Sending a Fax after Canceling ECM Mode ([ECM])

ECM

ECM is an error correction mode defined by ITU-T (International Telecommunication Union - Telecommunication Standardization Sector).

If fax machines support the ECM, they check for fax data errors while communicating with each other. Image disturbances due to telephone line noise can be suppressed.

By default, this machine uses ECM for transmission. If the noise level is high, the communication may take a little longer than the communication without using ECM checking. To reduce the transmission time, you can transmit faxes with ECM turned off. However, an image error or communication error may occur depending on the specified communication time value, so change the value to suit conditions.

Tips

  • When registering destinations with an address book, you can specify whether to send faxes in the ECM mode in addition to registering fax numbers.

  • If the ECM function is canceled, the following functions cannot be used together.
    V.34 OFF, Polling TX, Polling TX (Bulletin Board), Polling RX, Polling RX (Bulletin Board).
