10. Maintenance
The XPM 80™ printers require very little maintenance.
Note: Discharge your body's static electric charge by touching a grounded surface before
performing any maintenance procedure. Do not touch the connector pins of the printhead
cable with your bare hands.
Note: Do not touch the surface of the thermal printhead.
(including foreign contamination) to the surface of the printhead substrate should be avoided
to prevent printhead damage.
Cleaning the XPM 80™ Printer
Clean the XPM 80™ whenever it becomes dusty, as paper dust will reduce the friction of the platen
and cause the print quality to deteriorate.
Open the print mechanism by using the Printer Access Control. Remove any paper, if
necessary.
Clean the platen with a special platen cleaning agent and a lint-free cloth. DO NOT use
alcohol to clean the platen because alcohol hardens the platen material.
Gently wipe the surface of the thermal printhead using a cotton pad soaked in
METHANOL to remove dust on the heating elements. DO NOT use sandpaper or other
abrasives.
Dry the XPM 80™ mechanism completely and reload the paper.
Note: Condensation should be avoided. If condensation occurs, do not power the printer until
all condensation has dissipated.
