Printing Is Slow
Check1
Machine may be printing or scanning a large job from another computer.
Check2
Monitor signal status and move machine and wireless router as necessary.
• For Windows:
Monitoring Wireless Network Status
• For Mac OS:
Monitoring Wireless Network Status
Make sure there are no obstacles between the wireless router and the machine. 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.
Check3
Make sure there is no source of radio wave interference nearby.
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.
