We have had this printer for less than a year. Our power went out and when it came back on all of the LED lights were flashing. We turned the printer off and unplugged it as well. After waiting a short period of time, we plugged it back it and turned it on and all the LED lights were still flashing. I believe this means that a "service call" is needed, but I wanted to know if there is another solution.

I just chatted with Dell support about this since I have the same problem of the grinding noise on my C1760NW Dell printer. I have it plugged into an APC backup battery which acts like surge protector (unless power goes out then battery kicks in). He said the printer needs more power and that surge protectors and battery backups are not good for this printer since they restrict the power which sends less power to the motor and fuser than what it was designed for. So with less power from the APC backup/surge protector, the motor moves very slow and may not fuser the toner to the page correctly and can cause permanent damage over time. So I plugged into the wall directly instead and the grinding noise went away immediately even when printing 10-15 pages right after plugging into wall, but then the noise came back when I printed a bigger job. So for now I'm letting it cool down for a couple hours and crossing my fingers that the damage is not permanent. So... answer is plug it into the wall directly for maximum power and hope that your printer is not permanently damaged. By the well, Dell support chat was awesome.
You can remove the top of the printer to remove and clean the pad or reset the printer and continue without cleaning.
These are the instructions which worked for me on my Canon pixma ip470 and has work on many other Canon models:
1) Close the print head cover, and turn off the printer. While pressing the Resume/Cancel button, press the Power button. (Do not release the buttons. The LED lights in green to indicate that a function is selectable.)
2) While holding the Power button, release the Resume/Cancel button. (Do not release the Power button.)
3) While holding the Power button, press the Resume/Cancel button three times, and then release the Power and Resume/Cancel buttons. (Each time the Resume/Cancel button is pressed, the LED lights alternately in either orange or green, starting with orange.) During initialization, the LED blinks in green.
4) When the LED stops blinking and lights in green, press the Resume/Cancel button the 4 times. (Each time the Resume/Cancel button is pressed, the LED lights alternately in either orange or green, starting with orange.)
5) Press the Power button. The LED lights in green, and the selected function is performed. (When the operation completes, the printer returns to the menu selection mode automatically.)
That series of lights indicates a main circuit board failure. You will need a shop to replace the main logic PCB. Could be caused by anything, static shock, bad input power from power strip or power failure, just plain CPU failure. If it's under warranty, 1 year since purchase, you need a Brother service center, out of warranty a new printer would cost less than repair.
Turn off the power using the switch on the back of the printer. Open the front door of the printer. Hold Continue button down, power on the printer, and continue to holding Continue down until the LEDs begin to flash. When the LEDs start to flash, release Continue button. The LEDs will continue flashing until only Error LED will be lit. Close the front door. Continue, Ready/Data, Toner Low and Load Paper LEDs should be lit. Wait till the printer completes the POST process. POST is complete when fan noise and rollers stops. After POST wait for 5 seconds Press Cancel button 4 times slowly until the Toner Low LED is lit. This is the procedure resetting the counter. Press and hold Continue until all LEDs begin to cycle in sequence, then release Continue. Now only the Toner Low LED will be lit. Cycle the power of the printer: Remove the power cable - Wait for 5 seconds - Plug the power cable back to the printer - Power the Printer on.
