When attempting to print in a wireless LAN environment, the message Printer not responding may appear. There are several possible causes for this message.

Refer to the following list of recommendations then click on the link to open the article and resolve your issue.

  • The computer and access point (or wireless router) have lost connection. Restart the computer and then attempt to print again.
     
  • The printer's signal strength is low due to its distance from the access point (or wireless router).  Move the printer closer to the access point (or wireless router). To check signal strength, print out the network settings and check the listing for signal strength, the higher the percentage, the stronger the signal.
     
  • The access point (or wireless router) and wireless printer may not be communicating. Power off and back on the access point and printer to restore communication.
     
  • A firewall on your computer may be blocking ports needed for communication with your printer.  Configure your firewall to allow communication with the ports needed for network communication with the printer.  Refer to the documentation for your firewall for information on how to configure the firewall.
     
  • The Canon wireless printer will detect nearby access points. If an incorrect access point was inadvertently selected, you will be able to select the correct one. Confirm the network name matches the one selected on the printer and the one on the computer.
