I get "printer not responding"

the adapter you need is p/n PCGA-AC16V6

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.

Try unplugging power from the printer and restarting. If this does not work, check the USB cable or the wifi connection to the printer. If this does not work, delete the printer from your computer and add it back. If the computer does not see it, then you know you have a connection probem either USB or wireless

Here is a great site about that problem - http://www.techsupportforum.com/forums/f10/communication-not-available-the-printer-can-not-communicate-with-the-computer-help-198126.html

are you trying to print from the computer that the printer is connected to or from a wireless computer to the printer on a another pc

Have you tried a "wired" connection to a different computer?
If the problem persists, then the printer itself is the problem.

Have you tried a "wireless" connection from a different computer?
This presumes that the wireless-configuration on the printer is correct,
and that the printer is "talking" to your wireless router.

Login to the router's web-interface, and check the status of all "wireless" connections,
to ensure that the printer has a valid wireless connection to the router.

You may need to uninstall your existing Lexmark driver from your computer. Follow the steps in this article on How to Uninstall Lexmark Printers. Reboot your computer when prompted. To reinstall, click this link Lexmark P4350 Drivers to download the driver from the Lexmark website. Hope this helps. Thanks.

First things frist. If the printer is conected with a USB Cable to your computer, try removing and reinserting the usb cable. To make sure that it is properly connected.
You might just have unintentionally got the printer in offline mode. Now follow this steps:
To check if it is offline. 1. Go to devices and printers (7), Printers and Faxes(XP), Printers (Vista) 2. Double click on the printer icon 3. Click the option that says Printer on the upper left corner of the window that pops up.
Th only options that you need checked is the one that says Set as Default Printer. For any other options that has a check mark. Click on them to remove the check mark.
4. Click Start again, on the search box type in services.msc, hit Enter. For XP, CLick Run, and type the same thing and then hit ok. 5. A window should pop up with the list of services for your computer. Look for Print Spooler in that list. 6. Right Click on the Print Spooler and Click Stop. 7. Right Click on the Print Spooler and Click Start.
Restart your computer. Try printing again.

Sometimes this problem occures when you install a later model wireless router.
Try installing the latest Wireless card driver on the XP computer and the LAN card drivers on the other computers except the MAC.

GO TO PRINTER MENU AND CHECK THE JOB IN QUE AND CHANGE FROM OFFLINE IT TURNS TO READY
