    CONSUMABLES AND MAINTENANCE
    This section deals with the replacement of the toner cartridge and 
    image drum and general maintenance.
    CONSUMABLE ORDER DETAILS
    *typical for continuous printing
    Please always use genuine consumables. 
    TONER CARTRIDGE LIFE
    How long your toner cartridge lasts depends on the print density; 
    the percentage of the page that prints black. A typical letter has 
    3% to 5% print density; graphics usually have higher density. 
    Higher print density means toner is used up faster. At 5% print 
    density, a standard toner cartridge will print an average of 3,000 
    pages. Remember, this is only an average: actual results may 
    vary.
    The first toner cartridge installed in a new printer has to fill the 
    image drum reservoir and saturate the developing roller with 
    toner. The first standard toner cartridge normally produces about 
    1,000 pages after installation.

    WHEN TO REPLACE THE TONER CARTRIDGE
    B4400, B4400N
    Replace the toner cartridge after Toner Low displays in the printer 
    Status Monitor. Also, the Error LED indicator slowly blinks when 
    toner is low. After Toner Low displays, the printer will print about 
    100 more pages then display Toner Empty and stop printing. 
    Printing will resume after a new toner cartridge has been 
    installed.
    B4600, B4600N, B4600PS, B4600NPS
    When the toner is running low, TONER LOW is displayed in the 
    operator panel LCD. If printing continues without replacing the 
    toner cartridge, CHANGE TONER is displayed and printing is 
    cancelled. Printing will resume after a new toner cartridge has 
    been installed.
    REPLACING THE TONER CARTRIDGE
    It is recommended that you clean the LED array at the same time 
    as you change the toner cartridge.
    The toner used in this printer is a very fine dry powder contained 
    in the toner cartridge.
    Have a sheet of paper handy so that you have somewhere to 
    place the used cartridge while you install the new one.
    Dispose of the old cartridge responsibly, inside the pack that the 
    new one came in. Follow any regulations, recommendations, etc., 
    which may be in force concerning waste recycling.
    If you do spill any toner powder, lightly brush it off. If this is not 
    enough, use a cool, damp cloth to remove any residue. Do not 
    use hot water, and never use solvents of any kind. They will make 
    stains permanent.
    WARNING!
    If you inhale any toner or get it in your eyes, drink a 
    little water or bathe your eyes liberally in cold water. 
    Seek medical attention immediately.

    Switch off the printer and allow the fuser to cool for about 
    10 minutes before opening the top cover.
    1.Press the top cover release button and open the printer’s 
    top cover fully.
    2.Pull the coloured lever on the right side of the toner 
    cartridge towards the front of the printer to close the 
    cartridge then remove the used toner cartridge.
    3.Follow the installation instructions on or inside the box 
    containing the new toner cartridge to install the new 
    cartridge.
    4.Gently wipe the LED array surface with the LED lens 
    cleaner that came with the new toner cartridge or soft 
    tissue.
    5.Close the top cover and press it down to latch it closed.
    IMAGE DRUM LIFE
    The life of an image drum depends on a number of factors, 
    including temperature and humidity, the type of paper used, and 
    the number of pages per job.
    The image drum should last approximately 25,000 pages 
    continuous printing. This number is approximate because 
    different numbers of pages are printed each time and the 
    environmental conditions and the paper type used may vary.
    WHEN TO REPLACE THE IMAGE DRUM
    B4400, B4400N
    When the drum reaches 90% of its life, a CHANGE DRUM 
    message is displayed in the printer Status Monitor. Also, the Error 
    LED indicator blinks fast when the image drum requires 
    changing. Change the image drum when the print becomes faint 
    or begins to deteriorate.
    WARNING!
    If the printer has been powered on, the fuser may be 
    hot. This area is clearly labelled. Do not touch.

