What's happening is that the ribbon is failing to advance in the cartridge.
This can be due to :

  1. Not seating the cartridge well into its saddle.

  2. Cheap loose-mesh ribbons trapping a printhead wire and causing 
     the ribbon to stall while the other print wires burn away.

  3. Damaged ribbon transport mechanism, augmented by #2 possibly.

If it's not too late (#3), make sure that #1 and #2 are not the cause.
You can tell if the ribbon is too loose a weave if you can see daylight
through it. 

I safegard against #1 by always moving the print cartridge back and forth
and observing the ribbon advance mechanism at work (or if it's in bad
lighting, FEELing the ribbon advance.

Hope this helps.
