Understanding POST Error Messages
This section tells you how to unders tand and respond to the power- on self-test
(POST) error messages.

Function of POST Error Messag es

The printer fuser takes approximately 5 minutes to warm up if it is cold when
you turn the printer on. While the printer is w ar ming up, it runs a power-on
self-test (POST). The POST checks to see if the printer is working correctly.
As the POST runs, you see status messa ges on the display panel. You do not
have to read these messages unless the POST stops before the test is
finished. Normally, the POST finish es w it hou t problems and you see the
READY message on the display panel.
If the POST does stop before it is finished, the Attention light on the display
panel flashes. Check the display pane l for a message, an error code, or a
blank display. See the following table t o f ind out what to do.
