There is a patch that you can download and run to resolve this issue.
Step 1:
Download the following patch: http://swdownloads.lexmark.com/Patches/3500-4500/3500-4500.exe


  1. To start the process, double-click on the downloaded file and follow the on-screen instructions to continue.

  2. Reboot the PC.

  3. Unplug the power adapter from the back of the printer.

  4. Plug it back in after 30 seconds.

  5. Try to scan again.
    If the problem still exists, follow Step 2 below.

Step 2:
Download the following patch: http://swdownloads.lexmark.com/Patches/3500-4500/3500-4500wifiethernetpatch.exe


  1. Double-click on the downloaded file and follow the on-screen instructions to continue.

  2. Reboot the PC.

  3. Unplug the power adapter from the back of the printer.

  4. Plug it back in after 30 seconds.

  5. Try to scan again.

If the problem is still the same

1.Get the printer ip address of the printer (ex: 192.168.1.10)
-press settings on the printer panel.. go to network setup.. View TCP / IP, open a browser (IE or mozilla) and type in the printer ip address
-you will see the printer page and then go to configuration.. choose scan to network host
-delete all the computer name listed

2. Go to start, all program.. choose Lexmark 3500-4500 series and choose Lexmark Solution Center
-go to Advanced, click on networking and then click on Change PC name or PIN
--rename the PC name and then click on Ok

3. Turn off the printer, unplug it for 10 secs

4. Try to scan, it should work

if it's still the same you need to uninstall the printer driver and download the updated driver in Lexmark.com

-reinstall it using the downloaded driver

GOODLUCK!!!

I have the problem every 6 months, I spend two days to find the solution and this repeats again and again. Yesterday what I did was:

1. Connected to printers web page. To find what IP it took, I looked at the DHCP table in my wireless router where the printer is connected. May be a menu in printer also shows this. Then I removed all the PC's that were previously connected to the printer. I forgot what menu it was in but it should be easy to find out.

2. The above didn't solve the problem. I uninstalled Lexmark Imaging Studio, got the latest version from lexmark.com and installed. Opened it and chose, "The printer is already installed, I just want to connect my printer to it" or along these lines. Then scanning worked. Also start the scanning from the printer by pressing the scan button and then choosing "Computer" instead of file, pdf, etc.

Impact s305 printer won't scan. it's stuck on "downloading application list"


Try using the Lexmark Printer Home when scanning. If you have a PC, to access it click on Start > All Programs > Lexmark > Printer Home. You can scan to a .jpeg, PDF or .doc.

If you're scanning from the control panel of your printer and you're getting an error message, "Cannot Retrieve Application List", most probably your firewall is blocking your printer from downloading the applications. You might want to add the Lexmark files in the exception of your firewall. Click on the link on how to add exceptions to your firewall.

If you're trying to scan to email (email client), try to check this link: http://bit.ly/k0w0Hp

HI,

You can try out these two options one by one to fix it up:

A)
1 Unplug the printer.
2. Uninstall the drivers.
3. Reboot the machine.
4. Go to the lexmark site and download the drivers.
5. Install the new drivers.

B)You will get the "CANNOT RETRIEVE APPLICATION LIST" if your pc blocks the communication from the printer. This can be configured in your personal firewall. This can be Windows Firewall (found in Control Panel, Security Center), Symantec Client Firewall or similar. Depending on the configuration of this firewall you might or might not get pop-up messages from the firewall during installation. These pop-ups will allow you to permanently allow for this incoming communication. But your firewall might be set not to let you decide anything which will typically mean that the calls will be blocked out. This will often be the case if you have a company laptop configured by the company IT dept. You might then have to ask an admin to add exceptions the applications used by Lexmark as the configuration might not be open for you to change.

I think this is the complete list of applications:

Job Status Window Interface: C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\W32X86\3\lxdijswx.exe
Lexmark Communications System: C:\WINDOWS\SYSTEM32\lxdicoms.exe
Lexmark Connect Time Executable: C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\W32X86\3\lxditime.exe
Lexmark Device Monitor: C:\Program Files\Lexmark 3500-4500 Series\lxdiamon.exe
Lexmark Imaging Studio: C:\Program Files\Lexmark 3500-4500 Series\App4R.exe
Printer Communication System: C:\WINDOWS\SYSTEM32\lxdicfg.exe
Printer Status Window Interface: C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\W32X86\3\lxdipswx.exe

Goodluck,

Can't get my 4650 to scan


Hi,
Try the following link http://bit.ly/aLz1xL. You will find specific instructions on how to reset your device and fix the retrieve app list error. Another option is to completely remove the printer and the Lexmark software and then restart the PC, download the driver from the Lexmark.com website and install it, that has helped me before resolve this problem.

Device monitor application problem


Make sure that the Lexmark Imaging Studio program is running. This was installed when you set up your printer.
If you see the multi-colored icon in your task bar for Lexmark Imaging Studio then try pressing the scan mode button twice. You should be able to scan then.

Device monitor application problem


Ok, folk, I have solved this same issue with my Lexmark X4530 and running Vista Ultimate 32 bit. It turned out to be a Windows Firewall issue. I could have just turned off my firewall, but I opted to keep it one and just EXCLUDE all four running processes that the driver loads. Here are the four programs I excluded on my firewall:

C:\Program Files\Lexmark 3500-4500 Series\lxdiamon.exe
C:\Windows\System32\lxdicoms.exe
C:\Program Files\Lexmark 3500-4500 Series\lxdimon.exe
C:\Windows\System32\spool\drivers\w32x86\3\lxdiserv.exe

The above files may be in different locations than what I have listed, especially the last one. The best way to find where these files are running from is to right click on your task bar and choose Task Manager. Click on the Processes tab and look for all the processes running that start with lx....
Righ click on each of those processes and choose Properties. It will display the path the file is located at. In your Windows Firewall, go to the Exclusions tab and then Add Program. Click on the Browse button and navigate to that file and select it and click on OK. Do that for all four processes.

After I excluded all of those files, the printer works exactly like it is supposed to!

Enjoy!
