ATTENTION
Incorrect handling can damage the printheads!
► Do not touch the underside of the printheads with your
ngers or sharp objects.
► Make sure that the labels are not contaminated.
► Ensure the smooth surface of the labels. Rough labels
act like an abrasive and reduce the service life of the
printhead.
► Print with the lowest possible printhead temperature.
The printer is ready for use when all connections are es-
tablished and the labels as well as, where necessary, a
transfer ribbon have been inserted.
7.1 Setting up one-sided printing
The bottom printhead can be switched o if required. This
makes it possible to process labels in a similar way to
single-sided printers.
► Activate the parameter Settings > Print > Disable bot-
tom head.
► Open the bottom printhead.
► Remove the transfer ribbon from the bottom print unit.
► Send the print job with single material width.
7.2 Ribbon-saving function
This function detects longer areas where there is no infor-
mation to print. For this time, the bottom print assembly is
set to inactive by raising the printhead during the label feed
and suppressing the ribbon transport. This means that less
transfer ribbon is used. The minimum length of the unprint-
ed area for the ribbon-saving function is set in the rmware
and depends on the print speed.
The ribbon-saving function can be permanently activated in
the printer conguration.
7.3 Avoiding material loss
The print information for a section is applied to
the material at dierent times at two dierent lo-
cations in the material transport direction.
Therefore, the following behaviour occurs whenever print-
ing is interrupted:
Material printed on the bottom side is pushed to the up-
per printhead to complete the print without the following
material already being printed on the bottom side. A return
transport of the material to the bottom printhead is not per-
mitted for reasons of safe material guidance. This results
in unprinted and thus subsequently unusable areas in the
material strip.
When operating with a cutter, the material loss is at least
110 mm for continuous material.
When using structured materials where the print image
must be synchronised with the material transport, the loss
can reach a length of more than 300 mm.
To keep material loss low, interruptions of the continuous
printing operation must be minimised:
– Print jobs should only be interrupted when absolutely
necessary.
– Print jobs with only a few print sections, especially jobs
with only one print section, should be avoided.
– Foreseeable error situations should be avoided, see
chapter 7.4. In error situations, the loss of material is
particularly high, as material that has already been print-
ed must usually also be discarded.
Optimising the print
► To minimise material losses, activate the parameter Set-
tings > Print > Double print optimisation.
With this setting, a print job is not immediately processed to
the end. The printer stops the material at a position where
a subsequent job can be printed without blank labels and
waits for new print data. After receiving the new data, the
previously unnished print job is automatically completed
and the new job started without an intervening blank label.
If no further print data is expected, the job can be complet-
ed via Complete job.
