Paper Tray
The MFC ejects paper with printed surfaces face down into the paper tray at the
front of the machine. When you use transparencies, remove each sheet
immediately after printing, to prevent a paper jam or curled sheets.
Simultaneous Printing/Faxing
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 then
resumes when copying or fax receiving is complete. Fax sending continues
during PC printing.
