Solution

What you will see

When attempting to print, you receive a Communication Not Available or Document Failed to Print error message.

Initial Steps

If you receive this warning, try the following steps first, before the topics below:

On the Printer: 
  1. Turn off the printer or all-in-one, and unplug it.
  2. Wait 30 seconds.
  3. Plug the printer back in and power it on.

On the PC:
  1. Save your work, and reboot the machine.

On the Router and/or modem (if printing wirelessly):
  1. Unplug the router and modem
  2. Wait 30 seconds.
  3. Plug in the modem, and wait for it to come to a ready state, then
  4. Plug in the router.

At this point, try printing again.  These steps help fix a number of communication issues between the host (PC) and the client (the printer/all-in-one).
If these did not fix your issue, please continue reading for other solutions.

Topic 1: Wireless Signal Strength Issue

Variables affecting wireless signal strength that may impact the ability to print include:
  • Distance between wireless router/access point and MarkNet print server.
  • Obstructions causing decreased amplitude in signal strength. See Topic 3.
  • Other electronic devices and neighboring wireless networks which emit radio frequency (RF), e.g., microwaves, cordless phones, and baby monitors.
  • Placement of print server (e.g., behind or underneath desk furniture).

What to do:
  1. Print the network settings page and observe the Bitrate value. Lower values indicate a weaker signal, resulting in a greater likelihood of print server failure or a reduction in performance.
    Data Rate Selection Values:
    802.11b 802.11g
    1,2,5.5,11 Mbps6,9, 12,15,24,36,48,54 Mbps

  2. Reposition the access point.
  3. Reposition the print server antenna.
  4. Temporarily turn off other devices that emit RF.
  5. Adjust access point antennas. 
  6. Consider the purchase of high-gain antennas for the router.
  7. Consider the purchase of a wireless repeater or range extender.
  8. Reposition possible obstructions.
  9. Find out if the router supports a radio power throttling and if a more powerful radio setting is available.
  10. See Topic 3 for additional suggestions.   

Topic 2: Printer Status: Not Connected

The Status value on the network settings page indicates Not ConnectedClick here for an article describing the wireless trouble codes displayed at the bottom of the network settings page.  
Explanation:
The print server is not communicating on the network.
What to do:
  1. Check the Wi-Fi indicator light status.  

    • If it is , the print server is not associating with the wireless router's AP, or it is in the middle of negotiating with the AP. Wait for a moment to see if the light turns .
      HINT: You may have to run the Wireless Configuration Utility or Wireless Setup Assistant (Macintosh) to associate with the wireless router/AP again.
    • If it is , and you own a Draft-N router, make sure that router has not been switched over to N-only mode operating in the 5GHz band. See router documentation or embedded web server for more information.   
    • If , you are associating with the access point, but it may not be your access point, or you may have a problem obtaining an IP address, or you may have a network problem.
      HINT: Check to see if the router's DHCP server is turned on. This can result in a Connected status without IP parameters being assigned or an Auto IP address of 169.254.#.#. 
    • If , the wireless network adapter may be the problem. Make sure the printer is turned on.   
  2. Compare and contrast IP parameters (address, netmask, and gateway) on the printer Network Settings Page with those on the host computer and wireless router. (Click here for instructions on obtaining computer IP parameters.) 
  3. Make sure you can ping the router's IP address or the IP gateway.
  4. Make sure other wireless clients can access the network. This does not include computers connected to the router with an ethernet cable.  

Topic 3: Multipath or RF Interference Issue

All forms of multipath and RF interference can affect the success of a wireless print request and may result in a  Wi-Fi indicator light status. 
Examples of multipath obstructions:
  1. Reflection - e.g., the earth's surface, buildings, walls, mirrors, shiny metal surfaces
  2. Refraction - e.g., cold air, a glass pane
  3. Scattering - e.g., any rough surface that causes multiple reflections or scattering for RF waves.
  4. RF Shadow - e.g., space behind point or points of diffraction that are causing dead space. The print server will not work in these areas.
  5. Diffraction - e.g., the bending of RF waves around an obstruction such as a door.
  6. Absorption - e.g., air, water, plants, animals, concrete
    If additional explanations of these terms are needed, click here for a Glossary of Wireless Terms. See below for an illustration.

RF interference examples:
  1. Microwave ovens
  2. 2.4GHz spread spectrum cordless phones
  3. Baby monitors
  4. Sunlight
  5. Elevators
  6. Neighboring wireless networks

What to do: 

  1. Follow the suggestions in Topic 1: Wireless Signal Strength

  2. Change the subchannel on your cordless phone if this feature is available. Alternatively, consider the purchase of a 5GHz+ range phone. Consult the Phone Owner's Guide for more information.

  3. Change the channel on the wireless router/AP. 

  4. Consider the replacement of any device that creates all-band interference, such as microwave ovens. 

  5. Alter environmental conditions such as bright sunlight.

  6. Reduce radio power in congested areas if applicable and only if the router has this throttling feature.    

Topic 4: Restricted Server List

This embedded web server feature prevents client IP addresses that are entered in the restricted server address list from printing or accessing the print server's web page. If you can ping the print server IP address but cannot print or access the embedded web server, this may be the problem.  
What to do: 
Reset the printer's network settings and reconfigure the printer using the Wireless Configuration Utility or Wireless Setup Assistant (Macintosh).    

Topic 5: Other Issues

Other possible causes of why a print job may not print include:

  • -USB connection problem if the printer is locally attached to the computer.  

  • -Workplace VPNs (Virtual Private Networks) preventing communication. Check with workplace to inquire about VPN tunneling.

  • -MAC filtering activated on router set to allow or disallow certain WLAN connections or MAC addresses. See back of printer for MAC(UAA) address identification.     

  • -Document formatting.

  • -Driver settings.

  • -Application-specific issues relating to the application's Printer Setup

WLAN - Wireless Local Area Network
MAC(UAA) - Media Access Control or Universally Administered Address which is a individually unique hardware address found on all network adapters.

Topic 6: Last Resort Solution

If you have tried all of the above suggestions to no avail, reboot your computer and try printing again.
If the issue persists, it is recommended that you try to reset the printer's network adapter and reconfigure the printer using the Wireless Configuration Utility or Wireless Setup Assistant (Macintosh).
NOTE: You will need to connect the print server via USB cable to the client or host computer, and you will need to know the network name (SSID), encryption method, and security/network key or passphrase.
