How can I improve wireless signal strength?
A common reason wireless printers fail to communicate over a network is poor wireless signal quality. If the signal
is too weak, too distorted, or blocked by an object, it cannot carry information between the access point and the
printer. To determine if the printer is receiving a strong signal from the access point, print a network setup page. The
Quality field indicates the relative strength of the wireless signal the printer is receiving. Drops in signal strength can
be intermittent, however, and although the signal quality appears high, it may drop during certain conditions.
If you think signal strength is a problem between your access point and the printer, try one or more of the following:
Notes:
• For ad hoc networks, adjust the computer where the access point is indicated.
• Ad hoc networks have a much shorter range than infrastructure networks. Try moving the printer closer to the
computer if they seem to have trouble communicating.
MOVE THE PRINTER CLOSER TO THE WIRELESS ACCESS POINT/WIRELESS ROUTER
If the printer is too far away from the access point, it will not be able to communicate with other devices on the
network. For most indoor wireless networks, the maximum distance between the access point and the printer is
approximately 100 feet (30 meters). This distance could be longer or shorter, depending upon the layout of the
network and the limitations of the access point.
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.
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
