• Soft switch function description
Used to protect from echo in reception.
SW-A1 No. 2 Forced 4800BPS reception
When line conditions warrant that receptions take place at 4800 BPS repeatedly.
It may improve the success of receptions by setting at 4800BPS.
This improve the receiving document quality and reduces handshake time due to fallback during training.
SW-A1 No. 3 Footer print
When set to "1", the date of reception, the sender machine No., and the page No. are automatically recorded at the end of reception.
SW-A1 No. 4 Length limitation of copy/send/receive
Used to set the maximum page length.
To avoid possible paper jam, the page length is normally limited to 0.6 meter for copy or transmit, and 1.5 meters for receive.
It is possible to set it to "No limit" to transmit a long document, such as a computer print form, etc. (In this case, the receiver must also be set to no limit.)
SW-A1 No. 5 CSI transmission
(CSI TRANSMISSION) is a switch to set whether the machine sends or does not send the signal (CSI signal) informing its own telephone No. to the remote fax. machine when information is received. When "nonsending" is set, the telephone No. is not output on the remote trans- mitting machine if the remote transmitting machine has the function to display or print the telephone No. of receiving machine, using this CSI signal.
SW-A1 No. 6 DIS receive acknowledgment during G3 transmission
Used to make a choice of whether reception of DIS (NSF) is acknowl- edged after receiving two DISs (NSFs) or receiving one DIS (two NSFs). It may be useful for overseas communication to avoid an echo sup- pression problem, if set to 1.
SW-A1 No. 7 Non-modulated carrier for V29 transmission modem
Though transmission of a
SW-A1 No. 8 EOL (End Of Line) detect timer
Used to make a choice of whether to use the
This is effective to override communication failures with some facsimile models that have longer EOL detection.
SW-A2 No. 1 ~ No. 4 Modem speed
Used to set determine the initial modem speed. The default is 9600BPS. It may be necessary to program it to a slower speed when frequent line fallback is encountered, in order to save the time required for fallback procedure.
SW-A2 No. 5 Sender’s information transmit
(SENDER’S INFORMATION TRANSMISSION) is a switch to set the function to print the content of HEADER PRINT described in the passcode list at the front end of receiver’s original when original is sent to the remote machine.
If this switch is set to "NO", the HEADER PRINT is not output at the receiving machine.
SW-A2 No. 6 H2 mode
Used to determine reception of H2 mode (15 sec transmission mode). When set to OFF, H2 mode reception is inhibited even though the trans- mitting machine has H2 mode function.
Used to determine communication error treatment when RTN is sent by occurrence of a received image error in G3 reception. When it is set to "1", communication error is judged as no error.
SW-A2 No. 8 CNG transmission
When set to "0" , this model allows CNG transmission by pressing the Start key in the key pad dialing mode. When set to "1", CNG transmis- sion in the key pad dialing mode cannot be performed. In either case, CNG transmission can be performed in the auto dial mode.
SW-A3 No. 1, No. 2 CED tone signal interval
For international communication, the 2100Hz CED tone may act as an echo suppression switch, causing a communication problem.
Though
TX RX
CED
T
DIS
Used to select the MR coding enable or disable.
Set to "0".
SW-A4 No. 1 ~ No. 5 Signal transmission level
Used to control the signal transmission level in the range
The factory setting is at
If set to "1", protocol is printed at communication error.
SW-A4 No. 7 Protocol monitor
Normally set to "0". If set to "1", communication can be checked, in case of troubles, without using a G3 tester or other tools.
When communication FSK data transmission or reception is made, the data is taken into the buffer. When communication is finished, the data is analyzed and printed out. When data is received with the line monitor
SW-A4 No. 8 Line monitor
Normally set to "0". If set to "1", the transmission speed and the recep- tion level are displayed on the LCD. Used for line tests.
SW-A5 No. 1, No. 2 Digital line equalization setting (Reception)
Line equalization when reception is to be set according to the line char- acteristics.
Setting should be made according to distance between the telephone and the telephone company central switching station.
Set to "0".
Used to select error criterion for sending back RTN when receiving im- age data.
When use the Anti junk fax function, set to "1".
SW-A6 No. 1 Auto gain control (MODEM)
When this mode is enabled, if the reception signal level is under 31dBm. The modem itself controls the signal gain automatically.
