Dell 1700 laser printer has Low toner and error lights flashing

I was able to reset the drum counter using your instructions and print a test page with the 'Continue' button, so I know that the printer is functioning but my system still tells me that I have an "Unknown Toner Level" when I try to print a document and will not print. Is there a fix for this?

Ya!!! It was very hepfull. Thanks a lot.

Reset the photoconductor (PC) drum counter on the Dell™ 1700(n) printer.
To reset the photoconductor (PC) drum counter, perform the following steps:
1. Turn off the power using the switch on the back of the printer.
2. Open the front door of the printer.
3. Hold the Continue button down, power on the printer, continue to hold down the Continue button until just the Error LED is on solid, then release the Continue button.
4. Close the front door.
The Continue button, Ready/Data, Toner Low, and Load Paper LEDs should all be lit.
5. Wait for the printer to complete its POST process.
This is completed once the printer begins emitting a fan noise and the rollers start, then stop.
6. Press the Cancel button four times slowly until the Toner Low LED is lit.
NOTE: This is the option for resetting the drum counter.
7.
8. Press and hold the Continue button until the LEDs all begin to rapidly cycle up / down in sequence, then release the Continue button.
The Toner Low LED is the only one on.
9. Cycle the power on the printer.
10. When the printer is ready, press the Continue button once to print a settings page.
11. Under the heading Cartridge Information, verify the Photoconductor value is 0K (zero-K).

Leave the printer on. Open the front and hold down the cancel button until all the lights are flashing in sequence. Close the front while still holding the cancel with the lights flashing and then release the cancel button. This should reset it.

Toss it out. That printer is a piece of junk. I have 4 fairly new 1700's and they all just about crapped out.
