							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:
The solutions below are for infrastructure networks. If you are using an ad hoc network, adjust the computer
when the solution suggests adjusting the access point.
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. Arrange your printer and access point so
that the signal is not blocked by such 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. Turn off 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.
ARRANGE THE NETWORK TO REDUCE SIGNAL ABSORPTION
Even when the wireless signal is able to pass through an object, it is slightly weakened. If it passes through too
many objects, it can be significantly weakened. All objects absorb part of the wireless signal when it passes through
them, and certain types of objects absorb enough to cause communications problems. Place your access point as
high in the room as possible to avoid signal absorption.

							Can I use my printer on a USB and a network connection at the same
time?
Yes, the printer supports a simultaneous USB and network connection. The printer can be configured in the following
ways:
Locally attached (connected to a computer using a USB cable)
Wireless network
Wireless network and locally attached simultaneously
Note: Wireless connectivity is available on selected models only.
What is a MAC address?
A Media Access Control (MAC) address is a 48-bit identifier associated with the hardware of network equipment. The
MAC address may also be called the physical address because it is connected to the hardware of a device instead of
its software. The MAC address is displayed as a hexadecimal number in this format: 01-23-45-67-89-AB.
Every device capable of communicating on a network has a MAC address. Network printers, computers, and routers,
whether Ethernet or wireless, all have MAC addresses.
While it is possible to change the MAC address of a network device, it is not common practice  t o  d o  s o .  F o r  t h i s  r e a s o n ,
MAC addresses are considered permanent. IP addresses are easily changed, so MAC addresses are a more reliable
method of identifying a specific device on a network.
Routers with security capabilities may allow filtering of MAC addresses on networks. This allows a managed list of
devices to access the network, identified by their MAC addresses. MAC address filtering can help prevent access on
the network from unwanted devices, such as from intruders on a wireless network. MAC address filtering can also
prevent legitimate access if you forget to add a new device to the router's list of allowed addresses. If your network
uses MAC address filtering, be sure to add the MAC address of the printer to the list of allowed devices.
How do I find the MAC address?
Most network equipment has a unique hardware identification number to distinguish it from other devices on the
network. This is called the Media Access Control (MAC) address.

							The MAC address is a series of letters and numbers located on the back of your printer.
UAA: XX   XX   XX   XX   XX   XX
UAA:
XX   XX   XX   XX   XX   XX
Note: A list of MAC addresses can be set on an access point (router) so that only devices with matching MAC addresses
are allowed to operate on the network. This is called MAC filtering. If MAC filtering is enabled in your access point
(router) and you want to add a printer to your network, the MAC address of the printer must be included in the MAC
filter list.
What is an IP address?
An IP address is a unique number used by devices (such as a wireless printer, computer, or wireless access point) on
an IP network to locate and communicate with each other. Devices on an IP network can communicate with each
other only if they have unique and valid IP addresses. A unique IP address means no two devices on the same network
have the same IP address.
An IP address is a group of four numbers separated by periods. An example of an IP address is 192.168.100.110.
What is TCP/IP?
Networks are able to function because computers, printers, and other devices are able to send data to each other,
either through cables or by using wireless signals. This transfer of data is made possible by sets of data transmission
rules called protocols. A protocol can be thought of as a language, and like a language, it has rules allowing participants
to communicate with each other.
Different types of networks use different protocols, but Transmission Control Protocol/Internet Protocol (TCP/IP) is the
most popular. TCP/IP is used to send data over the Internet as well as over most corporate and home networks.
Because computers do not understand words and instead rely upon numbers for communication, TCP/IP requires
that every device on a network using TCP/IP to communicate must have an IP address. IP addresses are essentially
unique computer names in a numeric format, used to transfer data around a network. IP addresses allow TCP/IP to
confirm requests for and receipt of data by various devices on the network.

How to locate a printer IP address
You can locate the printer IP address by viewing the printer network setup page.
How are IP addresses assigned?
An IP address may be assigned automatically by the network using DHCP. Once the printer is set up on a computer,
the computer sends all print jobs across the network to the printer using this address.
If the IP address is not automatically assigned, you will be asked during wireless setup to manually enter an address
and other network information after selecting your printer from the available list.
What is a key index?
A wireless access point (wireless router) can be configured with as many as four WEP keys. Only one key is used on
the network at a time, however. The keys are numbered, and the number of a key is referred to as its key index. All
devices on the wireless network must be configured to use the same key index when multiple WEP keys are configured
on the wireless access point.
