Solution
IMPORTANT!
Before you begin, make sure that you have an Ethernet cable
and a laptop with at least Windows 7
for the operating system (OS
).- Connect the printer to the laptop using anEthernet cable.If it was previously connected to a wired network, perform a power-on-reset (POR) on the printer.
- Perform any of the following procedures to acquire theIP addressandSubnet mask.
- Print the printer’sNetwork Setup Pagereport.
- View the IP address and subnet mask from the printersNetwork Setup Menu.
- Ask the user for the IP address and Subnet mask.
- If the IP address cannot be known, change the IP address through the Network Setup Menu to169.254.1.89with a Subnet mask of255.255.0.0.Perform a power-on-reset (POR) on the printer if it was previously connected to a wired network.Customer Printer IP Address:__ __ __.__ __ __.__ __ __.__ __ __Subnet Mask: __ __ __.__ __ __.__ __ __.__ __ __
- On the user's personal computer (PC), clickControl Panel>Network and Sharing Center>Change Adapter Settings
- Right-click on Local Area Connection, and selectProperties.
- Double-click Internet Protocol Version 4 (TCP/IPv4).
- Select Use the following IP address, and enter anIP addressidentical to the one from the printer except increase the last set of digits by 1 (i.e., 169.254.1.89 increased by1=169.254.1.90), and sameSubnet Maskas the device (i.e.,255.255.0.0), then leave theDefault Gatewayblank.
- Type the user printer IP address into the address bar of your browser to access the printer’s embedded web server (EWS).Use theprinter's actual IP addressandnotthe IP address that was increased by1.
