Problem 6 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. Problem 7 There are dots missing in my printouts (typically, tops and /or bottom of characters missing). Solution The head gap may not be set correctly. Try moving the Head Gap Lever (1) to a lower setting. If that doesn't help, the printhead may be damaged; call for service. 67 • Troubleshooting
