General Cautions and Warnings

This page describes general safety and maintenance warnings and cautions for the printer and
are referenced throughout the manual.

Warning - Shock Hazard

The printer should never be operated in a location where it can
get wet. Personal injury could result.

Warning - Static Discharge

The discharge of electrostatic energy that accumulates on the
surface of the human body or other surfaces can damage or
destroy the print head or electronic components used in this
device. DO NOT TOUCH the print head or the electronic
components under the print head assembly.

Caution - Printer Setup & Handling

1)When installing or modifying the printer setup or
configuration, ALWAYS TURN POWER OFF Before

A) Connecting any cables.
B) Performing any cleaning or maintenance operations.
C) Moving the printer.

:

Media Warning

Always use high quality approved labels and tags. If adhesive
backed labels are used that DO NOT lay flat on the backing
liner, the exposed edges may stick to the label guides and
rollers inside the printer, causing the label to peel off from the
liner and jam the printer.

Media Reload Hint

If you should run out of labels while printing, DO NOT turn the
power switch OFF (0) while reloading or data loss may occur.
Theprinter will automaticallyresume printing whena new label
or ribbon roll is loaded.

Print Quality Tip

Print density (darkness) is affected by the heat energy (density
setting) applied and by the print speed. Changing both Print
Speed and Density may be required to achieve the desired
results.

MOVIE

Tag Stock

You must remove the outside length of media
(that is, one, full revolution of labels and any
liner). When youremovethis part ofthemedia,
you remove the oils, dust, and adhesives that
contaminate it. Tape or adhesive holds the
loose end and the outside length of media
becomes contaminated when handled or
stored.

Detach both ends of

the bottom tag

You must avoid dragging adhesive or dirty
mediabetween theprintheadandplaten. Such
an occurrence damages the print head and is
not covered under your warranty. Using clean
media prevents damage and reduces wear on
the print head and platen.
