always use ribbon that is at least as wide as the media.
the smooth backing of the ribbon protects the printhead from wear and premature failure due to excessive abrasion. (for direct thermal print mode, ribbon is not used and should not be loaded in the printer.)
1. align the segments of the ribbon supply spindle.
2. place the ribbon roll on the ribbon supply spindle.
make sure that the core is pushed up against the stop on the ribbon supply spindle and that the ribbon is aligned squarely with its core. if this is not done, the ribbon may not cover the printhead entirely on the inside, exposing print elements to potentially damaging contact with the media.
3. to make ribbon loading and unloading easier, make a leader for your ribbon roll if one is not present.
4. tear off a strip of media (labels and backing) about 6-12" (150-305 mm) long from the roll. peel off a label from this strip. apply half of this label to the end of the strip and the other half to the end of the ribbon. this acts as a ribbon leader.
5. open the printhead and thread the leader and attached ribbon through the print mechanism, under the upper roller, and past the platen roller as shown.
6. before wrapping the ribbon around the ribbon take-up spindle, ensure the ribbon hook is placed correctly. the ribbon hook fits snugly in the notch (see figure 24).
7. place the ribbon (with leader) around the ribbon take-up spindle and wind counterclockwise for several turns (see figure 23).
8. close the printhead.
