This machine is set to send/receive faxes in Error Correction Mode (ECM). If the recipient's fax machine is compatible with ECM, ECM automatically corrects errors and resends the fax.
If the sender's or recipient's fax machine is not compatible with ECM, the fax will be sent/received without automatic error correction.
To receive color faxes, make sure that ECM RX in Adv. communication settings in Advanced FAX settings under FAX settings is set to ON.
To disable ECM transmission/reception, set ECM TX and ECM RX in Adv. communication settings to OFF.
Transmission may take longer when ECM is enabled.
