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 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 rest position as determined by the programmed media feed set- ting. Continuous media is assumed to be at the proper rest position.
