A Power-On Self Test (POST) is performed automatically each time the printer is 
turned on.  During this test sequence, the front panel lights and liquid crystal display   
(LCD) monitor the progress of the POST.  If the printer fails any of these tests, the 
word “FAILED” is added to the display.  If this occurs, notify an authorized Zebra 
reseller.

These self tests produce sample printouts and provide specific information that help 
determine the operating conditions for the printer.

Each self test is enabled by pressing a specific front panel key or combination of keys 
while turning the POWER switch on.  Keep the key(s) depressed until the DATA light 
turns off (approximately five seconds).  When the Power-On Self Test is complete, the 
selected self test starts automatically.

NOTE:  When performing self tests, avoid sending a label format to the 
printer.  In the case of a remote host, disconnect all data interface cables from 
the printer.

NOTE:  When canceling a self test prior to its actual completion, always turn 
the printer power off and then back on to reset the printer.

NOTE:  When performing these self tests while in the Peel-off mode, you 
must remove the labels as they become available.

NOTE:  If your media is not wide enough or long enough, unexpected and/or 
undesired 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 roller.  See page 42 for information on setting the 
print width.
