Print Engine Operation
Load Ribbon
Load Ribbon
Use ribbon with thermal transfer media. The ribbon must be coated on the outside and wider
than the media. If the ribbon is narrower than the media, areas of the printhead are unprotected
and subject to premature wear.
Figure 28 identifies the ribbon system components inside the media compartment of a
right-hand print engine. A left-hand unit contains a mirror image of these components.
Figure 29 on page 41 shows the print engine with ribbon loaded.
