How to correct
1. Turn OFF V.34.
2. Check if an error has occurred on the machine on other
end of line first.
Turn OFF V.34.
How to correct
1. Dissolve the high load issues.
2. It cannot be dissolved by settings, so acquire a log.
(since an error may occur on the DIS received from the
remote station or altered by exchangers in midway)
• Protocol trace list for errors (including remote station)
• Line information for both fax machine and remote
station
• Machine management list (CSV save), activity report
• SysLogALL
1. Check the fax machine for that if a job is canceled or a
communication error occurred.
2. Enable communication with ECM.
If ECM has been already set to ON on your machine,
request the sending end to do it.
3. Set 000E000D bit7 to 0 to turn OFF the timer.
4. Possibility of line defect (due to wrong control of signal
conversion by exchanger)
1. Change the lowest reception sensitivity to -43 dBm.
Change the signal transmission level to -15 dBm.
2. Possibility of line defect (example: packet loss, echo,
distortion)
How to correct
1. Enable communication with ECM.
If ECM has been already set to ON on your machine,
request the sending end to do it.
2. Possibility of line defect (example: packet loss,
distortion)
1. Turn OFF and ON the main power switch.
2. Set the coding method to MH/MR/MMR.
3. If the error reoccurs on the specific remote station, it
cannot be dissolved by settings, so acquire a log.
• Protocol trace list for errors (including remote station)
• Line information for both fax machine and remote
station
• Machine management list (CSV save), activity report
• sysLogALL
1. Check the connection of the fax board USB cable and
the power cord.
2. Turn OFF and ON the main power switch.
3. If the error reoccurs on the specific remote station, it
cannot be dissolved by settings, so acquire a log.
