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 (

). Press the key(s) until the DATA light turns off (approximately five 

seconds). When the Power-On Self Test is complete, the selected self test starts automatically.

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.

Keep the following in mind while performing self tests:

• 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 that your print width is set correctly for the media you are using before you 
run any self tests, otherwise the test may print on the platen roller. See 

 for information on setting the print width.
