Cleaning
Generally, the following three steps are performed by the user.
Each time the transfer roll is replaced
1.
Wipe the line of heating elements of the thermal head with a lint-free
cloth dampened with 90% isopropyl alcohol. Also clean the thermal
head's transfer roll guide located just above the row of thermal head
heating elements.
2.
Open the top cover and wipe the surfaces of the black rubber rollers
with an alcohol-dampened cloth.
3.
Clean the pick rollers. Users can either do this with an
alcohol-dampened, lint-free cloth or use the pick-roller cleaning tray
provided in the cleaning kit.
4.
Clean the feed roller. A dirty feed roller is most often the cause of
media jams.
Scrub vigorously
with an alcohol-dampened, lint-free
cloth. Be sure to close the gray plastic paper guide when done.
