My printer is Lexmark x5650. It prints well, but when i try to scan it starts making knocking noise after few seconds and continues 15 sec. then i get a message on printer's control panel display "unrecoverable scan error". I tried by disconnecting and connecting usb cable, main power plug, but the problem not fixed. Would you plz help me? Thanks. -Shams

Try using the Lexmark Productivity Studio to scan. To access that, on your computer, click on Start > All Programs > Lexmark 5600-6600 Series > Lexmark Productivity Studio.

If it doesn't work, try to uninstall the Lexmark driver and download an updated driver online at support.lexmark.com.

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.

printer wont scan to pc - Lexmark X5650 ALL-IN-ONE PRINTER

The Lexmark X5650 printer requires both the black and color cartridges to be inserted in the printer to continue printing. Both cartridges must have ink in them and not empty.

ok. if its making a grinding noise its the belt slipping. you may not have the print cartridges installed properly. kit could also be the scanner belt that may be slipping. Basically if its not the print cartridges then the scanner is stuffed. Unless you are handy and are prepared to pull thing apart to get to the scanner belt I'd say it has gone to god.

Did you install the full-featured software or just the OS generic driver? If a full-featured software exists for your OS, uninstall the previous driver, unplug the USB cable and install the full software.

Next try a new USB cable and a different port. If you have a USB hub or print server in use, try a direct connection to the computer. (Scanners need bi-directional communication and fail even when the printer works.)

If you can't launch a scan from the all-in-one, try launching it from the computer. (Either the full-software or another scan program (Win7 and Vista let you scan into Paint. Win7 and some versions of Vista have Windows Fax and Scan for those all-in-ones that only get support from Windows generic drivers on those OS's).)

Some of the full-featured software drivers include a monitor that must be running to see if buttons are pressed on the scanner. Check that if this is the case for your all-in-one.

I hope this helps.

(I'm assuming that the printer itself works which means the USB ports aren't disabled for power-savings or security.)

Hello. Try removing all sheets of paper from the printer. Make sure to check in the feeder by peeking inside it. Clear any foreign objects. Open the printer cover, and remove the cartridges. Clear any foreign objects around the cartridge carrier. Close the printer cover without the cartridges. Unplug the printer from the power outlet. Plug the power back after 10-15 seconds. It should power on automatically. When printer asks for the cartridges, load them back in. Close the cover down. Printer will print an alignment page. Just let it finish print the page. When there's no more error, try to make a copy or print from the computer to check. Hope this helps.

Hi,
that sounds more like a mechanical issue. You might want to call Lexmark at 1-800-LEXMARK about the problem. Hope your printer is still within warranty. Hope this helps.
