Dell 1720 DN- all lights flashing- please advise

It helps SO much when you include the Model number of the printer you are asking about. If it happens to be a Dell 1720 then simply push the tab down located at the top right of the output bin. that Tab sticks open can cause the light to flash.

Hi!

Here's a link for you:

http://support.dell.com/support/edocs/systems/prn1720/en/1720_en/en/index.html

It's not really a download version of the manual, but you can still find all the content via the links on the site.

Hope it helped,

Try unplugging the printer for fifteen minutes or so. If that doesn't do it then it it your main board. Sorry for the bad news.

do a system restore from the time when everything was working fine.
start>programs>accessories>system tools>system restore
download and install dell quickset and flash bios from the support site.

I found out this is caused by the touchpanel on the top.

You can find a junk 1720(dn doesn't matter) and replace the top cover assy. yourself, or you can replace the printer(usually cheaper). Sorry, this is usually terminal for these printers.

The second link was the helpful information. Also, to cut through all of that --

If you need to reset the counter:

1. Remove drum kit with toner

2. Make sure all print jobs are flushed otherwise whatever has been sent and not printed will come spewing out.

3. Hold down CANCEL Button until all lights flash through.

4. Slide the drum kit and toner properly into the Printer.

done.

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.

Thanks

Dell Laser Print 1720 dn Properties window. Click on the last tab called install options. Click the ask printer button. This should update the print driver with the add on drawer.

All flashing lights for the Dell 1700 series (1700, 1710, 1720 including those that have n or dn as part of the model) printers is a service related error. When double pressing the continue button twice quickly, the printer will give a secondary error code, narrowing down the printer part being effected. It is possible to even narrow the error code down even futher by double pressing the continue button and taking note of which combination of lights come on, wether they are steady or blinking. Most generally when this series of printers, when you get all flashing lights, something major is going on with the printer. It could be pointing to the fuser, or main board, etc. You can call dell warranty support and they will help narrow down which part is being effected. Most generally, what is being effected is not cost effective to get fixed if you are no longer under warranty.
