Since the information contained in the fax
may be lost if it is printed in this condition, the
received fax will not be printed and will be
stored in the machine's memory until the ink
cartridge is replaced. You must manually

memory. You can change the setting so that
the received fax is forcibly printed out instead
of being stored in the memory, but all or part
of the fax information may not be printed
because of the ink out condition.
