Example #1: If you are having a telephone

comes through on your Call Waiting Caller ID
feature, you can verify that the second call is a

receive the fax call, by asking the first caller to
hang up to clear the line.
Example #2: If you are sending or receiving a
fax message while a Call Waiting Caller ID (or
other custom feature) signal comes through on
the line, the signal can temporarily interrupt or
disrupt the fax data.  BrotherÕs ECM feature
should help overcome this problem.  This
condition is related to the telephone system
industry, and is common to all devices that
send and receive information on a single,
shared line with custom features.  If avoiding a
slight interruption is crucial to your business, a
separate line with no custom features is
recommended.

Problem Using the HP Pavilion PC and the
ÒHP DEMOÓ Screen Saver
If you select the ÒHP DemoÓ screen saver on your HP Pavilion PC after
you have installed the Multi-Function Link¨ Pro software, the System.ini
file is overwritten and you cannot use the Brother machine to print, scan,
or for Remote Setup.
If you have used the HP Demo screen saver already, you must edit the
System.ini file as follows:
[boot]
;comm.drv=comm115.drv
comm.drv=brmfcomm.drv

If you do not want to edit the System.ini file, please change the screen
saver to another one and Re-install Multi-Function Link

Bi-Directional Parallel Ports
(nibble and byte modes)
The machine supports both nibble (AT) and byte (Bi-directional) mode
parallel ports. If your PC supports byte mode, scanning and fax reception
will be at a faster speed. To verify or change the parallel port mode, please
check your system BIOS in the CMOS Setup or contact your computer
manufacturer for assistance.
Some older PC models support only nibble mode. Generally, newer
models support both nibble and byte modes.

Machine Connect Failure or Bi-Directional
Communication Error
Recently, some printers have included a function that shows the printer
status on the PC display. Such printers use the bi-directional
communication parallel port between the printer and the PC.  Our
machines have a bi-directional parallel port function. Since Windows
¨
3.1x does not support bi-directional communication on the parallel port,
each peripheral vendor has developed and supplied a bi-directional device
driver, which will be installed into Windows
¨ 3.1x.  If you install two or
more different bi-directional device drivers into Windows¨, they may
conflict with each other and cause problems.
Please make sure you have installed the Brother printer driver, by
executing SETUP.EXE from your CD-ROM drive, following the
instructions on the CD-ROM label. The bi-directional communication may
be disabled when the driver is installed from the Add menu in ÒPrintersÓ
of the Control Panel. Please restart Windows
¨.
Remove the conflicting situation caused by one of the following printer
drivers. Review the following sections that apply to any additional printer
drivers you may have installed into your Windows

HP LaserJet series II, IID, IIP, IIP+, III, IIID or IIIP:
If Microsoft Windows¨ Printing System is used for the above models, you
must  modify the Òwin.iniÓ file in the Windows¨ directory to turn the
machineÕs bi-directional function off.
We recommend that you do a back-up before you modify the WIN.INI or
SYSTEM.INI files, just in case.
Open the Òwin.iniÓ file using the ÒNotepadÓ application. Look for the
following statement in the [spooler] section:
[spooler]
QP.LPT1 = wpsljqp.dll
Then disable this function, by adding a semicolon at the beginning of the
above sentence as follows:

You must restart Windows¨ to make these modifications effective.
These modifications disable the printer status reporting on your PC;
however, you will be able to use the machine without further problems.
