Maintenance
Replacing the Ribbon Cartridge
Important!
Make sure you have the correct replacement ribbon
for your printer. The wrong ribbon will not print when
installed in your printer. Look for the printer model
number on the ribbon package.
Ribbon Cartridge Handling
Leave unused ribbon cartridges in their
packages until needed.
Careful; the ribbon ink may cause permanent
stains.
Ribbon ink on skin or clothing can usually be
removed with soap and water.

Make sure the printer is turned OFF.
Open the access cover, set the Paper Thickness
lever to position 10 and center the printhead.
CAUTION!
The printhead may be HOT!
Holding the sides of the ribbon guide, slope it
up and out to remove it from the carriage. Make
sure the Ribbon Guide is aligned with the cut-
away on the Pull Up Roller Assembly.
