There are two ways of replacing the ribbon. You can install a new ribbon 
cartridge in the printer or refill the old ribbon cartridge with new ribbon 
from a ribbon subcassette. Appendix A lists order numbers for ribbon 
cartridges and ribbon subcassettes. The following procedure is for ribbon 
cartridges. For ribbon subcassettes, refer to the instructions shipped with 
the subcassette. 

To replace the ribbon cartridge: 

1.  Turn off the printer. 

If the power is turned off during or immediately after 
printing, turn on the power again.  Verify that the print 
head has moved to the ribbon replacement position, and 
then turn off the power again. 

2.  Open the front cover of the printer. For easy installation, slide 

the print head carriage to a position for replacing the ribbon 
cartridge (indicated by the triangle marking on the front of the 
upper cover).
