##0780 [TX] In ECM transmission, no significant signal can be received after
transmission of EOR-EOM, and the allowed number of procedure
signal re-transmissions was exceeded
Cause:
The line condition is poor, and the other party cannot receive EOR-EOM correctly.
Remedy: (1) Increase the transmission level so that the other party may receive EOR-EOM
(2) Adjust the NL equalizer so that the other party may receive EOR-EOM cor-
(3) Add an echo protect tone to the V.29 modem signal for transmission.
Cause:
The line condition is poor, and the significant signal cannot be received correctly.

Ask the operator of the other party to increase the transmission level so that the sig-
nal may be received correctly.
##0782 [TX] In ECM transmission, DCN was received after transmission of
EOR-EOM
Cause:

Remedy: (1) Increase the transmission level so that the other party may receive EOR-EOM
(2) Adjust the NL equalizer so that the other party may receive EOR-EOM cor-
(3) Add an echo protect tone to the V.29 modem signal for transmission.
Cause:

##0783 [TX] In ECM transmission, the allowed number of procedure signal re-
transmissions was exceeded or a T5 time-over (60 sec) condition
occurred after transmission of EOR-EOM
Cause: The page buffer of the other party is full or is engaged; as such, although RNR was
received after transmission of EOR-EOM and then RR was transmitted, no signifi-
cant signal was received correctly thereafter.
Remedy:
(1) Start G3 mode, and transmit once again (Prohibit the ECM mode).
(2) Decrease the transmission start speed.
(3) Record the protocol on a DAT or MD, and have it analyzed by the local Canon
