CAUSE/SOLUTION
A printer hardware error is detected. Possible printer errors
include malfunction of the Fuser unit, Laser unit, Scanning motor,
or Fan.
Corrective Action: First power off the printer and then turn the
power back on. If the problem continues, contact your NEC dealer
for service or call NEC technical support (see Chapter 10).
During power up, press the Operator panel button until the lights
stop cycling, then release. After that, the green light blinks until
the printer is ready to accept a job.
When you power on the printer all the LEDs light, then cycle
through beginning with the On Line LED. The lights continue to
cycle until initialization is complete. The On Line light will continue
to blink until the printer is warmed up sufficiently to print.
