Epson WorkForce 645 User Manual

You must install the software on every computer from which 
you want to print. For the first installation, we recommend 
using a temporary USB cable connection to simplify wireless 
setup. After the printer is connected to the network, you will 
be prompted to remove the cable.

If you’re using Mac OS X 10.6 or 10.7, or you don’t have 
a USB cable, you will need to use the control panel on the 
printer to select wireless settings. Follow the instructions on 
your computer screen during software installation; they will 
explain how to connect the printer wirelessly this way.

 Make sure you know your network name (SSID) and network 
password:

•  Network name 
•  Network password 
If you don’t have this information, contact the person who set 
up your network.

Make sure you have a USB cable (not included). 

Make sure you have an Ethernet

®

 network cable (not 

included). You must install the software on every computer 
from which you want to print. 

If you experience problems during setup, see below: 

•  Make sure you select the right network name (SSID).
•  If you see a firewall alert message, click 

Unblock or Allow 

to let setup continue.

•  If your network has security enabled, make sure you enter 

your network password (WEP key or WPA passphrase) 
correctly. If it has uppercase (

ABC) or lowercase (abc) 

letters, make sure you enter them correctly.