    CAUTION!
    The green image drum surface at the base of the 
    cartridge is very delicate and light sensitive. Do not 
    touch it and do not expose it to normal room light for 
    more than 5 minutes. If the drum unit needs to be out 
    of the printer for longer than this, please wrap the 
    cartridge inside a black plastic bag to keep it away 
    from light. Never expose the drum to direct sunlight 
    or very bright room lighting. Always hold the image 
    drum unit by the ends or from the top.

    TROUBLESHOOTING
    STATUS AND ERROR MESSAGES
    Your printer has been designed to give you helpful status 
    feedback not only during normal operation but also if a printing 
    problem occurs so that you can take appropriate corrective 
    action.
    B4400, B4400N
    Both status and error messages are displayed in your chosen 
    language in the Status Monitor, error messages being 
    accompanied by the appropriate flashing of the Error indicator. 
    You can set the Status Monitor to pop up on your computer 
    screen when an alert condition occurs from the Preferences tab 
    in the Status Monitor.
    B4600, B4600N, B4600PS, B4600NPS
    The LCD on the printer operator panel provides the self-
    explanatory status and error messages in your chosen language. 
    Error messages are accompanied by the Ready indicator being 
    extinguished.
    PAPER JAMS
    Provided that you follow the recommendations in this guide on 
    use of print media, and you keep the media in good condition 
    prior to use, your printer should give years of reliable service. 
    However, paper jams occasionally do occur, and this section 
    explains how to clear them quickly and simply.
    Jams can occur due to paper misfeeding from a paper tray or at 
    any point on the paper path through the printer. When a jam 
    occurs, the printer immediately stops, and the operator panel 
    informs you of the event. If printing multiple pages (or copies), 
    do not assume that having cleared an obvious sheet that others 
    will not also be stopped somewhere along the path. These must 
    also be removed in order to clear the jam fully and restore normal 
    operation.

    The printer may experience a paper jam in one of three areas. 
    >INPUT JAM - paper has failed to leave the selected feed 
    tray and enter the internal paper path of the printer. A 
    typical message indicates a paper jam and identifies the 
    tray to check.
    >FEED JAM - paper has entered the printer but failed to 
    reach the exit. A typical message indicates a paper jam 
    and advises you to open the top cover for access.
    >EXIT JAM - paper has reached the exit but has failed to 
    exit completely from the printer. A typical message 
    indicates an exit jam and advises you to open the top 
    cover for access.
    INPUT JAM
    1.Remove the paper tray from the printer.
    2.Remove any crumpled or folded paper.
    3.Remove any paper from the underside of the printer.
    4.Replace the paper tray. 
    After successful removal of any damaged or misfed paper, the 
    printer should continue printing.
    FEED JAM OR EXIT JAM
    1.Remove the tray and clear any misfed sheets as given 
    above.
    2.Open the top cover.
    WARNING!
    The fuser area will be hot. This area is clearly marked. 
    Do not touch it.

    3.Carefully lift out the image drum, complete with the toner 
    cartridge. Be careful not to touch or scratch the green 
    drum surface.
    4.Remove any jammed sheets from the paper path.
    5.Re-install the image drum complete with toner cartridge, 
    ensuring that it correctly locates into the slots on each 
    side of the printer.
    6.Close the top cover and press down to latch it closed.
    7.The printer will warm up and commence printing when 
    ready. The page lost through the jam will normally be 
    reprinted.
    CAUTION!
    Never expose the image drum unit to light for more 
    than 5 minutes. Never expose the image drum unit to 
    direct sunlight. Always hold the image drum unit by 
    the ends or from the top. Never touch the surface of 
    the green drum inside the image drum unit.
    NOTE
    If the edge of the jammed paper protrudes (or can be seen) 
    from the exit, reinstall the image drum, close the top cover 
    and switch the printer on. Remove the jammed paper from 
    the exit when the exit roller begins rotating after a few 
    seconds after switching on. However, if the jammed paper 
    cannot be removed, contact a service representative.
