Check the cable. Check the settings here. See the general troubleshooting section of this article. Here's a link (and here) to many typical error messages for your printer, though I can't reference your "waiting for PC" message. Troubleshoot the network here., and print a network configuration page to check for errors here.
Hopefully something there will strike a chord.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

When i scan to computer it cannot download the application


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 (if USB connected). Then try to print again once the computer fully recognizes the USB connection or when the WiFi light on the printer turns solid green (if WiFi connected.).


If that doesn't help, try the steps below:

  1. Disconnect the USB cable connecting the printer from your computer.
  2. On your computer, go to Control Panel > Printers and Faxes.
  3. Delete the Lexmark print object.
  4. Reboot computer.
  5. Re-brick your printer by pulling out the power supply - black box where the power cord is plugged into on the back of the printer, and re-plug after 30 seconds.
  6. When the printer turns on, reconnect it to the computer.
  7. Wait until your computer fully recognizes the USB connection. To check, go to Control Panel > Printers and Faxes. If you see a new Lexmark print object in the list, try to print a document to verify that the problem is fixed.

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.
