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

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

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, communication may take a little longer than communication that does not use ECM checking. To reduce the transmission time, you can send 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.
