    The printer 
    prints, but 
    the text is 
    wrong, 
    garbled, or 
    incomplete. The printer cable 
    is loose or 
    defective.
    Disconnect and reconnect the 
    printer cable. Try a print job that 
    you have already printed 
    successfully. If possible, attach 
    the cable and printer to another 
    computer and try a print job 
    that you know works. Finally, 
    try a new printer cable.
    The wrong printer 
    driver was 
    selected. Check the application’s printer 
    selection menu to ensure that 
    your printer is selected.
    The software 
    application is 
    malfunctioning. Try printing a job from another 
    application.
    The operating 
    system is 
    malfunctioning. If printing from Windows (any 
    version), exit to a DOS prompt 
    and verify functionality with the 
    following command: At a 
    C:\ 
    prompt, type  Dir LPT1, and 
    press 
    OK. (This assumes you 
    are connected to LPT1.)
    Exit Windows and reboot the 
    computer. Turn the printer off 
    and then back on again.
    If you are under 
    the DOS 
    environment, the 
    font setting for 
    your machine 
    may be set 
    incorrectly. Change the font setting. See 
     page 2.7
    Pages print, 
    but are 
    blank. The toner 
    cartridge is 
    defective or out of 
    toner.
    Redistribute the toner 
    cartridge. See page 8.3.
    If necessary, replace the toner 
    cartridge. See page 8.3.
    The file may have 
    blank pages. Check the file to ensure that it 
    does not contain blank pages.
    Some parts, such 
    as the controller 
    or the board, may 
    be defective. Contact a service 
    representative.
    The printer 
    does not 
    print PDF file 
    correctly. 
    Some parts 
    of graphics, 
    text, or

    are missing. Incompatibility 
    between the PDF 
    file and the 
    Acrobat products.
    Printing the PDF file as an 
    image may solve this problem. 
    Turn on 
    Print As Image  from 
    the Acrobat printing options.

    Solving print quality problems
    Dirt inside of the printer or improper paper loading may reduce print 
    quality. See the table below  to troubleshoot problems. 
    ConditionSuggested solutions
    Light or faded 
    print If a vertical white streak or faded area appears on 
    the page:
    • The toner supply is low. You may be able to 
    temporarily extend the toner cartridge life. See 
    page 8.3. If this does not improve print quality, 
    install a new toner cartridge.
    • The paper may not meet paper specifications  (for example, the paper is too moist or too 
    rough). See page 5.3.
    • If the entire page is light, the print resolution  setting is too light or toner save mode is on. 
    Adjust the print resolution and toner save mode 
    in the printer properties. See the  Software 
    Section .
    • A combination of faded or smeared defects 
    may indicate that the printer needs cleaning. 
    See page 8.1.
    • The surface of LSU may be dirty. Clean the 
    LSU. See page 8.1.
    To n e r  s p o ts • The paper may not meet  specifications (for 
    example, the paper is to o moist or too rough). 
    See page 5.3.
    • The transfer roller or paper path may be dirty. 
    See page 8.1.
    Dropouts If generally rounded, faded areas occur randomly 
    on the page:
    • A single sheet of paper may be defective. Try 
    reprinting the job.
    • The moisture content of the paper is uneven or  the paper has moist spots on its surface. Try a 
    different brand of paper. See page 5.3.
    • The paper lot is bad. The manufacturing  processes can cause some areas to reject 
    toner. Try a different kind or brand of paper.
    • The toner cartridge may be defective. See  “Vertical repetitive defects” on the next page.
    • If these steps do not  correct the problems, 
    contact a service representative.

    Vertical lines
    If black vertical streaks appear on the page:
    • The drum inside the toner cartridge has probably been scratched. Install a new toner 
    cartridge. 
    Gray 
    background If the amount of background shading becomes 
    unacceptable, the procedures below may fix the 
    problem.
    • Change to lighter weight pages. See page 5.3.
    • Check the printer’s envi
    ronment; very dry (low 
    humidity) or high humidity (higher than 80% 
    RH) conditions can increase the amount of 
    background shading.
    • Remove the old toner cartridge and install a  new one. See page 8.3.
    Toner smear • Clean the inside of the printer. See page 8.1.
    • Check the type and quality. See page 5.2.
    • Remove the toner cartridge and install a new 
    one. See page 8.3.
    Ve r t ic a l 
    repetitive 
    defects If marks repeatedly appear on the printed side of 
    the page at even intervals:
    • The toner cartridge may be damaged. If a 
    repetitive mark occurs on the page, print a 
    cleaning sheet several times to clean the 
    cartridge; see page 8.2.  After the printout, if 
    you still have the same problems, install a new 
    toner cartridge. See page 8.3.
    • Parts of the printer may have toner on them. If  the defects occur on the back of the page, the 
    problem will likely correct itself after a few more 
    pages.
    • The fusing assembly may be damaged.  Contact a service representative.

