Simultaneous Printing/Fax
Your MFC can print data from your computer while sending or
receiving a fax, or while scanning information into the computer.
However, when the MFC is copying or receiving a fax on paper, it
pauses the PC printing operation, and resumes when copying or
fax receiving is complete. Fax sending will continue during PC
printing.
