Document ID:SO3908
 
  Properties  

Problem

Cannot print; Unable to print with green ready; Green Wi-Fi light not printing; Printer cannot communicate with computer; Communication not available; Port missing; Cannot find created port; Unable to find port; power saver not communicating

Environment

Lexmark 1400 series USB port; Microsoft Windows Vista; Microsoft Windows XP Professional x64 Edition; Microsoft Windows XP; Microsoft Windows 2000; BiDi is turned off, or driver is pointing to the wrong port, or the printer is not configured to the correct access point

Solution

What you will see

The W-ifi indicator light is green  ; however, when you try to print you receive one of two possible messages indicating a communication problem.  This can affect any '07 wireless printer.   
Example 1


Example 2
 

Scenarios

Possible ProblemExplanation(s):Possible Solutions:

1. Printer successfully associates with router/access point, but IP address lease from router never took place.
The printer is communicating with the router, but not the network.  A green light on the printer means that it is only communicating with the router.  It is not an indication of successful communication with the network. 
 

  • -Print Network Settings page and verify the IP address.

        How to print settings page links:

    • -Z1400 & Z1500 Series Network Settings page, click here.

    • -X3500 - 4500 Series Network Settings page, click here.

    • -X4800 -7500 Series Network Settings page, click here.

    • -X6500 Series Network Setting page, click here.

    • -X9350 Network Settings page, click here
       

  • -If no IP address exists, verify DHCP on the page says ON.

  • -Check router settings via router web page to verify that DHCP Server/Enable is turned ON.   NOTE: Consult router documentation for this step.

  • -If IP address exists, try to ping the IP.  Click here for instructions.

  • -If ping is successful, verify that the IP Gateway address on the Network Settings page is equal to the router's IP address.  NOTE:  This is the IP address used to access the router's web page.

  • -ping the router IP address/printer's Gateway address.

  • -Verify that the computer is communicating over the network and try to access the internet.

  • -Verify that you are not using a virtual private network (VPN). VPNs prevent network access to local (LAN) networks and are often used for secure connections to the workplace. 

  • -Follow the remaining suggestions below.    
  2.  Printer successfully associates (green light) with router/access point, but IP address lease from router never took place because of a time delay with the DHCP server.
NOTE:  The router acts as the DHCP server.  (The DHCP server is the component of the router that hands out IP addresses based on newly discovered network devices. ) 
The printer requests an IP address from the router during installation of the product, but for various reasons, the router's transmittal of the leased IP address never hits the printer on time.  

  • -Print Network Settings page.  See above links.

  • -If no IP address exists, verify DHCP on the page says ON.

  • -Check router settings via router web page to verify that DHCP server is enabled.

  • -If DHCP server is enabled, run the Wireless Setup Utility.  Check link below.

  • -Follow the remaining suggestions below.
  3.  Printer is connected to the network, but not your network.  Congested areas, and areas with several routers/access points can cause this strange occurrence.

  • -Multiple routers or access points can cause the printer to associate with a neighboring router instead of your own.

  • -This is caused by selecting the wrong SSID or network name during the installation of the product.  This usually occurs when no security settings are applied to the router, and multiple similar branded routers are in the vicinity. 
    Recommendation:  If you did not initially change this value when setting up your wireless network, it is highly recommended that you change the default SSID of the router to prevent this from occurring again.  WARNING! You will have to reconfigure your client computer with the same SSID value and security settings to re-associate with the router.     


  • -Print the Network Settings page and take note of the IP address. 

  • -Open the router's web page and verify that your printer IP address is within the DHCP IP address range displayed for the DHCP server.  NOTE:  Refer to router documentation for this step.

  • -Run the Wireless Setup Utility found under the Lexmark Program group. Be careful when selecting the appropriate network (name) if multiple SSIDs with the same name appear in the list of 'other' networks.  HINT: Check for the strongest signal, but be careful, another router in the vicinity may have a stronger signal than your own!

  • -If using the default factory router SSID, it is recommended that you change this value.  Lexmark is not responsible for this change, and if you need assistance, please contact the router manufacturer.  NOTE:  You will have to reconfigure your remote wireless client PC to allow the remote workstation to communicate with the new SSID.

  • -Follow the remaining suggestions below.    
  4.  If you switch to a wired (USB) connection, the light will remain green.Printer was originally configured successfully for wireless, but you needed a USB connection.  The indicator light will not change to the expected solid orange state.  

  • -Verify selected port.  See 'Other Possible Solutions' below.

  • -See 'Indicator Light' article.  Click here.
 

Other Possible Solutions

Procedure:  Change to Correct Port
This issue is corrected by changing your selected port under Properties > Ports back to the original network port

  1. XP Mode end users:  Click Start > Printers and Faxes.
    XP Classic Mode end users: Click Start > Settings > Printer and Faxes.
    Windows Vista end users: Select Windows logo start > Control Panel > Hardware & Sound > Printers.
  2. Right-click on the printer object, and select Properties from the drop-down menu.
  3. Click on the Ports tab.
  4. Scroll down the list and look for the correct port.  NOTE: The printer name will be displayed and the last six digits of the printer's UAA address will be listed. 
  5. Place a checkmark next to the correct port, and click Apply.
  6. Click OK

Procedure:  Enable Bidirectional Communication

This fix is recommended in the Error dialog box. The steps are as follows:


  1. XP users: Click Start > Printers and Faxes.
    XP Classic Mode users: Click Start > Settings > Printer and Faxes.
    Windows Vista users: Select Windows logo start > Control Panel > Hardware & Sound > Printers.
  2. Right-click on the printer object, and select Properties from the drop-down menu.
  3. Click on the Ports tab.

Other Considerations

Other communication issues can exist, including the following:
  • -Port was deleted, or never created.  Run Wireless Setup Utility.  Click here for instructions.
    NOTE:  A reset of the printer's network settings will probably not be necessary; however, you will need your original installation cable and to verify that the computer is communicating with the access point. 
  • -Distance or signal interference.  (Click here to check signal strength.)  Move the printer or remove obstructions. 
    NOTE: This is the QUALITY setting on the network settings page. 
  • -The printer is connected via USB, but the driver is still pointing to a network port, and the printer's wireless network adaptor is still communicating with the router/access point.  
  • -Firewall issues involving third party software manufacturers.  Click here for related articles.  

Still Need Help? 

Please contact Lexmark Technical Support for additional assistance.  NOTE:  When calling for support, you will need to know your printer model type and serial number.
Please call from near the printer in case the technician asks you to perform a task involving the printer.
