Cause
One or more of the ink cartridges are
near the end of their life. If one of the
colour ink cartridges is near the end
of its life and someone is sending you
a colour fax, your machine's
"handshake" will ask that the fax be
sent as monochrome. If the sending
machine has the ability to convert it,
the colour fax will be printed at your
machine as a monochrome fax.
The room temperature is too low.
The memory card is either corrupted,
incorrectly formatted, or there is a
problem with the memory card.
The memory card or USB flash drive
you are using already contains 999
files.
The memory card or USB flash drive
you are using does not have enough
free space to scan the documents.
There is no incoming call history. You
did not receive calls or you have not
subscribed to the Caller ID service
from your telephone company.
An ink cartridge is not installed
correctly.

the media drive (slot) of the machine
by inserting a working memory card.

memory card or USB flash drive only
if it contains less than 999 files.
