Check the error correction setting
Usually, the product monitors the signals on the telephone line while it is sending or receiving a fax. If the
product detects an error during the transmission and the error-correction setting is On , the product can
request that the portion of the fax be resent. The factory-set default for error correction is On .
You should turn off error correction only if you are having trouble sending or receiving a fax, and you are
willing to accept the errors in the transmission. Turning off the setting might be useful when you are trying to
send a fax overseas or receive one from overseas, or if you are using a satellite telephone connection.
