To set up the Epson WorkForce WF-3640 printer, follow these steps based on the official Epson guidelines and resources:

1. **Prepare the Printer:**
– Unpack the printer, remove all protective materials, and install the included ink cartridges.
– Load paper into the input tray.
– Connect the power cord and turn on the printer.
– The printer will prime the ink, which uses some ink and can take a few minutes. Do not turn off the printer during this process to avoid wasting ink[2][4].

2. **Install Software and Drivers:**
– If using a computer, download the latest **Drivers and Utilities Combo Package** from Epson’s official website for your operating system (e.g., macOS or Windows)[1][3].
– For macOS, download and run the Epson WorkForce WF-3640 combo package installer which includes printer drivers, scanner drivers, Epson Event Manager, and other utilities[1].
– For Windows, download the driver package, run the installer, and when prompted, select your connection type (wireless, wired, or USB)[3].

3. **Connect the Printer to Your Network or Computer:**
– For **Wireless Setup**:
– Make sure you know your Wi-Fi network’s SSID (name) and password.
– You can connect using the printer’s control panel buttons if no USB cable is available or via a temporary USB cable for an easier setup[3].
– Use the printer’s control panel or the setup wizard in the software to select your Wi-Fi network and enter the password[2][3].

– For **Wired Network Connection**:
– Connect an Ethernet cable from the printer to your router or network switch[2].

– For **USB Connection**:
– Connect the USB cable between the printer and your computer when prompted during installation[2].

4. **Complete Setup:**
– Follow on-screen instructions to complete driver/software installation and confirm the printer’s status.
– Configure additional settings such as paper size/type through the printer control panel or software.
– If setting up on Mac, ensure Epson Software Updater is installed for updates[2].
– After setup, enable any necessary firewall permissions to allow communication with the printer[3].

5. **Additional Configuration:**
– The printer supports fax utilities, scan utilities, and mobile printing via Epson Connect features such as Epson Email Print and Remote Print.
– Detailed user and start guides provide more instructions on using advanced features and maintaining the printer[2][4].

If you do not have a CD/DVD drive, always download the latest software from Epson’s official site[2].
