• 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.
• Check your inbox and delete faxes after reading or printing them. If the inbox is full, the product cannot
receive faxes.
• If you cannot send faxes at a specified time, make sure the date and time are set correctly on the
product.
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.
