Third light flashing on the 1720dn dell - Dell 1720dn Laser Printer

SOURCE: Dell 1720dn Error and Toner light on

After replacing the drum unit you have to tell the printer that you've done it(it's not smart enough to figure it out itself). Have the front door open and press and hold the Cancel button on the printer until all lights flash in sequence then let go. Then close door and try.

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.

Did you reset the counter?
After you replace the imaging drum, you should reset the imaging drum's counter. To reset the counter, press and hold the Cancel button until all lights flash in sequence.

I hope this helps.
