I have an Okidata C5150n Color LED/Laser printer that I have had for about 5 years. The printer has worked beautifully for all that time, never had a problem. Today, however, when I powered up the printer I heard the noises liken to those when it goes through its power up routine. I then noticed the front panel lights were not illuminated. I cycled the power and watched more closely. This time I noticed the lights on the front panel came on for about a second then went out. Again I heard what sounded like the power up noises. The lights never came back on and the front panel buttons did nothing. I removed all the components of the printer and searched for anything catastrophic, nothing.
