Post (Power On Self Test) - Xerox Phaser 8400 Service Manual

POST (Power On Self Test)

When these tests begin the front panel has been initialized. In most cases, if an error
occurs, a text message is displayed on the front panel along with an LED blink code
flashing on all three LEDs (front panel LED, PS LED and PE LED). The LED blink
codes are: Short Blink = 1, Long Blink = 5. Both rear panel LED's and the front panel
LED all blink together for the 8400 POST messages.
