What you will see
  • If you are unable to print or scan from the All-In-One Center, or
  • You are able to scan using Microsoft's scanner and camera wizard or MS Paint application, or 
  • Print jobs are seen stacking up in your print queue and showing a "Printing" status, or 
  • Communication Not available message with printer and computer...

...Should any of the above statements apply, then your Internet firewall application may be blocking critical printer communication processes that allow the printer to communicate with the printer software.



Recommended Tests or Remedies
  1. Cancel or delete any existing print jobs from the print queue.
  2. Next:
If using the Firewall provided by... Then... And then...
Microsoft Temporarily disable it and try printing again. Click here for a Microsoft article (Windows 8.1) that describes both this procedure. If the printer now prints, you will likely have to create exceptions for your printer's software processes. Click here for an example of this procedure.
Other manufacturers Temporarily disable it and try printing or scanning again. See your firewall application User's Guide. Set firewall all rules/permissions to grant Lexmark-application processes the ability to communicate through the firewall.

NOTE: Security threats are possible when you disable the firewall. You can take some precaution by disconnecting your computer from the wide area network and still retain local network connectivity with the printer.   



IMPORTANT! The location for granting permissions or setting exceptions will vary by the brand of Firewall or Security application. You have to know which processes may be blocked to carry out this procedure.
