Settings	Description
[TX Method]	Change the communication mode based on the line conditions. [Overseas TX]: Select this option to send a fax to areas where communication conditions are poor. Faxes are sent at a lower speed. [ECM]: 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 sent data is free of errors. This prevents image blurring caused by telephone line noise. The communication time can be reduced by setting ECM to OFF for transmission. However, an image error or communication error may occur depending on the specified communication time value, so change the value to suit conditions. [V.34]: V.34 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 the V.34 mode off to send data.
[Check Dest. and Send]	Select this option to use the Check Dest. And Send function. The fax number specified for fax is checked against the destination fax number (CSI) and the fax is sent only when they match.
