    You must modify the Òwin.iniÓ and Òsystem.iniÓ files in the Windows¨
    directory to turn off the printers bi-directional function.
    We recommend that you backup the WIN.INI and SYSTEM.INI files
    before you modify them.
    Open the Òwin.iniÓ file using the ÒNotepadÓ application. Look for the
    following statement in the [windows] section:
    [windows]
    run=C:/WINDOWS/SYSTEM/WPSIOMON
    Then disable this function, by adding a semicolon at the beginning of the
    above sentence as follows:
    [windows]
    ;run=C:/WINDOWS/SYSTEM/WPSIOMON
    Look for the following statement in the [spooler] section:
    [spooler]
    QP.LPT1=wpslbq.dll
    Then disable this function, by adding a semicolon at the beginning of the
    above sentence as follows:
    [spooler]
    ;QP.LPT1=wpslbq.dll
    Then, open the Òsystem.iniÓ file using the ÒNotepadÓ application. Look
    for the following statement in the [386Enh] section:
    [386Enh]
    device=wpscomd.386
    device=wpsljvpd.386
    :
    :
    WPSLPT1=1
    Then disable this function, by adding a semicolon at the beginning of
    above sentences as follows:
    [386Enh]
    ;device=wpscomd.386
    ;device=wpsljvpd.386
    :
    :
    ;WPSLPT1=1
     
    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.

    Routine Maintenance
    Keep your machine in optimum condition by cleaning it on a regular basis.
    It is a good idea to clean the drum unit during this routine. Avoid using
    thinners or other organic solvents and do not use water.
    Cleaning the Document Scanner
    1Unplug the telephone line and then the power cord.
    When you reconnect these lines later, connect the power cord first, then
    the telephone line.
    2Lift the control panel cover.
    3Clean the white bar and glass
    cover under the white bar.
    Moisten a small, clean, soft,
    lint-free cloth with isopropyl

    tab from right to left several times.
    2Return the tab and snap it into the home position (t).

    (See Replacing the Drum Unit on page 17-26.)
    4Close the front cover.
    5Plug in the power cord first, then the telephone cord.
    Replacing the Toner Cartridge
    The machine can print up to 6,000 pages using a high yield toner
    cartridge.  When the toner cartridge is running low, the display shows
    TONER LOW.  The machine is supplied with a standard toner cartridge
    that must be replaced after approximately 3,000 pages.  Actual page count
    will vary depending on your average document type (i.e., standard letter,
    detailed graphics).
    It is a good idea to keep a new toner cartridge ready for use when you see
    the toner low warning.
    Discard the used toner cartridge according to local regulations.  If you are
    not sure of them, consult Brother Customer Service.  Be sure to seal the
    toner cartridge tightly so toner powder does not spill out of the cartridge.
    When discarding used toner cartridges, keep them separate from domestic
    garbage.
    We recommend that you clean the machine when you replace the toner
    cartridge.
    Toner Empty Indicator
    When the toner cartridge is running low, the display shows TONER LOW
    and the Toner Empty icon on the control panel flashes on and off to
    indicate the toner is low.
                  
    DisplayToner Empty Icon
    The Toner Empty icon appears and the display shows TONER EMPTY.
    Once this icon appears, your machine will not resume printing until you
    install a new toner cartridge.

    							17 - 25TROUBLESHOOTING AND ROUTINE MAINTENANCE
    Caution
    nWait to unpack the toner cartridge until immediately before you install it
    into the machine.  If a toner cartridge is left unpacked for a long period of
    time, the toner life is shortened.
    nYou can use only a genuine Brother toner cartridge (TN-430 or TN-460),
    which is specially formulated to ensure top print quality.  Using another
    brand of toner cartridge may void your machineÕs warranty.
    4Gently rock the toner cartidge
    from side to side five or six
    times to distribute the toner
    evenly inside the cartridge.

    8Reinstall the drum unit
    and close the front cover.
    Replacing the Drum Unit
    The machine uses a drum unit to create print images on paper.  If the
    screen displays CHANGE DRUM SOON, the drum unit is near the end of
    its life and it is time to purchase a new one.
    Even if the display shows CHANGE DRUM SOON, you may be able to
    continue printing without having to replace the drum unit for a while.
    However, if there is a noticeable deterioration in the output print quality
    (even before CHANGE DRUM SOON is shown), then the drum unit
    should be replaced.  You should clean the machine when you replace the
    drum unit. (See page 17-22.)
    Caution
    When removing the drum unit, handle it carefully because it contains
    toner. If toner scatters and your hands or clothes get dirty, immediately
    wipe or wash with cold water.
    The drum unit is a consumable, and it is necessary to replace it
    periodically.  There are many factors that determine the actual drum life,
    such as temperature, humidity, type of paper and how much toner you
    use for the number of pages per print job, etc.  The estimated drum life is
    up to 20,000 pages. The actual number of pages your drum will print may
    be significantly less than these estimates.  Because we have no control
    over the many factors that determine the actual drum life, we cannot
    guarantee a minimum number of pages that will be printed by your drum.
    WARNING
    Just after you have used       
    HOT!the machine, some
    internal parts of the
    machine are extremely
    HOT! So please be
    careful.
