2. Moisten (do not soak) a soft, lint-free cloth or cotton swab with
99% pure isopropyl alcohol. Rub gently along the length of the
printhead, removing any buildup of residue on the printhead.
3. Allow the alcohol to evaporate completely before using the plotter.
CAUTION: Do not touch the printhead with your fingers or other ob-
jects. Skin oil will contaminate the printhead, which diminishes plot
quality and shortens the life span of the printhead.
VORSICHT: Den Druckkopf nicht mit den Fingern oder irgendwelchen
Gegenständen berühren. Fett oder Öl verschmutzt den Druckkopf,
wodurch die Druckqualität vermindert und die Lebensdauer des
Druckkopfes verkürzt wird.
Cleaning the platen roller
After prolonged use, the platen roller picks up fibres from the paper
passing above it. These fine fibres collect and compact on portions
of the platen roller, creating bumps. The uneven surface of the roller
may cause the printhead to contact the passing paper unevenly,
producing a blotchy or faded plot.
Clean the platen roller when it appears dirty, or after approximately
three rolls of paper or film have been plotted.
Lightly wipe the roller with a soft, lint-free cloth moistened in 99%
pure isopropyl alcohol, turning the roller as necessary to remove
paper fragments and dust.
