52 Ploblem Solving, Maintenance, & Service

…I’m getting strange symbols, incorrect fonts, etc., when I try to print a document?

The printer driver you have engaged does not agree with the emulation selected for

your printer.

To check the emulation selected, first make sure paper is loaded, then press the SEL

and SHIFT buttons simultaneously to enter the MENU on your printer. Next, press

the GROUP button: this will print the emulation selected.

If the emulation is not the one you want to use, press the SET button to change it to

the one you want before exiting the MENU (to exit, press SEL and SHIFT buttons).

If the emulation is correct, check your software documentation on how to select a

printer driver, then check to be sure that you have selected one of the drivers listed for

that emulation on page 49). The closer the driver is to the top of the list, the more

compatible it will be with your printer. If your software doesn’t have any of the indi-

cated drivers available, check with the software manufacturer to see if they have added

any additional drivers since you purchased your software.

If you have embedded any printer commands in your software, check to be sure that

you entered them correctly.

…I’ve installed a brand new ribbon and the printing is smeared and streaked?

The plastic shield on the ribbon is either loose or missing. The shield must be left on

the ribbon when you are installing the cartridge. To remedy this situation, move the

printhead to the center of the platen (careful – printhead may be HOT!) and lift off the

ribbon cartridge. Check the ribbon shield. If it’s loose, secure it in place properly. If it’s

missing, locate it and reinstall it.

…there are dots missing in my printouts?

The head gap may not be set correctly. Try moving the head gap lever to a lower

setting. If that doesn’t help, the printhead may be damaged; call for service.
