When the message <Toner is nearly out.> appears when
receiving a fax
Printing of the fax is interrupted and the received data will be
stored in the memory.
If <Continue Print. When Toner Is Nearly Out> is set to
<On>
You can keep printing fax documents or reports without replacing
a toner cartridge. However, the printed documents may be light
or blurred because of lack of toner. The data is erased when
the documents are printed out, so you cannot print the same
documents again.
