Software Difficulties
“Unable to write to
LPT1” or “LPT1
already in use” error
message appears.
1. Make sure the machine is on (plugged into the
AC outlet) and that it is connected directly to the
computer using an IEEE-1284 bi-directional
parallel cable. The cable must not go through
another peripheral device (such as a Zip Drive,
External CD-ROM Drive, or Switch box).
2. Make sure the machine’s LCD screen is not
displaying an error message.
3. Make sure no other device drivers, which also
communicate through the parallel port, are running
automatically when you boot up the computer
(such as, drivers for Zip Drives, External CD-
ROM Drive, etc…) Suggested areas to check:
(Load=, Run= command lines in the win.ini file or
the Startup Group)
4. Check with you computer manufacturer to
confirm that the computer’s parallel port
settings in the BIOS are set to support a bi-
directional machine, i.e. (Parallel Port Mode-
ECP).
“MFC is Busy” or
“MFC Connect Failure”
error message appears.
MFC Connect Failure If the Brother machine is not connected to your PC
and you have loaded the Brother software, the PC
will show “MFC Connect Failure” each time you
restart Windows
®
. You can ignore this message or
you can turn it off by deselect the AutoLoad
PopUp check box in the Brother Control Center
chapter. (
See How to Turn Off AutoLoad, Page 14-2,
in On-Line Documentation (Owner’s Manual) on

Setup Printing Difficulties
I cannot print from my
application software.
Make sure the Windows
®
printer driver is installed
and that you selected it in your application
software.
Sometimes I get the
error message OUT OF
MEMORY when
printing certain
documents from
Windows
®
.
If you are using the supplied Windows
®
driver, turn
the error recover operation on in the Setup dialog
box and try again. Reduce the print resolution or
reduce the complexity of your document and try
again.
