Power On Self Test
A Power On Self Test (POST) is performed each time the printer is turned ON. During this test, the
front panel lights (LEDs) will turn ON and OFF to ensure proper operation. At the end of this self
test, only the POWER LED will remain lit. Once the Power On Self Test is complete, the media is
advanced to the proper resting position, as determined by the programmed Media Feed setting.
To initiate the Power On Self Test, turn the printer ON using the power switch on the control panel.
The POWER LED will go ON. The other control panel LEDs and the LCD monitor the progress and
indicate the results of the individual tests. All displayed prompts occur in English; however when a
test fails, the prompt will also rotate through the international languages.

1. All lights turn on simultaneously and then turn off in
sequence through the following steps.
