Preventative Maintenance
Zebra recommends cleaning the printer on
a regular basis using standard Zebra printer
parts and cleaning supplies. Consult your
“User’s Guide” for further details.
• Cleaning — The exterior is cleaned with
a lint-free cloth, and if necessary, a mild
detergent solution or desktop cleaner.
Interior components (printhead, platen roller,
media sensor, peel bar, ribbon and media
paths) are cleaned with alcohol or blown
air to remove any particles.
• Lubrication — All mechanical parts
are self-lubricating and do not require
additional lubrication.
• Print Registration — Media registration
and minimum label length are affected by
media type and width, ribbon type and print
speed. Performance improves as these
factors are optimized. Zebra recommends
always qualifying any application with
thorough testing.
• Printhead Replacement — For optimal
printing quality and proper printer
performance across our product line,
Zebra strongly recommends the use of
genuine Zebra supplies as part of the total
solution. Printers are designed to work
only with genuine Zebra printheads, thus
maximizing safety and print quality.
