Preventive Maintenance
WARNING: To avoid possible personal injury or
damage to the printer, never insert any pointed or sharp
objects into the printer.
Extending Battery Life
•Never expose the battery to direct sunlight or temperatures
over 104∞ F (40∞ C).
• Always use a Zebra charger designed specifically for Li-
thium-Ion batteries. Use of any other kind of charger may
damage the battery.
• Choose the media that is easiest to “burn.” An authorized
Zebra re-seller can help you determine the optimum media
for your application.
• If you print the same text or graphic on every label, consid-
er using a pre-printed label.
• Choose the correct print darkness, and print speed for your
media.
• Use software handshaking (XON/XOFF) whenever possi-
ble.
• Select Tear-Off mode whenever possible (Peel-Off mode
uses more power).
• If your printer has the optional LCD display: Use the display
backlight only when necessary. Turn it off whenever it is not
needed. The LCD backlight consumes a great deal of pow-
er.
• Pull the battery out of the printer if the printer won’t be used
for a day or more and you’re not performing a maintenance
charge.
• Consider purchasing an extra battery.
• Remember that any rechargeable battery will lose its ability
to maintain a charge over time. It can only be recharged a
finite number of times before it must be replaced.
