Built into the Zebra S-Series Printers are test routines to aid the technician in
diagnosing faults.
Power ON Self Test
A Power ON Self Test (POST) is performed each time the printer is turned ON.
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 will turn ON and OFF to insure proper
operation.
At the end of this self test, only the POWER LED will remain lit. If other LEDs
remain lit, refer to Troubleshooting in this manual.
Printer Self Tests
These self tests produce sample labels and provide specific information which
helps determine the operating conditions for the printer.
Each self test is enabled when a front panel key is pressed while the printer’s
AC Power Switch is turned ON. Keep the key pressed until the front panel LEDs
turn ON.
When the Power On Self Test is completed, the selected printer self test will
start automatically.
