Check 4: Cannot Find Machine on Check Printer Settings Screen
During Wireless LAN Setup
Check wireless router configuration and make sure the machine is not
placed too far away from the wireless router.
• Checking wireless router location
After checking the wireless router setting, make sure the machine is not placed far away from the
wireless router.
Place the wireless router and machine where there are no obstacles between them. Wireless
communication between different rooms or floors is generally poor. Wireless communication can be
impeded by building materials containing metal or concrete. If the machine cannot communicate with
the computer over a wireless LAN due to a wall, place the machine and the computer in the same
room.
In addition, if a device like a microwave oven that emits radio waves of the same frequency bandwidth
as a wireless router is nearby, it may cause interference. Place the wireless router as far away from
interference sources as possible.
• Checking wireless router settings
The machine and wireless router should be connected using 2.4 GHz bandwidth. Make sure the
wireless router for the machine's destination is configured to use 2.4 GHz bandwidth.
For more on the wireless router, refer to the instruction manual supplied with the wireless router or
contact its manufacturer.
After taking measures above, click Redetect on the Check Printer Settings screen to redetect the
machine.
If the machine is found, follow the instructions on the screen to continue to set up network communication.
If the machine is not yet found:
If the machine is not yet detected after checking all items, connect the machine to the computer using a
USB cable to set up the network communication.
Select the Set up the network connection via USB check box on the Check Printer Settings screen,
and then click Next.
