Printer Prints Slowly Check1 Printer may be printing a large job from another computer. Check2 Make sure the printer is not placed too far away from the wireless router. Place the printer and wireless router 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 printer cannot communicate with the computer over a Wi-Fi due to a wall, place the printer 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. Check3 Make sure wireless signal is strong. Monitor signal status and move printer and wireless router as necessary. Check the signal strength on the LCD. LCD and Operation Panel Note • IJ Network Device Setup Utility allows you to diagnose and repair the network status.
