I do recall having taken rubbing alcohol in a straw (dip in bottle, put finger over top etc., not suck it and [not] see) in order to clean the printhead. Try cleaning the thing. It is not onerous; just get the printhead into the middle, remove the ink cartridge, and drop some cleaning solution down into the works. Soak up underneath with a paper towel. I suspect that's what I did.

I don't think a service depot would be "cost-effective," but you never know. Rather than throw it all out, however, I might be interested in an Apple power supply for the 2200. The one I have is from the Canon equivalent and it's not in the best of shape.

Or sell them on here — Newton users, for instance, like them, as it is one of the relatively few printers to which Newtons can natively print.
