Area Method Interval
Printhead Use a Zebra cleaning pen
to swab the thin gray line on
the printhead, cleaning the
print elements from the cen-
ter to the outside edges of
the printhead.
After every ve (5) rols of
media (or more often if need-
ed). When using linerless
media, cleaning is required
after every roll of media.
Platen Surface (Linered) Rotate the platen roll-
er and clean it thoroughly
with a ber-free swab, or lint
free, clean damp cloth light-
ly moistened with medical-
grade alcohol (90% pure or
better).
After every ve (5) rolls
of media (or more often if
needed.)
Platen Surface (Linerless) Rotate platen roller
and clean with a ber-free
swab and 1 part liquid soap
(Palmolive or Dawn) and 25
parts water. Use pure wa-
ter to clean after soap/water
mixture.
Clean platen only if there
is an issue during printing,
i.e. media not releasing from
the platen. (*see Note below.)
Scraper (Linerless Units
Only)
Use adhesive side of me-
dia to clean scraper.
After every ve (5) rolls
of media (or more often if
needed).
Tear Bar Clean thoroughly with
90% medical-grade alcohol
and a cotton swab.
As needed

hol wipe.

needed).
Note • This is an emergency procedure only to remove foreign
contaminates (oils, dirt) from the platen that can damage the
printhead or other printer components. This procedure will shorten or
even exhaust the linerless platen’s useable life. If the linerless media
continues to jam after cleaning and feeding 1 to 2 meters (3 to 5 feet)
of media, replace the platen.
Note • Never apply cleaning liquids directly to the printer. Do not let
liquid pool on any area of the printer or penetrate the internal circuitry
of the printer.
