Preventive Maintenance

Extending Battery Life

•Never expose the battery to direct sunlight or tempera- tures over 104° F (40° C).

•Do not charge the battery when the temperature exceeds

113° F (45° C).

•Always use a Zebra charger designed specifically for

Lithium-Ion batteries. Use of any other kind of charger may damage the battery.

•Use the correct media for your printing requirements. An authorized Zebra re-seller can help you determine the op- timum media for your application.

•If you print the same text or graphic on every label, con- sider 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 dis- play backlight only when necessary. Turn it off whenever it is not needed.

•Remove the battery 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 re- charged a finite number of times before it must be re- placed. Always dispose of batteries properly. Refer to Appendix E for more information on battery disposal.

Caution • Do not print while the LI72 Wall Charger is plugged into the unit. Unreliable battery charging can result.
