Printhead
¯If you do not have any professional
ESD protection equipment (ESD
wristband,ESDshoes,…),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 may
be carrying.
Impurities such as lint and colour particles
from the thermal transfer ribbon may
collect on the printhead during printing.
This can degrade the printed image
considerably. Noticeable effects:
•Differing contrast on the labels
•Light stripes in the printing direction
¯Clean the printhead [2A] and the print
roller[2B]regularly,andalwayscleanthem
before inserting a new ribbon. When using
direct thermal mode, always clean them
before inserting a new material roll.
PCleaning the print roller: See Section
Cleaning/replacing the print roller on
page 12
CAUTION! - Electrostatic discharges or contact with sharp edges can
damage the printhead.
«Protect the printhead [1A] [2A] from electrostatic discharge (ESD) when
performing maintenance work or cleaning!
«Avoid touching the thermal transfer [1B] printhead with bare hands!
«Do not allow sharp objects to come into contact with the thermal edge.

Further Maintenance Tasks
Cleaning the punch sensor
With frequent use of the printer, the punch
sensor is gradually contaminated with lint.
Large amounts of dirt can lead to problems
with punch recognition.
To free the punch sensor from dust and
abraded particles:
1. Lift the cover [24A] gently and push it
downwards.
2. Pull out the sensor fitting [25]].
3. Clean the gap [25 [B] with compressed air.
¯The transmission sensor is situated in
the upper and the lower part of the sensor
fitting on a level with the indicator [25A].
The reflex sensor is located 5mm further
out in the lower part.
CAUTION! - The sensor surfaces
are susceptible to scratches!
«Do not use sharp objects or
solvents when cleaning the
sensors!
