AL-2020/2035/2040/2050/2060 FAX SOFT SWITCH 12 - 29

SW67 No.5–No.8 Inhibited to use

SW68 No.1, No.2 Line open delay time in dial test

Used to set time interval between end of dialing and opening the
line. Valid only in dial test of simulation.

Default: 0 0 (2sec)

SW68 No.3, No.4 Inhibited to use

SW68 No.5–No.8 T1 timer setup

Used to set time for connection of the line when the remote machine
does not respond in FAX communication.

The time of ITU-T standard is 35 ± 5sec.

Setting is made in binary input in the increment of 5sec.

Default: 40sec

SW69 No.1–No.8 Inhibited to use

SW70 No.1–No.3 Inhibited to use

SW70 No.4 Reception waiting time between frames

Used to set reception wait time between frames.

Default: 0 (3.4sec)

SW70 No.5, No.6 Preamble send time of 300bps

Used to set preamble send time of 300bps.

Default: 0 1 (1.0sec)

SW70 No.7, No.8 RCP send times

Used to set number of times of RCP frame send.

Default: 0 0 (3 times)

SW71 No.1–No.8 Inhibited to use

SW72 No.1 EYE-Q check

Used to set TCF check in TCF reception.

When set to 1, check is made only with EYE-Q value (EQM value).
Therefore, TCF check is loosely made.

When set to 0, check is made with received data and EYE-Q value
(EQM value).

Default: 0 (0 reception & EYE-Q check)

SW72 No.2 ERR frame reception operation

Used to set operations when an image with an error frame is
received.

Default: 0 (Not continue process. (Error))

SW72 No.3, No.4 Waiting time for CED/ANSam send
start

Used to set waiting time from when the line is connected and the
machine enters FAX receive state to when CED/ANSam signal is
send to the line.

Default: 0 0 (2.25sec)

SW72 No.5 RTC EOL send times

Used to set number of times of RTC EOL send.

Default: 1 (6 times)

SW72 No.6 Inhibited to use

SW72 No.7, No.8 CNG send start

Used to set CNG send time.

Default: 0 0 (0.5sec)

SW73 No.1–No.8 Inhibited to use

SW74 No.1–No.4 Print effective image area sub scan
lead edge void

Used to set print image area void.

The void amount on the lead edge in the sub scan direction can be
adjusted. When the set value is increased, the void amount on the
lead edge is increased.

Setting is made in binary input in the increment of 16 lines.

Default: 32 lines

SW74 No.5–No.8 Inhibited to use

SW75 No.1 Manual calibration setting when sending

Setting to execute the manual calibration or not when sending.

In case of an abnormal current waveform, the auto calibration fails
and the DTFM signal is deformed. This setting provides the counter-
measure against that problem.

Default: 0 (OFF)

SW75 No.2 Manual calibration setting when a signal
arrives

Setting to execute the manual calibration or not when a signal
arrives.

In case of an abnormal current waveform, the auto calibration fails
and the transmission is affected. This setting provides the counter-
measure against that problem.

Default: 0 (OFF)

SW75 No.3, No.4 Communication end sound (Buzzer
sound length) setting

Used to set the length of communication end buzzer sound in com-
munication.

Default: 0 0 (3sec)

SW75 No.5–No.8 Print effective image area main scan
void

Used to set void amount in print image area.

The void amount in the main scan direction can be adjusted. When
the set value is increased, the margins on the right and the left are
increased.

Setting is made in binary input in the increment of 16 dots.

Default: 48 dots

SW76 No.1 Scan magnification ratio adjustment
(main scan) flag

Used to set the main scan magnification ratio in scan.

Bit 1 indicates plus or minus of the magnification ratio.
