Brother printer/scanner/copier DCP-195C (Purley CR8)

Old printer, worked ok until recently.
We hadn't used it for a while, and the black printer head seems to be blocked.

Photo shows a test print that was taken recently, and an ink stain.

At the moment it's giving an error message to replace Yellow Ink. I haven't done that, in case anyone just wants the cartridges.

We used compatible cartridges with no problem, and 9 unused cartridges are included.

Maybe someone can repair it?
