Overview
Guide to Error Code
When the Board has been installed and '1' is set for service data #1 SSSW SW01 bit 0,
communications ending in error will be indicated in the following reports using service error
codes: communications management report, reception result report, and error transmission
report.
You can also check the code of an error by making the following selections: System Monitor >
Fax > Detail.
The major error codes used by the Board are listed on the pages that follow. For information
on causes and remedies in connection with other error codes, see the "G3/G4 Facsimile Error
Code List" (HY8-23A0-020).
If the Board indicates a service error code, try the following:
- Increase the transmission level.
Set -8 (dBm) for service data #2 MENU parameter No. 007.
- Decrease the transmission level.
Set -15 (dBm) to service data #2 MENU parameter No. 007.
- Provide a remedy against echoes.
Change the following bit setting for service data #1 SSSW SW03:
Bit4 -> 1: to cause the machine to ignore the first DIS signal from the other party.
-> 0: to cause the machine to ignore the first DIS signal from the other party.
Bit5 -> 1: to cause the machine to transmit a tonal signal (1850 or 1650 Hz) in response to
the DIS signal from the other party.
-> 0: to cause the machine not to send a total signal (1850 or 1650 Hz) in response to
the DIS signal from the other party.
Bit6 -> 1: to cause the machine to send a 1850-Hz tonal signal if bit 5 is set to '1'.
-> 0: to cause the machine to send a 1650-Hz tonal signal if bit 5 is set to '1'.
Bit7 -> 1: to cause the machine to send a total signal before sending the CED signal.
-> 0: to causes the machine not to send a tonal signal before sending the CED signal.
- EPT (echo protect tone)
Change the setting of service data #1 SSSW SW03 bit 1:
4 Error Code > Overview > Guide to Error Code Error Code
Bit1 -> 1: to cause the machine to send EPT.
-> 0: to cause the machine not to send EPT.
- Adjust the NL equalizer.
Set '1' for serve data #2 MENU parameter No. 005.
- Decrease the transmission start speed.
Decrease the transmission start speed in user mode: System Settings > Communications
Settings > Fax Settings > Send Start Speed.
- Make the TCF evaluation standards lenient.
The Board does not offer a means by which to provide this remedy.
- Make the RTN transmissions conditions lenient.
Change parameters No. 2 through No. 004 of service data #3 NUMERIC Param.
No. 002: error rate for all lines; change it so that it is closer to 99%.
No. 003: number of lines in connection with bursts; change it so that it is closer to 99 lines.
No. 004: number of errors falling short of a specific number of lines in connection with
bursts; change it so that it is closer to 99.
- Increase the length of silence after reception of CFR.
Set '1' for service data #1 SSSW SW04 bit 4.
Bit4 -> 1: length of time during which a low-speed signal is ignored after transmission of
CFR; 1500 msec
-> 0: length of time during which a low-speed signal is ignored after transmission of
CFR; 700 msec
- <When using IPFAX> Change the mode of T.38 to "TCP".
Change "SIP TX Transport" to "TCP" in [Media (T.38) Settings].
