    Color Matching Problems
    Colors on your monitor are different from those in the original 
    image.
    Try one or more of these solutions: 
    ❏Check the image settings of your scanner software, especially the data format (bits, 
    pixel and color), gamma correction, and color correction. Try different combinations of 
    these settings.
    ❏Check the color matching and color management capabilities of your computer, display 
    adapter, and software. Some computers can change the color palette to adjust the 
    colors on your screen. See your software and hardware manuals for details. 
    ❏Use the color management system for your computer: ICM for Windows, or ColorSync 
    for Macintosh. For Windows, add a color profile that matches your monitor.
    ❏Exact color matching is very difficult. Check your software and monitor documentation 
    for information on color matching and calibration.

    Document Feeder during scanning.
    Check if the ADF unit or ADF cover is closed firmly.
    You cannot scan using the Auto Document Feeder.
    Try one or more of the following solutions:
    ❏Make sure either the Office Mode or the Professional Mode is selected in EPSON Scan.
    ❏Make sure ADF-Single-sided or ADF-Double-sided is selected as the document 
    source in EPSON Scan.
    ❏If the Auto Document Feeder is open, close it and then try again. If the Auto Document 
    Feeder is already open while you are scanning, remove any jammed paper; reload any 
    document not yet scanned and then restart EPSON Scan.
    ❏Remove any jammed paper, and then reload the document and restart EPSON Scan.

    on page 36.
    ❏Make sure the original is loaded correctly. See Setting Originals to Copy on page 197.

    Copy Quality Problems
    Printout is not fine enough

    document  table:  Place the original face-down 
    on the document table.
    Cause What to do
     
    						
    							Copying Problems326
    The information on the back side or background color is printed on 
    the copy
    Copies are blank, or images are missing or faded
    Try one or more of the following solutions.
    ❏The sealing tape might still be in the toner cartridge. Remove the toner cartridge, pull 
    out the sealing tape, and reinstall the toner cartridge. See Replacing a toner cartridge 
    on page 278.
    ❏If the toner cartridge is low on toner, the copies will be faded. Replace the toner 
    cartridge with a new one. 
    You may not be using the correct type of 
    paper for copying.The available paper types for copying are not the 
    same as that for printing. When you copy an original, 
    use the correct type of paper. Depending on the 
    paper source, the following paper types are 
    available.
    MP tray:
    Plain paper, EPSON Color Laser Paper, Letterhead, 
    Recycled paper, Colored paper, Transparencies, 
    Labels 
    Optional paper cassette:
    Plain paper, EPSON Color Laser Paper, Letterhead, 
    Recycled paper, Colored paper
    Coated paper, thick paper, and special paper such 
    as postcard or envelopes are not available for 
    copying.
    Cause What to do
    The original is almost transparent or extremely 
    thin.When you copy a thin double-sided original, the 
    information on the back side of the original may be 
    printed on the copy. Using black paper or an 
    underlay beneath the original may solve the 
    problem.
    The copy setting may not be matched with 
    the original.Select the settings that match the original and make 
    a copy. When the settings are made correctly, the 
    back side is not copied as the brightest part is 
    adjusted to white. This also removes the yellowish 
    color in the background.
    If these problems cannot be solved even if the 
    settings are made correctly, select Text for 
    document type or set the contrast to a positive 
    value. 
     
    						
    							Copying Problems327
    ❏The accuracy of the copy depends on the quality and size of the original. Try adjusting 
    the contrast with the product. If your original is too light, the copy might not be able to 
    compensate, even if you adjust the contrast.
    ❏If the original have a colored background, images in the foreground might blend too 
    much or the background might appear in a different shade. Adjust the settings before 
    copying or enhance the image after it has been copied.
    Improving copy quality
    Try one or more of the following solutions.
    ❏Copy from the document table. This will produce a higher quality copy than copying 
    from the Auto Document Feeder.
    ❏Use quality originals.
    ❏Load the media correctly. If the media is loaded incorrectly, it might skew, causing 
    unclear images and problems with the OCR application. 
    ❏Open or close the MP tray to accommodate the copy job. If you are copying to standard 
    weight media, use the paper cassette. If you are copying to heavy media, use the MP 
    tray. 
    ❏If your product frequently feeds more than one page at a time, replace the pickup roller.
    ❏Use or make a carrier sheet to protect your originals.
    Completely blank pages are output
    Try one or more of the following solutions.
    ❏The original might have been loaded upside down. In the Auto Document Feeder, load 
    the original with the short edge forward and the side to be scanned facing up.
    ❏If you are getting blank pages when scanning from the document table, make sure the 
    original is loaded correctly. Place the original face-down on the document table with the 
    top left corner of the document located in the lower right corner of the glass.
    ❏The media might not meet EPSON’s media specifications (e.g., the media is too moist 
    or too rough).
    ❏The toner might be out.
    ❏The tape might not have been removed from the toner cartridge.

    High quality color copy stops halfway
    When you make a continuous high quality (600 dpi) color copy with the default memory 
    (128 MB), the product may not work properly because of insufficient memory. We 
    recommend adding an memory module so that the total memory size is 256 MB or higher.
