    the power cord from the electrical 
    socket. 
    bLift the document cover (1).
    Clean the white plastic surface (2) and 
    scanner glass (3) underneath it with a 
    soft lint-free cloth moistened with water.
     
    c(DCP-7040 and DCP-7045N) In the 
    ADF unit, clean the white bar  (1) and the 
    scanner glass strip (2) underneath it 
    with a soft lint-free cloth moistened with 
    water.
     
    dPlug the machine’s power cord back into 
    the electrical socket first, and then

    machine’s power switch.
    Note
    In addition to cleaning the scanner glass 
    and glass strip with a soft lint-free cloth 
    moistened with water, run your finger tip 
    over the glass to see if you can feel 
    anything on it. If you feel dirt or debris, 
    clean the glass again concentrating on 
    that area. You may need to repeat the 
    cleaning process three or four times. To 
    test, make a copy  after each cleaning.

    B
    Replacing the consumable itemsB
    You will need to replace the consumable items wh en the machine indicates that the life of the 
    consumable is over.
    Note
    • Discard used consumable items according to local regulations. (See  EU Directive 2002/96/EC 
    and EN50419  on  page  39.) If you have questions, call  your local waste disposal office. Be sure 
    to reseal the consumable it ems tightly so that the mate rial inside does not spill.
    • We recommend placing used consumable items  on a piece of paper to prevent accidentally 
    spilling or scattering  the material inside.
    • If you use paper that is not a direct equiv alent for the recommended paper, the life of 
    consumable items and machine parts may be reduced.
     
    Replacing a toner cartridgeB
    The High Yield toner cartridges can print 
    approximately 2,600 pages
     1 and the 
    Standard toner cartridges can print 
    approximately 1,500 pages
     1. Actual page 
    count will vary depending on your average 
    type of document (i.e., standard letter, 
    detailed graphics).  
    When a toner cartridge is running low, the 
    LCD shows  Toner Low . 
    1Approx. cartridge yield is declared in accordance 
    with ISO/IEC 19752.
    Note
    It is a good idea to keep a new toner 
    cartridge ready for use when you see the 
    Toner Low warning.

    Brother machines are designed to work 
    with toner of a particular specification and 
    will work to a level of  optimum performance 
    when used with genuine Brother toner 
    cartridges (TN-2110/TN-2120). Brother 
    cannot guarantee this optimum 
    performance if toner or toner cartridges of 
    other specifications are used. Brother does 
    not therefore recommend the use of 
    cartridges other than genuine Brother 
    cartridges with this ma chine, or the refilling 
    of empty cartridges with toner from other 
    sources. If damage is caused to the drum 
    unit or other part of this machine as a result 
    of the use of toner or toner cartridges other 
    than genuine Brother products due to the 
    incompatibility or lack of  suitability of those 
    products with this machine, any repairs 
    required as a result may not be covered by 
    the warranty. 
     
     
    Unpack the toner cartridge just before you 
    put it in the machine.  If a toner cartridge is 
    left unpacked for a long time, the toner life 
    will be shortened.
     
    Note
    Be sure to seal up the used toner cartridge 
    tightly in a suitable bag so that toner 
    powder does not spill  out of the cartridge.
     
    dUnpack the new toner cartridge. Hold 
    the cartridge level with both hands and 
    gently rock it from side  to side five or six 
    times to spread the toner evenly inside 
    the cartridge.
     
    ePull off the protective cover.

    lever will lift automatically.
     
    CAUTION 
    Make sure that you put in the toner 
    cartridge correctly or it may separate from 
    the drum unit.
