8. Check8 Make sure that there is no obstruction.

   Wireless communication between different rooms or floors is generally poor. Adjust the location of the devices.

9. Check9 Make sure that the printer is not place as far away from the access point.

   The access point is located indoors within the effective range for wireless communication. Locate the printer within 164 ft. / 50 m from the access point.

10. Check10 Make sure that there is no source of radio wave interference in your vicinity.

    If a device (e.g. microwave oven) using the same frequency bandwidth as the wireless station is placed nearby, the device may cause interference. Place the wireless station as far away from the interference source as possible.

11. Check11 Make sure that the network settings of the computer are correct.

    Make sure that the computer can communicate with the printer and the access point over the wireless LAN.

12. Check12 Make sure that Enable bidirectional support is selected in the Ports sheet of the properties dialog box of the printer driver.

13. Check13 Make sure that the firewall of the security software is disabled.

    If the firewall function of your security software is turned on, a message may appear warning that Canon software is attempting to access the network. If the warning message appears, set the security software to always allow access.

    If using any programs that switch the network environment, check their settings. Some programs will enable a firewall by default.

14. Check14 When using a router, connect the printer and computer to the LAN side (same network segment).

If the problem is not resolved, perform setup with the Setup CD-ROM or perform it according to the instructions on our website.