    Background 
    scatter Background scatter results from bits of toner 
    distributed on the printed page. 
    • The paper may be too damp. Try printing with a 
    different batch of paper. Do not open packages 
    of paper until necessary  so that the paper does 
    not absorb too much moisture.
    • If background scatter occurs on an envelope,  change the printing layout to avoid printing over 
    areas that have overlapping seams on the reverse 
    side. Printing on seams can cause problems.
    • If background scatter covers the entire surface area of a printed page, adjust the print 
    resolution through your software application or 
    via the printer properties window.
    Misformed 
    characters • If characters are improperly formed and 
    producing hollowed images, the paper stock 
    may be too slick. Try a different paper. See 
    page 5.3.
    • If characters are improperly formed and  producing a wavy effect, the scanner unit may 
    need service. Verify that it also occurs on a 
    demo page (see page 2.6). For service, contact 
    a service representative.
    Page skew • Ensure that the paper is loaded properly.
    • Check the paper type and quality. See 
    page 5.2.
    • Ensure that the paper or other material is 
    loaded correctly and the guides are not too 
    tight or too loose against the paper stack.
    Curl or wave • Ensure that the paper is loaded properly.
    • Check the type and quality. Both high 
    temperature and humidity can cause paper 
    curl. See page 5.2.
    • Turn over the stack of paper in the tray. Also try  rotating the paper 180° in the tray.
    • Try printing to the rear cover (face-up).
    Wrinkles or 
    creases • Ensure that the paper is loaded properly.
    • Check the paper type and quality. See 
    page 5.2.
    • Open the rear cover and  try printing to the rear 
    cover (face-up).
    • Turn over the stack of paper in the tray. Also try  rotating the paper 180° in the tray.

    Common Linux problems
    ConditionSuggested solutions
    The print doesn’t 
    print. • Check if the printer driver is installed in your 
    system. Open Unified Dr iver Configurator 
    and switch to the Printers tab in Printers 
    configuration window to  look at the list of 
    available printers. Make sure that your 
    machine is displayed  on the list. If not, 
    please, invoke Add new printer wizard to set 
    up your device. 
    • Check if the printer is  started. Open Printers 
    configuration and select your machine on 
    the printers list. Look  at the description in 
    the Selected printer pane. If its status 
    contains “(stopped)” string, please, press 
    the  Start  button. After that normal operation 
    of the printer should be restored. The 
    stopped status might be activated when 
    some problems in printing occurred.
    I encounter error 
    “Unable to open 
    MFP port device 
    file!” when printing 
    a document. Please avoid changing print job parameters 
    (via LPR GUI, for example) while a print job is 
    in progress. Known versions of CUPS server 
    break the print job whenever print options are 
    changed and then try to restart the job from 
    the beginning. Since Unified Linux Driver 
    locks port while printing, the abrupt 
    termination of the driver
     keeps the port locked 
    and therefore unavailable for subsequent print 
    jobs. If this situation  occurred, please, try to 
    release the port.
    The printer does

    Printing the PDF file as an image may solve 
    this problem. Turn on 
    Print As Image from 
    the Acrobat printing options. 
    Note: it will take longer to print when you print

    10 Installing accessories
    Your printer is a full-featured laser  printer that has been optimized to 
    meet most of your printing needs.  Recognizing that each user may have 
    different requirements, however, Samsung makes several accessories 
    available to enhance the printer’s capabilities.
    This chapter includes:
    • Precautions when installing accessories
    • Installing a memory DIMM
    • Installing a wireless network interface card
    Precautions when installing accessories
    Disconnect the power cord: 
    Never remove the control board cover while the power is being supplied.
    To avoid the possibility of an elec trical shock, always disconnect the 
    power cord when installing or removing ANY internal or external 
    accessories.
    Discharge static electricity: 
    The control board and internal accesso ries (network interface card and 
    memory DIMM) are sensitive to static  electricity. Before installing or 
    removing an internal accessories, di scharge static electricity from your 
    body by touching something metal, such as the metal back plate on any 
    device plugged into a grounded power source. If you walk round before 
    finishing installation, discharge any static electricity once again.
    Installing a memory DIMM
    Your printer has a dual  in-line memory module (DIMM) slot. Use this 
    DIMM slot to install additional memory.
    The ML-3050 has 16 MB of memory which can be expanded to 272 MB. 
    The ML-3051N and ML-3051ND have 64 MB of memory which can be 
    expanded to 320 MB. 
    For order information for optional memory DIMMs, see page 7.1.
    1 Turn the printer power off and unplug all cables from the printer. 2
    Grasp the control board cover and slide toward you to open it.
    3 Completely open the latch on each side of the DIMM slot.
    4 Take out a new memory DIMM from the plastic bag.
    5 Holding the memory DIMM by the  edges, align the notches on the 
    memory DIMM with the grooves  on the memory DIMM slot.
