Check toner cartridge

The error 200.16 on a Lexmark X644E indicates that the main drive motor is not working due to high mechanical load due to paper jam or bind. The recommended actions are:

- Make sure paper path is clear.
- Check motor to system card connections.
- Replace transport motor.

I suggest you contact our Technical Support Hotline on 1-800-539-6275.

2 options:

1 - Turn off the machine and unplug the power cord leave it unplugged for 10 minutes turn it back on.
"probably not going to resolve it" - T

2- you will need to replace the system board / formatter. this is the board where you plug in the usb/ phone line/ network cable.
"This should definitely take care of it based on my experience with this machine."

I have Lexmark x644 when I turn on the printer only 5 hear repeated sounds

Check this link to the Lexmark website and I hope it's just caused by a loose cable connection. Just follow the instructions carefully. But if problem is not resolved, it may require service. If that's the case, I strongly advise you to contact Lexmark Technical Support for further assistance. Hope I can assist you more on this.

The text on the printer's display shows up backwards, upside down, and when you scroll thru it, things get all cluttered. The printer operates just fine, its just impossible to scroll thru the menus on...

If your 6360 has a blank display, garbled characters, inverted, upside down, or backwards display the control panel is bad and must be replaced.
Here's a video to replace it. It's very easy and takes about a minute.

Paper jam

Hey Guys, I had the same exact problem you all did so i did some thinking and finally i gave up and shook the **** out of it and guess what? There was a birthday candle in the paper feeder. Try turning it upside down and shaking it, if theres anything obstructing the papers path, thats whys its been jamming ^.^

Lexmark x644e LCD Display Upside Down(Inverted)

Hello there,

I've seen this before. The X64X series with this inverted display seems to work fine (printing,scanning,faxing..) the reason for this is still unknown. But I've got it fixed twice by resetting the NVRAM on this MFP. If you are unsure of how to reset NVRAM, please follow the instructions below:

1.Power off the MFP
2. Hold down the 6, 7 and 8 buttons down and turn the MFP On.
3. Please hold down the buttons till it reads resetting factory defaults and then release the buttons. The MFP should now come back to ready status.

Please check out if this solves the issue, If not the machine would need a hardware service.

Merry Christmas!
