Some of these tests are enabled by pressing a front panel key while turning the printer power
switch ON.

A Power-On Self Test (POST) is performed each time the printer is set to the On (I) position.
This test checks for proper initialization of various electronic circuits and establishes starting
parameters as those stored in the printer’s memory. During this test sequence, the front panel
LEDs turn on and off to ensure proper operation.
At the end of this self test, only the POWER LED remains lit. If other LEDs are also lit, refer to
“Basic Troubleshooting” on page 3-11.
If the printer is set up for non-continuous media, one or more labels feed out.
To initiate the Power-On Self Test, turn the printer ON using the power switch located at the
rear of the printer. The front panel power-on indicator lights. The other front panel LEDs and
the Liquid Crystal Display (LCD) monitor the progress and indicate the results of the self test.
The normal self test sequence is shown on the following page.
