R E M A R K S :           How to get a NEW RIBBON for this old machine  ???
===========================================================================
There are  11 mm  CARTRIDGES  for  MATRIX-Printers  on the market, e.g. ...

RIBBON  7/16" ( = 11 mm )  from a  » IBM-4201/4207 - ProPrinter «  Cassette

   ...  Both  RIBBON SPOOLS  have to be wound  COUNTER-CLOCKWISE

                  Have a look at the Restoration Procedure...
