too quickly and the machine did
not detect it.
Take out the new ink cartridge and
re-install it slowly until it clicks.

Brother Innobella™ ink the
machine may not detect the ink
cartridge.
Use a new Genuine Brother Innobella™

properly.
Take out the new ink cartridge and re-
install it slowly until it clicks.
Cannot Print One or more of the ink cartridges
are empty. The machine will stop
all print operations. While memory
is available, black & white faxes
will be stored in the memory. If a
sending machine has a color fax,
the machine's
‘handshake’ will
ask that the fax be sent as black &
white. If the sending machine has
the ability to convert it, the color
fax will be stored in the memory
as a black & white fax.
Replace the empty ink cartridges. (See
Replacing the ink cartridges on page 161.)
Comm.Error Poor telephone line quality
caused a communication error.
Send the fax again or connect the machine
to another telephone line. If the problem
continues, call the telephone company and
ask them to check your telephone line.

that is not in Polled Waiting mode.
Check the other fax machine's polling
setup.

completely.
Lift the scanner cover and then close it
again.
The ink cartridge cover is not
completely closed.
Firmly close the ink cartridge cover until it
clicks.
Data Remaining Print data is left in the machine's
memory.
Press Stop/Exit. The machine will cancel
the job and clear it from the memory. Try to
print again.
Disconnected The other person or other
person's fax machine stopped the
call.
Try to send or receive again.

fed properly, or the document
scanned from the ADF was too
