Corrective Action
1. Adjust the forms thickness lever
setting. (Print quality can be affected if
it is too loose or too tight.)
2. Adjust the paper tension horizontally
by moving the right tractor. (Print
quality can be affected if it is too loose
or too tight.)
3. Make sure the ribbon threads
around the ribbon guides and between
the hammer bank cover and ribbon
mask, as shown on the ribbon path
diagram. Turn the ribbon spools to
ensure that the ribbon tracks correctly
in the ribbon path.
4. Clean the printer (page 80).
5. Replace the ribbon (page 54) with
an approved ribbon.
1. Reset the forms thickness lever for
thicker paper.
2. Check the paper slot for foreign
material.
3. Adjust the horizontal paper tension.
Set the forms thickness lever for
thicker paper.
With the printer off-line, press UP and
DOWN simultaneously so that the
display reads "UNLOCKED." Display
the configuration option you want to
change. Press ENTER when the option
is on the message display.
