    Difficulty with Operation
    If you think there is a problem with the machine, check the table below and follow the 
    troubleshooting tips.
    DIFFICULTYSUGGESTIONS
    General Printing Difficulties
    The machine does not print. Make sure the machine is turned on. The toner cartridge and drum 
    unit are installed properly. The interface cable is securely connected 
    between the machine and computer. Check to see if LCD is showing 
    an error message.
    The machine prints 
    unexpectedly or it prints 
    garbage.Switch off. Make sure your application software is correctly set up 
    to use the machine by checking the primary settings in your 
    application software.
    The machine prints the first 
    couple of pages correctly, 
    then some pages have text 
    missing.Your computer is not recognizing the printer’s “input buffer full” 
    signal. Please make sure you connect the printer cable correctly.
    The machine cannot print full 
    pages of a document. A OUT 
    OF MEMORY error 
    message occurs.Reduce the printer resolution. Reduce the complexity of your 
    document and try again. Reduce the graphic quality or the number 
    of font sizes within your application software. Expand the printer 
    memory with the optional memory board. (See Memory Board, 
    page 94.)
    My headers or footers appear 
    when I view my document on 
    the screen but do not show up 
    when I print them.Most laser printers have a restricted area that will not accept print. 
    Usually these are the first two lines and last two lines, leaves 62 
    printable lines. Adjust the top and bottom margins in your document 
    to allow for this.
    Windows
    ® Setup Printing Difficulties
    I cannot print from my 
    application software.Make sure the Windows
    ® printer driver is installed and you select it 
    in your application software.
    Software Difficulties
    “MFC Connect Failure”If the 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 Centre chapter. (See How to Turn Off AutoLoad, page 47.) 
    Paper Handling Difficulties
    The machine does not load 
    paper. The LCD shows 
    CHECK PAPER or PAPER 
    JAM Check to see if the CHECK PAPER or PAPER JAM message 
    appears on the LCD. If so, the paper tray may be out of paper. If it 
    is empty, load a new stack of paper into the paper tray. If there is 
    paper in the paper tray, make sure it is straight. If the paper is curled, 
    you should straighten it. Sometimes it is helpful to remove the 
    paper, turn the stack over and put it back into the paper tray. Reduce 
    the amount of paper in the paper tray, then try again. Check the 
    manual feed mode is not selected in the printer driver. (See Paper 
    Source, page 32.)

    Copy Quality Difficulties
    Vertical streaks appear in 
    copiesSometimes you may see vertical streaks on your copies. Either the 
    scanner or the primary corona wire for printing is dirty. Clean them 
    both.
    Print Quality Difficulties
    Printed pages are curled.Thin Paper (60-69 g/m2) can cause this problem. Make sure you 
    select the Paper Type that suits the paper in your paper tray. (See 
    Paper Type, page 18 and 22 and Media Type, page 32.)
    Printed pages are smeared.Rough surfaces or thick media can cause “smeared pages”—OR— 
    “the toner to smear”. Make sure you select the correct Paper Type 
    that suits the paper in your paper tray. (See Paper Type, page 18 and 
    22 and Media Type, page 32.)
    Printouts are too dark or light Adjust the print conditions by setting the Print Density function, it 
    has been factory set to the middle position. (See Setting the Print 
    Density, page 11.)
    Printed pages contain white 
    stripes.
    White Stripes or Faint Images
    You may fix this by wiping the scanner windows with a clean soft 
    cloth. (See Regular Maintenance, page 81 and Cleaning the Printer, 
    page 82.) If you still see white stripes or faint images and the display 
    shows CHANGE DRUM SOON, replace the drum unit with a new 
    one.
    Printed pages are stained with 
    toner or have vertical stripes.
    Dark Stripes or Toner Stains
    Clean the machine’s interior and the primary corona wire of drum 
    unit. (See Regular Maintenance, page 81 and Cleaning the Drum 
    Unit, page 83.) Make sure that the tab of the corona wire is at the 
    home position. If after cleaning, you still see dark stripes or toner 
    stains and the display shows CHANGE DRUM SOON, replace the 
    drum unit with a new one.
    Printed pages have white 
    spots in black text and 
    graphic areas.
    White Spots
    Make sure that you use paper that meets the specifications. (See 
    Acceptable Paper, page 29.) Rough surface or thick media can 
    cause the problem. If you still see white spots and the display shows 
    CHANGE DRUM SOON, replace the drum unit with a new one.
    Toner scatters and stains the 
    printed page.
    Scattering Toner
    Adjust the print conditions by setting the Print Density function. 
    (See Setting the Print Density, page 11.) Clean the machine’s 
    interior. (See Regular Maintenance, page 81 and Cleaning the 
    Drum Unit, page 83.) Make sure that you use paper that meets 
    specifications. (See Acceptable Paper, page 29.) If you still have 
    scattered toner and the display shows CHANGE DRUM SOON, 
    replace the drum unit with a new one.

