Problem ____________________________________________
Ink smears on the paper when I print narrow columns.
Solutions
The head gap could be too close. Check that the Head Gap Lever
(1) is set correctly (see "Adjusting the Head Gap" on page 11).
Problem ____________________________________________
I've installed a new ribbon and the printing is smeared and
streaked.
Solution
The ribbon shield (1) is either loose or missing.
1. Remove the ribbon cartridge and check the ribbon shield.
2. If it is loose, secure it.
3. If it is missing, find it and install it. If you cannot find it, see if you
have an old ribbon cartridge with the shield still on it. If so,
remove the shield from it and put in on the current ribbon
cartridge. If not, replace the ribbon cartridge.
