WHEN THERE’S A PROBLEM
Given below are some operational problems you may encounter
and their solutions. This typewriter has been carefully manufactured
and most problems result from invalid procedures and are not likely
to be a machine failure. The sections below will help you correct a
problem or determine if a service technician should be called for
help.
Typing
Quality
Problems
Characters print too closely or too far apart
The selected print pitch may not conform to the pitch of the
printwheel. Determine the pitch (that is whether it is 10 or 12) of the
printwheel in use, then set the print pitch accordingly.
Each word is underlined or printed in boldface
Hold down the CODE key and press the U key to clear the
Underlining feature.
Hold down the CODE key and press the B key to clear the Bold
feature.
Printed characters are missing or broken
Check the ribbon for proper installation and proper feed. Make sure
that it leaves and reenters the cartridge correctly and that it is not
torn or broken.
Inspect the printwheel for a broken "spoke”, that part of the wheel
that holds the characters.
Check that the printwheel is set correctly, refer to page 9.
Correction Problems
Characters do not erase
Check that there is still unused correction tape remaining in the
spool.
Check that the correction tape is properly inserted, refer to page 8.
Check to see that you are within the Automatic Correction zone. The
use of accented characters, and certain other typing operations,
may decrease the number of characters which can be corrected
with the Automatic Correction feature.
