This printer is set to send/receive faxes in Error Correction Mode (ECM). If the recipient's fax device is compatible with ECM, ECM automatically corrects errors and resends the fax.

 Note

• If the sender's or recipient's fax device 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 in Adv. FAX settings under Fax settings is set to ON.
   

  • Adv. FAX settings
     

  To disable ECM transmission/reception, set ECM TX and ECM RX in Adv. communication to OFF.

• Transmission may take longer when ECM is enabled.
