Power-On Self Test
A Power-On Self Test (POST) is performed automatically each time the
printer is turned on. This test checks for proper initialization of various elec-
tronic circuits and establishes starting parameters as those stored in the
printer’s memory. During this test sequence, the front panel lights turn on
and off to ensure proper operation. See “Power-On Self Test Sequence” on
page 30.
Additional Printer Self Tests
These self tests produce sample printouts and provide specific information
which helps determine the operating conditions for the printer.
Each self test is enabled by pressing a specific Front Panel key or combina-
tion of keys while turning the Power Switch on. Keep the key depressed
until the Data light turns off. When the Power-On Self Test is complete, the
selected self test starts automatically.
Notes: When performing self tests, disconnect all data interface cables from the
printer.
When canceling a self test prior to its actual completion, always turn the
printer power off and then back on to reset the printer.
When performing these self tests while in the Peel-Off Mode, you must
remove the labels as they become available.
If your media is not wide enough or long enough, unexpected and/or undes-
ired results may occur. Make sure that your print width is set correctly for
the media you are using before you run any self tests, otherwise the test may
print out on the platen. See page 36 for information on setting the print
width.
