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.
