NOTE
Material damage due to improper handling!
The printhead can be damaged by improper handling.
fDo not touch the bottom of the printhead with the
fingers or sharp objects.
fEnsure that the materials are clean.
fMake sure that the material surfaces are smooth. Rough
materials act like emery paper and reduce the service life
of the printhead.
fPrint with the lowest possible printhead temperature.
The device is ready for operation when all connections
have been made, and the materials and, if applicable,
the colour ribbon have been loaded.
7.1 Cutting mode
A cutter is available for the TT431 as an accessory. With
the installed cutter, materials and continuous material
can be automatically cut off after printing.
7.2 Tear-off mode
In tear-off mode, materials or continuous material is
printed. The print job will be processed without
interruption. After printing, the consumable material
strips are torn off by hand. For this operating mode, the
tear-off plate must be installed.
