An error has occurred during a fax transmission or fax reception. Check the error code – that
indicates the origin of the error – on the corresponding Transmission Report (or Reception
Report) that is printed out in order to confirm the cause of the error.
The modular cord may not be connected properly to either the telephone or the line jack (L)
on the fax. Either that, or there is a problem with the telephone line. In this case, contact
your telephone company.
Dialing was accomplished, but connection to the other party was not possible. Check with the
other party.
The destination was dialed using a one-touch key that was designated for Encrypted
Transmission, but the Encrypted Transmission was not possible because the corresponding
Encryption Key is no longer registered in your fax.
