Printing is patchy, faint,
uneven, or intermittent

All the text is printed
on the same line or
text is printed with an
extra blank line between

Some of the characters
printed do not match
those in the file

Paper feeding problems

Regular gaps appear
in printouts

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.

See Chapter 2 for specific instructions on
loading paper

Check the settings of DIP switches 2-1

and 2-3 to ensure that you’ve selected
the correct paper size and that skip-over-
perforation is OFF:
