Transfer Ribbon
The choice of a suitable transfer ribbon is important for the print quality of your
printer as well as the useful life of the printhead.
NOTICE !
Hermes 4N and Hermes 4F are equipped with a near edge printhead. For
that reason choose transfer ribbons which are especially designed for the
use with near edge printheads.By using other ribbons only a poor print
quality is reacheable. The printouts have no brilliance, the surfaces are
dull.
For Hermes 4F and Hermes 5F standard transfer ribbons are usable.
CAUTION !
Transfer ribbons of inferior quality may cause premature deterioration of
the printhead !
The material must be extremely resistant to high temperatures to avoid melting
the ribbon with the printhead.
The heat which arises during printing must be carried off by the label and by
the transfer ribbon itself. Transfer ribbons of inferior quality are often poor heat
conductors. This may cause overheating of the printhead in spite of electronic
protection.
Poor transfer ribbons also tend to lose parts of the coating which leads to
accumulating dirt on the printhead and the sensors. With some ribbons the
color rubs off and soils the printhead. All of these effects contribute to poor
print quality.
We have carried out numerous tests with many different ribbons and we
recommend you use transfer ribbons made by well-known/ brand
manufacturers only. Depending on the label material, several transfer ribbons
may be suitable.
The quality of print is determined by the right combination of these materials.
The recognition of the transfer ribbon is sensed by the rotation control of the
transfer ribbon unwinder, rather than by photocell sensors. As a result, ribbons
with a thinner coating or those with a colored coating can be used safely. To be
able to print all labels up to the exact end of the transfer ribbon, the length of
the uncoated trailer is limited.
NOTICE !
When buying transfer ribbons, make sure that
- the trailer of the ribbon has a maximum length of 4 in (100 mm).
- the trailer is made of nonconductive material of is coated with a
nonconductive film.
- the trailer easily can come loose from thecardboard core (F<3N).
