Printhead
¯If you do not have any professional
ESD protection equipment (ESD wrist-
band, ESD shoes, …), please place one
hand on an earthed object near to you (e.g.
tap or radiator) before touching the device
to discharge any static charge your body

timal print head condition. It is recommen-
ded this is done when replacing the roll of
foil, using cleaning paper (article no. 5030).
Cleaning the Printhead
Impurities such as lint and color particles
from the thermotransfer foil may collect on
the printhead during printing. This can lead
to a noticeable detrimental effect on the
printed image, shown by:
•Differing contrast on the labels
•Light stripes in the printing direction
How to clean the printhead:
1. Switch off the printer.
2. Open the printhead pressure lever. The
printhead folds upwards.
3. Remove material and foil from the printer.
Cleaning with the cleaning pen
4. Applying light pressure, go over the
thermotransfer printhead (1) a few times
with the cleaning pen (Fig. 1).
CAUTION! - Electrostatic discharge
(ESD) or contact with sharp objects
may damage the printhead!
«Protect the printhead from electrostatic
discharges when performing mainte-
nance work or cleaning!
«Please try to keep bare hands away
from the thermotransfer printhead (1)
as much as possible!
«Do not allow sharp objects to come into
contact with the thermotransfer prin-
thead!
