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.
