Inch-mm conversion before tx
Bit 1 Bit 0 Setting
0 0 Inch-mm
conversion
available
0 1 Inch only
1 0 Not used
1 1 Disabled
The machine uses inch-based resolutions for
scanning. If “inch only” is selected, the printed copy
may be slightly distorted at the other end if that
machine uses mm-based resolutions.
If the setting is “Disabled”, the bit switch setting is
used.

DIS/NSF detection method
Bit 3 Bit 2 Setting
0 0 First DIS or
NSF
0 1 Second DIS or
NSF
1 0 Not used
1 1 Disabled
(0, 1): Use this setting if echoes on the line are
interfering with the set-up protocol at the start of
transmission. The machine will then wait for the
second DIS or NSF before sending DCS or NSS.
If the setting is “Disabled”, the bit switch setting is
used.
4
V.8 protocol
0: Off
1: Disabled
If transmissions to a specific destination always end
at a lower modem rate (14,400 bps or lower),
disable V.8 protocol so as not to use V.34 protocol.
0: V.34 communication will not be possible.
If the setting is “Disabled”, the bit switch setting is
used.
5
Compression modes available
in transmit mode
0: MH only
1: Disabled
This bit determines the capabilities that are informed
to the other terminal during transmission.
If the setting is “Disabled”, the bit switch setting is
used.
6
to
7
ECM during transmission
Bit 7 Bit 6 Setting
0 0 Off
0 1 On
1 0 Not used
1 1 Disabled
For example, if ECM is switched on but is not
wanted when sending to a particular terminal, use
the (0, 0) setting.
Note that V.8/V.34 protocol and JBIG compression
are automatically disabled if ECM is disabled.
If the setting is “Disabled”, the bit switch setting is
used.
