    Hi, first of all I would like to thank you for trying to find a solution.

    The Service Tag of my Printer is 108ZTB1. I could not find the part of the site, where I have to put in this number. Could you try please? I´d be very thankful

    The webserver is only included in the 1720dn version with a network card. Unluckily I haven't got that one. :(
    I´ve tried to contact dell, but they haven't answered me yet.

    Need the serial number/Service Tag?

    Curious to know why you want to update the firmware? Unless the firmware update fixes a specific problem you are having, it generally not a good thing to do. Reason being is that if you encounter a problem updating the firmware it can make the printer useless and not work at all.

You need to run the usbflash.exe file that should have come with the fls file. If not you can get it from a number of sources either DELL or Lexmark sites.
The usbflash file will ask for the .fls file when it is run.

However later you say you are trying to resolve a problem with a paper jam being indicated when there is none. If you take the toner and pckit out ...underneath them in the inside of the printer the middle a sensor. Its a tiny plastic bit that sticks up and the paper passes over. If this is stuck or stiff and not will indicate a paper jam permanently. If you cannot reposition it with your fingers or some will need a tech to fix it.

One other thing to check is the flag where the paper comes out. If you wiggle this and the error goes away then the flag is bent. You can try and bendit back into shape......otherwise it will need a tech to fix it.

The .fls file (firmware file) can be updated via the embedded web server of the printer.

I tried to download the firmware update your looking at. It appears that something is wrong with the download package Dell has on it website. Normally there would be an application included in the download to update the firmware or instructions on how to do it from the web-based configuration wizzard of the printer.

Under the "Fixes and Enhancements" section of the download, it lists this file as the "Intial Relase" which to me means it is the version of firmware that shipped with your printer. I doubt using it will fix any issue you are having. If you still want to proceed, here it the steps I've taken that you'll have to take:

I tried to contact Dell to get the download fixed, but they wont talk to me without the
serial number/Service Tag of the printer or account number that I requested from you in the above clarification request. The instruction for the download say that you are supposed to be downloading and "exe' file, but the link is downloading the "R156881.fls" file you are getting.

You could alternatively contact Dell yourself to resolve the download issue. Dell contact page:

    Regretfully it turns out that I can't do it for you b\c then they would have your printer registered to me which would probably cause you problems in the future. You have to fill out the Customer Service Email Form (the link I gave you) and put in the service tage info. there. About 3/4 down the page there is a place for it. Hope this helps.

    It's not possible for the end user to update the firmware on the non-network version (1720) of this printer. You'd have to send it in to Dell for repair. Sorry.

I have the problem with the paper jam error, though there isn´t any paper jam. I´ve read in an other topic, that the firmware update should solve this.

Hi, and thanks for your time. I have a problem with a ZyXEL G570S (NOT version 2) and a Dell 1720 (1397 minicard)as follows: While everything works perfectly when using the WPA mode, the association is...

There are several different types of both WPA and WPA2. If you are using a "Pre-Shared Key", make sure you are selecting "WPA2 Personal". If you use any other type of WPA2, it is going to begin looking for certificates installed on your mobile device/PC, and also ask for a RADIUS/AAA (802.1x) authentication server, which I'm assuming you don't want.

Have you tried upgrading the firmware or changing the WPA2-PSK settings on the ZyXEL?

This is a common issue, do you have a thumb drive or aka flash usb drive? If you do use your computer to d/l the firmwareupdate
HERE then load the firware update from the thumb drive onto the ps3 via one of the usb ports on it, and hopefully this will fix your issue.

Hi Tom,
The Inspiron 1720 &1721 series was released more than a year ago and is no longer available new, only refurbished. The comparbable machines currently on the market is the Inspiron 1525 & 1526 series. The 1525 &1526 series are comparable in price and specs, and the specs are a little better as far as graphics and sound cards. The 1730 series is still available, but it has a price of approx $2500. Hope this helps. If you have any more questions feel free to ask.
