Replacing the Printer Ribbon
The printer ribbon supplied should give many months of reliable service,
but when the printout becomes light or intermittent, the ribbon needs
replacing. Any adding machine ribbon equivalent to the ribbon supplied
with the calculator or either of the products listed below can be used as
a replacement.
General Ribbon Co., type E200, black and red intense ribbon.
Columbia Ribbon Co., type 43, black-red record, double-spool
ribbon.
When replacing the printer ribbon:
1. Notice the path of the old ribbon before removing it. (See
drawing below.)
2. Be sure the black portion of the new ribbon is up when
installed.
3. Press PAPERT to draw the ribbon taut before closing the
calculator top cover,