    The whole page is printed 
    black.
    Black Page
    Clean the machine’s interior and the primary corona wire of the 
    drum unit. (See Regular Maintenance, page 81  and Cleaning the 
    Drum Unit, page 83.) Also, do not use heat-sensitive paper as it will 
    cause this problem. After cleaning, if the printed pages are still 
    black or the display shows CHANGE DRUM SOON, replace the 
    drum unit with a new one. The drum unit may be damaged.
    Nothing is printed on the 
    page.
    White page
    Make sure that the toner cartridge is not empty. If the toner cartridge 
    is empty, replace the toner cartridge. (See Replacing the Toner 
    Cartridge, page 84.)
    Printed pages are marked 
    regular intervals.
    Example of Regular Marking
    Markings may disappear by themselves. Try copying at multiple 
    pages to clear this problem. Markings may occur if the machine has 
    not been used for a long time. A possible cause is that the surface of 
    the drum is marked or damaged by excessive exposure to light. In 
    this case, replace the drum unit with a new one.
    Printed pages are blurred at 
    the centre or at either edge.
    Blurred Page
    Certain environmental conditions such as humidity, high 
    temperatures, etc. may cause this condition to occur. Make sure the 
    machine is placed on a flat, horizontal surface. Remove the drum 
    unit with the toner cartridge installed. Try rocking them from side 
    to side. You may clear a blurred page by wiping the scanner window 
    with a clean soft cloth. (See Regular Maintenance, page 81.) If a 
    blurred page occurs after cleaning and the display shows CHANGE 
    DRUM SOON, replace the drum unit with a new one.
    Ghost images appear on 
    printed page.
    Ghost Images
    Adjust the print conditions by changing the Print Density setting. 
    (See Setting the Print Density, page 11.)—OR—Rough surfaces or 
    thick media can cause a ghost image. Make sure you select the Paper 
    Type that suits the paper in your paper type.  (See Paper Type, page 
    18 and 22 and Media Type, page 32.)
    The drum unit is a consumable and it is necessary to replace it periodically.

    Replacing the Toner Cartridge
    The machine can print up to 6,000 pages using a high yield toner cartridge (TN-6600). When the 
    toner cartridge is running low, the display shows CHANGE TONER. The machine is supplied with 
    a standard toner cartridge (TN-6300) that must be replaced after approximately 3,000 pages. Actual 
    page count will vary depending on your average document type.
    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 
    with Brother dealer for 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.
    It is recommended that you clean the machine when you replace the toner.
    Toner Empty Indicator
    When the toner cartridge is running low, the display shows CHANGE TONER and the Toner 
    Empty LED on the control panel flashes on and off to indicate the toner is low.
    The Toner Empty LED light stays on and the display shows TONER EMPTY to indicate that the 
    toner is empty. Once this indication appears, the machine will not resume printing until you have 
    installed a new toner cartridge.
    Steps for Replacing Toner Cartridge
    After you have just used the machine, some internal parts of the machine 
    will be extremely HOT! So, never touch the shaded parts shown in the 
    illustration below.
