Power-On Self Test (POST) sequence
When you turn the printer on, it performs a POST. Check for correct POST
functioning of the base printer by observing the following process:
1.
All operator panel lights on momentarily
2.
Lights then flash on and off sequentially.
3.
After the lights quit flashing, the
light flashes until the fuser comes
up to temperature (5–20 additional seconds, depending on the initial
temperature of the fuser) and then stays on.
4.
If there is a problem in the printer such as a paper jam, the panel lights
indicate the problem. See
“Common primary light patterns” on
page 2-4
for more information.
5.
The printer cycles down into standby mode, and
lights solid.
