The connection method differs depending on your telephone line.

If you pick up the handset of the telephone that is connected in parallel during fax transmission or reception, the fax image may be corrupted or a communication error may occur.

Such services as Caller ID, etc. may not operate properly on the telephone.

Do not connect the printer and / or telephones in parallel

If you cannot avoid parallel connections, set the receive mode to TEL priority mode, understanding that the above problems may occur. You will only be able to receive faxes manually.
