Error Catego Contents of error
code ry
R04 Unable to identify the
analysis result and the
communication mode of
the received DCS signal
R06 Recepti An image data error in
on all frames exceeds a
(Ph.D) predetermined
frequency
R07 Recepti Unable to detect image
on data
(Ph.C) Example: The fax
machine is
disconnected, or the
image data cannot be
identified due to a line
defect.
R08 Signal interrupted while
receiving image data
Example: The image
data terminal cannot be
detected and the post
message (PPS-EOP/
MPS/NULL) cannot be
detected.
R09 Recepti Received the DCN when
on waiting the post
(Ph.D) message (PPSEOP/
MPS/NULL)
Example: The remote
station is disconnected
due to exceeded number
of times for
retransmission
(Also occurs after
returning the MCF/PPR)

R10 Recepti Protocol error (received
on unexpected command
(Ph.D) during waiting the post
message)
How to correct
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
1. Change the lowest reception sensitivity to -43 dBm.
Change the signal transmission level to -15 dBm.
2. Set the reception beginning speed to V.29/V.27ter.
3. Possibility of line defect (example: echo, distortion)
1. Change the lowest reception sensitivity to -43 dBm.
Change the signal transmission level to -15 dBm.
2. Implement test on the CFR return timing with each value.
(80ms/100ms/120ms/140ms/160ms/180ms)
3. Set the reception beginning speed to V.29/V.27ter.
4. Connect the ground for the MFP or TA.
5. Possibility of line defect (example: echo, distortion)
1. Check the telephone line.
2. Check the possibility that the job may be deleted from
the fax machine.
3. Change the lowest reception sensitivity to -43 dBm.
Change the signal transmission level to -15 dBm.
4. Set the reception beginning speed to V.29/V.27ter.
5. Possibility of line defect (example: echo, 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)
How to correct
1. Change the lowest reception sensitivity to -43 dBm.
Change the signal transmission level to -15 dBm.
2. Extend the PMC-PMR delay.
• Increase by +20 ms.
* If no effect is obtained, return the setting.
3. It cannot be dissolved by settings, so acquire a log.
