    Tray linking
    Tray linking enables the automatic linking feature for trays when the same size and type of media is loaded in multiple 
    sources. The printer automatically links the trays; when one tray is empty, media feeds from the next linked tray.
    For example, if the same size and type of media is loaded in tray 1 and tray 2, the printer selects media from tray 1 until it 
    becomes empty, and then the printer automatically feeds media from the next linked tray—tray 2.
    By linking both trays, a single source with a capacity of 1100 sheets is created.
    If the same size media in each tray is loaded, make sure the media is all the same type in order to link the trays.
    Once the selected trays are loaded with the same size and type of media, select the same Paper Type setting in the Paper 
    Menu for these sources.
    To disable tray linking, set the Paper Type to a unique value in each one of the trays. If all the trays do not have the same 
    type of media when they are linked, a job could mistakenly print on the wrong paper type.
    Using the duplex function (two-sided printing)
    Duplex printing (or two-sided printing) allows printing on both sides of a sheet of paper. Printing on both sides of paper 
    reduces printing costs.

    Media specifications
    For sizes that are acceptable for duplex printing, see Media sizes and support.
    Select Duplex from the printer driver to print individual duplex jobs.
    Duplex printing on letterhead
    When duplex (two-sided) printing on letterhead from the trays, load it with the logo face-up and entering the printer first.
    Using Duplex Bind
    When Duplex Bind printing is selected in the printer driver or Duplex Bind in the Finishing Menu, either long edge or short 
    edge binding must be selected, which are the values for this setting. The purpose of Duplex Bind is to define the way 
    duplexed pages are bound, and how the printing on the back of the sheet (even-numbered pages) is oriented in relation to 
    the printing on the front (odd-numbered pages).
    The two values for Duplex Bind are:
    Long Edge*
    The asterisk (*) 
    indicates this is 
    the factory default 
    setting.Assumes binding along the long end of the page (left edge for portrait orientation 
    and top edge for landscape orientation). The following illustration shows long-edge 
    binding for portrait and landscape pages:
    Short EdgeAssumes binding along the short edge of the page (top edge for portrait 
    orientation and left edge for landscape orientation). The following illustration 
    shows short-edge binding for portrait and landscape pages:

    							Avoiding jams

    Media specifications
    Avoiding jams
    Use appropriate print media (paper, transparencies, labels, and card stock) to help ensure trouble-free printing. See 
    Identifying media sources and specifications for more information.
    Note:Try a limited sample of any print media you are considering using with the printer before purchasing 
    large quantities.
    By selecting the appropriate print media and loading it properly, you can avoid most jams. See Loading standard trays 
    and optional trays, Loading the multipurpose feeder, or Loading the high capacity feeder for detailed tray loading 
    instructions.
    The following hints can help you avoid jams:
    Use only recommended print media.
    Do not overload the print media sources. Make sure the stack height does not exceed the maximum height 
    indicated by the stack line on the labels in the sources.
    Do not load wrinkled, creased, damp, or curled print media.
    Flex, fan, and straighten print media before you load it. If jams do occur with print media, try feeding one sheet at 
    a time through the multipurpose feeder.
    Do not use print media that you have cut or trimmed yourself.
    Do not mix print media sizes, weights, or types in the same print media source.
    Make sure the recommended print side is loaded in the source according to your simplex or duplex needs.
    Keep print media stored in an acceptable environment. See Storing media.
    Do not remove trays during a print job.
    Push all trays in firmly after loading them.
    Make sure the guides in the trays are properly positioned for the size of print media you have loaded. Make sure the guides 
    are not placed too tightly against the stack of print media.

    7Maintaining the printer
    Periodically, you need to complete certain tasks to maintain optimum print quality. These tasks are covered in this chapter.
    If several people are using the printer, you may want to designate a key operator to do the setup and maintenance of your 
    printer. Refer printing problems and maintenance tasks to this key operator.
    In the U.S., contact Lexmark at 1-800-539-6275 for information about Lexmark Authorized Supplies Dealers in your area. In 
    other countries or regions, visit the Lexmark Web site at www.lexmark.com or contact the place where you bought your 
    printer.
    Storing supplies
    Choose a cool, clean storage area for your printer supplies. Store supplies right side up in their original packaging until you 
    are ready to use them.
    Do not expose supplies to:
    Direct sunlight
    Temperatures above 35°C (95°F)
    High humidity (above 80%)
    Salty air
    Corrosive gases
    Heavy dust

    Maintaining the printer
    Determining the status of supplies
    The printer operator panel alerts you once a supply item or maintenance is required. You can also view the status of 
    supplies in your printer on the operator panel unless the printer is printing or in a busy state. The header or gray area at the 
    top of the display will indicate the printer is Ready and lets you know if any trays are low. Selecting Status / Supplies on 
    the display will open the Status / Supplies screen where you can view the status of the various trays and open the 
    supplies screen to view the current status of your toner cartridge.
    Conserving supplies
    Several settings in your application software or on the display let you conserve toner and paper. For more information on 
    changing these settings, see the Menus and Messages Guide.

    Ordering a toner cartridge
    When the [color] Low message appears, you should order a new print cartridge. You can print a few hundred pages after 
    the [color] Low message comes on. You need to have a new cartridge available when the current one no longer prints 
    satisfactorily.
    Note:Be sure to shake your new print cartridge before installing it into the printer to maximize its yield.
    The recommended print cartridges specifically designed for your printer are:
    When the message Replace Black Toner and Oil Coating Roll appears, the black cartridge is empty. Replace both the black 
    toner cartridge and the oil coating roll. Order Lexmark part number C92035X to replace the oil coating roll.
    Fuser and transfer belt
    Order a fuser or a transfer belt when Fuser Life Warning or Transfer Belt Life Warning appears on the display. 
    Replace the items when Replace Fuser or Replace Transfer Belt appear. Each kit contains all the items necessary to 
    replace either the transfer belt or the fuser. See the following table for the maintenance kit part number for your specific 
    printer. 
    Ordering a black photodeveloper or color photodevelopers
    We recommend ordering new photodevelopers when Black Photo Dev Life Warning or Color Photo Dev Life 
    Warning appears on the display.
