ECM OFF

The Error Correction Mode (ECM) is turned off when sending data. ECM is an error correction mode defined
by ITU-T (International Telecommunication Union - Telecommunication Standardization Sector). Fax
machines equipped with the ECM feature communicate with each other, confirming that the data sent is free
of errors. Thus, communication can be made free from disturbances due to line noises, etc. If noises
frequently occur, it may take a slightly long time to complete a communication compared with ECM OFF.
After sending has been ended, this machine automatically returns to ECM ON.
Reference
- This machine sends faxes in ECM ON unless ECM OFF is specified.
- This function cannot be used together with the following functions.
– Polling RX
– Polling TX

V.34 OFF

V.34 OFF
V34 is a communication mode used for super G3 fax communication. When the remote machine or this
machine is connected to a telephone line via PBX, however, you may not establish a communication in the
super G3 mode depending on telephone line conditions. In this case, it is recommended that you turn V34
off to send data. After sending has been completed, this machine automatically returns to the V34 mode.
Reference
- This function cannot be used together with the following functions.
– Polling RX
– Polling transmission
– Bulletin board registration
– Bulletin board polling reception
– ECM OFF
Check Dest. & Send
The specified fax number is compared with the remote fax number (CSI) and data is sent only when those
fax numbers match. If they do not match, the communication will fail; therefore preventing a sending error.
Reference
- To use the Check Dest. & Send, you must register the local fax number in the remote machine in
advance.

Select Line

You can specify [Line 1] or [Line 2] for sending data when two fax kits are installed. Specify the line used for
transmission. If you select "Not Set", either Line 1 or Line 2 whichever is not busy is used for transmission. If
both lines are idle, Line 1 is used first.
Reference
- You cannot specify a line when "Line 2 Setting" is set to "RX Only" in "Multi Line Usage". For details on
the Multi Line Usage function, refer to the "User's Guide [Network Scan/Fax/Network Fax Operations]".
- To use two lines as external and extension lines, be sure to specify the line to be used. If you select
"Not Set", a sending failure may occur.
