My printer which is an lexmark x4650 just stopped working. it says its not installed what do i do.

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. 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 print again once the computer fully recognizes the USB connection.

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

1. Disconnect the printer from your computer.

2. Rebrick (pull out power supply, black box where the power cord is plugged in at the back of the printer, and put it back after 30 seconds).

2. On your computer, go to Control Panel > Printers and Faxes.

3. Delete the Lexmark print object.

4. Reboot your pc.

5. When your pc turns on, reconnect the printer.

6. Wait until your pc 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, then try to print a document again to verify that the problem is fixed.

You may also try to update your printer driver by visiting the Lexmark website at http://bit.ly/iofMNC. Select your operating system, download and execute the file.
