R00 Recepti Unable to detect fax
on signal (CNG/DCS) from
(Ph.B) the remote station by the
time of T1 timeout
R01 Mixed Unable to detect the
size DCS (reception ability
recepti signal) from the remote

(Ph.B') after received the
change instructions
(PPS-EOM) of original
size or resolution
R02 Recepti A DCN is received when

unexpected command
during DCS waiting)
How to correct
Specify the line to be used to send.
Change the line specification of the abbreviated
registration.
(Since the abbreviated registration has been imported with
an uninstalled line specified, the abbreviated registration
must be modified.)
Check for any telephone line connection error.
A breakage on underfloor wiring may be a possible cause.
How to correct
1. Set the Receive Signal Detection Mode to No. of Times. [Network] -> [Network Setting 1] ->
2. Set the 1300Hz Detection setting to OFF if possible.
(Fax destination: Japan only)
3. For 1300Hz Detection (JP), connect the ground for the
MFP/TA/PBX. (Fax destination: Japan only)
4. Change the setting of 1300Hz detection frequency. (Fax
destination: Japan only)
5. Turn ON the monitor speaker, and check if the fax signal
from the remote station can be heard. If cannot, it is judged
as a wrong number.
6. Change the lowest reception sensitivity to -43 dBm.
Change the signal transmission level to -15 dBm.
7. Extend T1 timer.
Extend the response waiting time. (only for amount of
extended T1 timer)
• Increase by +10 seconds.
* If no effect is obtained, return the setting.
8. Extend the DIS retransmission interval.
1. Change the lowest reception sensitivity to -43 dBm.
Change the signal transmission level to -15 dBm.
2. Extend T1 timer.
Extend the response waiting time. (only for amount of
extended T1 timer)
• Increase by +10 seconds.
* If no effect is obtained, return the setting.
3. If the error occurs on the specific destination, ask it to
pay attention not to send fax with mixed-size original or
incorrect resolution. (Due to issues on remote station)
1. Change the lowest reception sensitivity to -43 dBm.
Change the signal transmission level to -15 dBm.
2. Extend the DIS retransmission interval.
* If no effect is obtained, return the setting.
1. Extend V.21 signals interval.
Increase by +20 ms.
* If no effect is obtained, return the setting.
2. Extend the DIS retransmission interval to 4.5 seconds.
* If no effect is obtained, return the setting.
