I also frequently have this problem with my C6200, definitely the first and last time I buy anything from HP.

Anyways, onto you're problem: I've always found what fixes this is to simply turn your printer off and then back on. I also noticed that whenever you turn off or reset or log off your computer the printer can never locate the computer to scan to. I still haven't found that fix, but what I told you about turning the printer on and off should fix your problem.

I cant get my 4650 to scan it keeps saying downloading application list but it never does anything
If you are scanning documents to edit or save as PDF file, you will need to install the OCR scan software on your computer. The Lexmark OCR scan software is available only on the installation disc that came with your printer. If you lost the disc, please contact Lexmark Technical Support Center to request for one.
If scanning from your printer to your computer was working previously, then it could be just a slight communication problem. A quick fix for most communication errors can be achieved by resetting the printer and/or rebooting the PC. Simply disconnect the printer from your computer (if USB connected) > reboot your pc > unplug and re-plug the printer into the power source to reset it. When the printer turns on, reconnect it to your computer. Then try to scan again once the computer fully recognizes the USB connection (if USB connected). If printer is connected wireless, wait until the WiFi light on the printer turns on solid green before trying to scan a document.

Am trying to scan a document but it keeps saying
You can go to lexmark.com and download the software package for your machine. It won't scan unless it's connected to your computer and the scan software is running, some Lexmarks won't even copy without the software running in your computer.

I finally got a solution to my problem, which is the same as this one. When trying to scan via USB, you have to make sure the unit is set to USB. On the top panel just above the LCD display, is 3 buttons, Copy, Fax, Scan. Hit the SCAN button, till the display says USB SCANNING. Then try to scan again. Good luck!

You must give scan commands from within HP Device Manager.  Try this, it should be fine.
