CHAPTER 7 TROUBLESHOOTING
##783 [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
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
significant signal was received correctly thereafter.
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
office and/or Technical Center.
##784 [TX]
In ECM transmission, ERR was received after transmission of
EOR-EOM
The line condition is poor, and the other party cannot often receive the image sig-
nal correctly.
1. Increase the transmission level so that the other party may receive the image
signal correctly.
2. Adjust the NL equalizer so that the other party may receive the image signal
correctly.
The other party malfunctioned because of an echo.
1. Using a manual call, press the Start button after hearing the 1st DIS from the
other party.
2. To prevent response to the 1st DIS from the other party, put a relatively long
pause to the telephone number when registering an auto-dialing number.
3. Ask the operator of the other party to provide echo remedy 1.
4. Ask the operator of the other party to decrease the transmission level so that the
other party will not receive an echo.
##785 [TX]
In ECM transmission, no significant signal can be received after
transmission of EOR-EOP, and the allowed number of procedure
signal re-transmissions was exceeded
The line condition is poor, and the other party cannot receive EOR-EOP correctly.
1. Increase the transmission level so that the other party may receive EOR-EOP
correctly.
2. Adjust the NL equalizer so that the other party may receive EOR-EOP cor-
rectly.
3. Add an echo protect tone to the V.29 modem signal for transmission.
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
signal may be received correctly.
