IBM 4232-302 -- Ribbon Removal

The 4232 has a curious ribbon cartridge with an integral mask carrier. The mask carrier fits over two 'square', tapered posts at either side of the printhead's nose, and self-latches onto them at their notched bottom ends. Here's a view of a left side post.

To remove a ribbon, you're supposed to tip the mask carrier toward the platen and pull it up off the posts, but it can be obstinate. Try too hard and you're liable to break the thing, like I did.



If a ribbon cartridge's mask carrier gives you a hard time, get a small screwdriver under it and pry it up, like so.

The good news is that even though the thing is broken, it still fits in place and works.
