Printer Diagnostics

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 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 printer 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.

• When cancelling a self test prior to its actual completion, always turn 

the printer 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 or 

undesired results may occur. Ensure 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 

 for 

information on setting the print width.
