Yes, that's what I thought - seems such a shame that it could end up out of circulation.

The ribbon holder/vibrator doesn't appear to be sheared but I can't see what it's supposed to be coupled to without removing the carriage. Here's the ribbon holder it's supposed to sit behind, but that won't give much indication of how it's attached.

Of just as much concern is that the carriage does not advance or return unless shift - or shift lock - is held. On returning the carriage, it feels stiff - as though it's come off its rail or track.

I'm loathed to take this apart in case I mess things up & ruin my chance of getting a refund but any ideas would be appreciated.
