Preventive Maintenance

Extending Battery Life

•Never expose the battery to direct sunlight or tempera- tures over 104° F (40° 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 optimum media for your application.

•If you print the same text or graphic on every label, consider using a pre-printed label.

•Choose the correct print darkness, and print speed for your media.

•Use software handshaking (XON/XOFF) whenever pos- sible.

•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 when- ever it is not needed.

•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. Always dispose of batteries properly. Refer to Appendix D for more information on battery disposal.

•Don’t print while the Model LI 72 Wall Charger is plugged into the unit. Unreliable battery charging can result.
