Replacing the Ribbon Cartridge

If printing is too light because of ribbon wear, replace the ribbon cartridge. Appendix A lists the order number for the ribbon cartridge.

The replacement is almost the same with the installation except that it involves removing the old ribbon cartridge and unpacking the purchased ribbon cartridge from the carton. The installation of the ribbon cartridge is detailed in the section “Installing the Ribbon Cartridge” in step 3 of the Installation Guide. This section describes only the removal of the old ribbon cartridge.
