Is the power cord plugged
into the wall and the
printer? Is AC and DC
power available?
Verify. See Table 7-3, “No AC Power,” on page 7-9 and Table 7-4,
“No DC Power,” on page 7-10.
Is the power switch set to
on?
Set the switch to the on position. You should hear the switch
toggle. If the Front Right Side Cover has been removed recently,
be sure that the rod leading to the power supply moves as the
rocker switch is toggled.
