Troubleshooting
Test routines are built into the Zebra 110XiIII-Series printers to aid the technician in
diagnosing faults. Some of these tests are enabled by holding a front panel key while
turning the printer On (l).
Power-On Self Test
A Power-On Self Test (POST) is performed each time the printer is turned On (l). 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 3-13.
If the printer is set up for non-continuous media, one or more labels feed out, up to a
maximum length of one label plus 3 in. (76 mm) of additional media.
To initiate the Power-On Self Test, turn the printer On (l) using the power switch located at
the rear of the printer. 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
starts on page 3-2.
