new cartridges but if that doesn't work I would buy them for nothing... do you think this is a printer problem or a cartridge pr
