• Print a fax connection report using your product control panel or fax software to help diagnose the
problem.
• Verify that the telephone wall jack works by connecting a phone to it and testing it.
• If there is no dial tone and you connected the product to a PBX (Private Branch Exchange) phone line
or Terminal Adapter, change the Line Type setting to PBX. If you still cannot send a fax, turn off the
product's dial tone detection setting. (Turning off the dial tone setting may cause the product to drop
the first digit of a fax number.)
• If you connected your product to a DSL phone line, you must connect a DSL filter to the phone jack to
enable faxing over the line. Contact your DSL provider for the necessary filter.
• If your telephone line has static, turn off your product's error correction mode fax communication
setting and try faxing again.
• Try lowering your product's fax speed setting.
• Make sure the error correction mode (ECM) setting is turned on if you are trying to send or receive a
color fax.
• If your telephone line uses call waiting and you have trouble receiving faxes, turn off call waiting to
prevent disruption of incoming faxes.
• If you have subscribed to a call forwarding service, the product may not be able to receive faxes.
Contact your service provider for assistance.
Note: If your product is connected to a VoIP (Voice over Internet Protocol) phone line, keep in mind that
fax machines are designed to work over analog phone lines. Epson cannot guarantee that fax
transmission will work when using VoIP.
If your phone line includes voice mail answering services, calls or faxes may be inadvertently received
by your voice mail service.
