Cleaning
CAUTION.- Use only the cleaning agents indicated.
Zebra Technologies Corporation will not be responsible
for damage caused by any other cleaning materials
used on this printer.
Never use any sharp objects on the printer mechanism
as they could damage the print head and platen. Clean
the printer with either the cleaning pen supplied with the
printer or a cotton swab saturated with alcohol.
Use the supplied cleaning pen or 70%

clean the print elements from end to end
(the print elements are located in the thin
gray line on the printhead).
If print quality has not improved after
performing this procedure, try cleaning
the printhead with a Cleaning Pad. This
specially prepared material removes
contamination buildup without damaging
the printhead. Refer to Appendix C for
more information.
