Printer Diagnostics
Self tests give information about the condition of the printer. The most commonly used are the
Power-On and the CANCEL self tests.
Power-On Self Test
The Power-On Self Test (POST) is performed automatically each time the printer is turned on.
During either test sequence, the front panel LEDs light up and the LCD monitors the progress
of the POST. If the printer fails any of these tests,
FAILED shows on the LCD. If this occurs,
notify an authorized Zebra reseller.
Additional Printer Self Tests
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 On (I). Keep the key(s) depressed until the DATA light turns off. When the
POST is complete, the selected self test starts automatically.
Caution • Be sure that the print width is set to match the label width you are using before
running any self tests. If the labels are not wide enough, the test may print on the platen
roller and damage it.
Note • When performing a self test, do not send a label format to the printer. For remote hosts,
disconnect all data interface cables from the printer. For printers in Peel-Off Mode, remove the
labels as they come out of the printer.
