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. 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, wrong control of signal conversion by exchanger)
3. Acquire a log.
• Protocol trace list for errors
• Line information for both fax machine and remote
station
• Machine management list (CSV save), activity report
• SysLogALL
It cannot be dissolved by settings, so acquire a log.
• Protocol trace list for errors

2. Possibility of line defect (example: packet loss, echo,
distortion)
How to correct
1. Set the coding method to MH/MR/MMR.
2. It cannot be dissolved by settings, so acquire a log.
• Original (on fax machine if possible)
• Protocol trace list for errors
• Machine management list (CSV save), activity report
1. Enable communication with ECM.
If ECM has been already set to ON on your machine,
request the sending end to do it.
2. Set the account of EOL regarded as RTC lower.
1. Ask the fax machine to check that no multiple pages
have been read together, and to send it again.
2. Request the fax machine to resend with TTI information
while keeping the length within 1000 mm.
1. Set the coding method to MH/MR/MMR.
2. Turn OFF V.34.
1. It cannot be dissolved by settings, so acquire a log.
