Each IP-address on a network (private in your home, or public on the Internet) must be unique; hence "IP conflict" when two devices (computers or printers or iPod Touch) try to "claim" the same IP-address.
If you have configured a "static" IP-address into the printer, change it to an IP-address that is *NOT* used on your network.
Or, find the computer on your network that is using the same IP-address as your printer, and change its IP-address and reboot it.
In order to connect, your computer and your computer *MUST* have *DIFFERENT* IP-addresses.
An IP
address conflict occurs
when two computers on a LAN or the Internet have been assigned the same IP. IP
conflicts between two computers normally render either one or both of them
unusable for network operations.
How IP
Address Conflicts Happen
Two
computers can acquire conflicting IP addresses in any of several ways:
· A system administrator assigns two
computers on the LAN the same Static IP Address.
· A system administrator assigns a
computer a static IP address within the local network's DHCP range (dynamic IP
range), and the same address is automatically assigned by the LAN DHCP
server.
· A malfunction in the network's DHCP
server allows the same dynamic address to automatically be assigned to multiple
computers.
· An ISP accidentally assigns two
customers the same IP address (either statically or dynamically).
· A mobile computer is put into standby
/ hibernate mode and then awakened later.
Note that
other forms of IP conflicts can also occur on a network. For example, one computer
may experience an IP address conflict with itself if that computer is
configured with multiple Network Adapters. System administrators may also
create IP conflicts by accidentally connecting two ports of a network switch or
router to each other.
Recognizing
IP Address Conflicts
On most
Microsoft Windows computers, if you attempt to set a fixed (static) IP address
that is already active on the local network, you will receive the following
pop-up error message:
The static IP address that was just configured is already in use on the
network. Please reconfigure a different IP address.
On newer
Microsoft Windows computers having dynamic IP conflicts, you should receive a
balloon error message in the Taskbar as soon as the operating system detects
the issue:
There is an IP address conflict with another system on the network.
Sometimes,
especially on older Windows computers, a message similar to the following may
instead appear in a pop-up window:
The system has detected a conflict for IP address...
On Mac or
Linux computers, a similar message will normally appear on screen.
Resolving IP
Address Conflicts
Try the
following remedies for IP conflicts:
1. For
networks where IP addresses are fixed (statically assigned), ensure each local
host is configured with a
unique IP address.
2. If your
computer has a dynamically assigned address, releasing
and renewing its IP address can
workaround IP address conflicts.
3. If your home router is believed to have a
faulty DHCP server causing IP conflicts on the home network, upgrading the
router firmware may resolve this problem.
When configuring an address for the printer, the IP configuration might look like (just an example):
IP Address - 192.168.1.2
Subnet Mask - 255.255.255.0
Default Gateway - 192.168.1.1
It's important to note that even though you are not using any IP addresses in the default range for DHCP, the Subnet Mask and Default Gateway addresses will be THE SAME.
If you have another device on your network that will be assign a fixed address, you would use for example:
IP Address - 192.168.1.3
Subnet Mask - 255.255.255.0
Default Gateway - 192.168.1.1
For any other devices, just increment the IP address by one, 192.168.1.4, 192.168.1.5, etc and use the same Subnet Mask and Default Gateway.

All devices on a network (PC, Laptop, printer, etc.) must each have a unique IP address. If the address of the Printer and your PC are different, that is good. There is some other conflict...: 1. Please post the IP Address of the printer and your computer. 2. The printer may be in conflict with a firewall or some other device, like a WiFi Access Point. 3. Two devices have (maybe) 192.168.1.1 or 192.168.1.0 or 192.168.0.1 4. All devices have to have the SAME first THREE sets of numbers (The network number) and a different fourth number (the node number): example: Network: 192.168.1.x Node: xxx.xxx.x.3 Your IP address: go to a Command Prompt: [Start] [ Run] "cmd" type ipconfig (and press the enter key) Your IP Address will be listed.
