2. Remove Obstacles between the Access Point and the Printer
The wireless signal from your access point will pass through most objects. Most walls,
floors, furniture and other objects will not block the wireless signal. However, there are
materials that are too dense for the signal to pass through. Objects containing metal
and concrete can block the signal, including:
• Cubicle walls
• Ducts
• Window frames
• Poles and interior support columns
• Metal office furniture and cabinets
• Elevators
• Steel doors
• Walls and other structural elements reinforced by rebar
Arrange your printer and access point so that the signal is not blocked by any of these
objects.
3. Remove Sources of Interference
Other types of radio frequencies can cause problems with the wireless signal on your
network. These sources of interference can cause printing issues that seem to come and
go. Some common sources of interference are:
• Cordless phones
• Microwave ovens
• Refrigerators and other appliances
• Bluetooth devices
• Other wireless networks
• Motors
Turn off these potential sources of interference where possible. Avoid using microwaves
and cordless phones when printing over your wireless network.
If another wireless network is operating in the vicinity, change the wireless channel on
the access point.
Do not place your access point on a printer. Printers can also interfere with the wireless
signal.
