Recommendation
Check that the ribbon is seated correctly
and that the pins at either side are
located properly in the holes in the ribbon
carriage.
Check that the ribbon moves freely in the
cartridge.
If you have been using the ribbon for a
long time or for a large amount of
printing, it may need replacing.
It is also possible for the print head to
wear out if the printer is used frequently
and for long periods at a time. Contact
your dealer for a replacement print head.
Never attempt to replace it yourself
because other parts of the printer should
be checked at the same time.
If you have removed the color option kit,
consult the user’s guide to check that the
ribbon carriage is set correctly
This can usually be corrected by
changing the setting of DIP switch 2-4. If
that does not solve the problem, you may
need a different cable.
If they are international characters,
check the settings of DIP switches 1-6 to
1-8. If they are graphics characters, see
that your software is correctly installed
and that you have correctly set DIP
switches 1-3 and 1-4.

Check the settings of DIP switches 2-1

the correct paper size and that skip-over-
