System --> Admin Menu --> Fax Settings --> Ans Select.
Corrective Action: Change the answering mode from TEL Mode to other
mode (i.e., FAX Mode, TEL/FAX Mode, Ans/FAX Mode, DRPD Mode...).

Cause: An attempt was made to send document data in excess of the
available memory capacity.
Corrective Action: On the receiving side, wait until the current fax job is
printed completely.

resolve the problem.
