Product Does Not Appear in Mac Printer Window

If your product does not appear in the Mac printer window, try these solutions:
• Turn your product off, wait 30 seconds, then turn it back on again.
• If you are connecting the product via Wi-Fi Protected Setup (WPS) and the Wi-Fi icon on your
product's LCD screen is not lit, make sure you select one of the WPS options from the product control
panel within 2 minutes of pressing the WPS button on your router.
• If you are connecting the product wirelessly via EpsonNet Setup and the Wi-Fi icon does not appear lit
on your LCD screen, make sure your product software was installed correctly. If necessary, reinstall
your software.
Note: If you are using a 5 GHz wireless router, set the router to operate in dual band (2.4 GHz and
5 GHz) mode. If your router uses a single network name (SSID) for both the 2.4 GHz and 5 GHz band,
give each band its own network name (SSID) instead, such as Home Network 2.4 GHz and Home
Network 5 GHz. See your router documentation or contact your internet service provider for instructions.
