Scanning Whenever I want to scan the printer always goes to "Downloading Applications List" And then comes back with "Cannot retrieve applicationList". This does not always happen. But it happens more often than not. What am I doing wrong?

Open the printer/scanner tool menu and select scan and save to computer.

If your pc tels you its downloading application, have a look a your printer drivers, your usb cable connecting your pc to printer and or the data cable inside the scanner might have gone faulty

Try using the Lexmark Printer Home software to scan. To access that, on your computer, click on Start > All Programs > Lexmark > Lexmark Printer Home.

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.

plz install drivers of your printer first to your pc.

I gave gotten it to retrieve the applications list by opening Lexmark Imaging Studio while it was searching, I AM however still unable to scan it connects to my comp I tell it to save as a file and it goes "Requesting Scan" then "Scan Request Failed"

Problem: Lexmark cannot retrieve applications list

I have the Lexmark X3550 with the WiFi option board installed (makes it same as the model X4550) and get the “cannot retrieve applications list” message on one of the five computers connected to my router (Linlsys WRT54G V8) and using wireless printing and scanning. Just like everyone else with a similar Lexmark WiFi printer/scanner, I can print wireless, but cannot get the wireless scanner to work on one of my PCs.

The fix, in my case, was to change the Lexmark network name as follows.

1. Launch Lexmark Imaging Studio.
2. Right-Click on “View or change network settings”.
3. Enter a new network name in the first box shown. (This box contained the correct network name for my PC, but another name was needed to make the scanner work. I simply added “-lex” at the end of the current network name.)
4. Right-Click OK. You should return to the Imaging Studio screen.
5. Close the Lexmark Imaging Studio window. (The tray icon should remain at the screen lower right.)
6. On the printer, press the Scan Mode button.
7. On the printer’s display screen, select the Computer Name that you entered for the new network name. Just use the arrow buttons until the exact name is shown.
8. Press the Check button. The display screen should show “Downloading Applications List”. Within about 10 seconds the message should change to “ *Scan to Computer ”. Wireless scanning should now work.
9.. Press the Start Color or Start Black button. “Requesting Scan” will be shown. After a few seconds scanning will start. The process is a bit slow.
10. After a while you may see an empty small Lexmark window onscreen. Later, the Lexmark Imaging Studio will appear onscreen, then change to show many options and features. An image of the scanned item will appear in a Lexmark window. Save and/or edit the image. Another scan can be done by pressing the printer’s Check button again. Be sure the correct computer name is shown on the printer’s display.

That’s it. A new computer name was the solution. Your PC and printer may require a restart (power off) after changing the “computer name”.

try uninstall it then install again

No its seem to be some software clashed problem! Try to remove your old software and then try to clean registry and then install again then it should work!
