    IMPORTANT
    •Do not leave the machine inside a car for a long period of time; the temperature can 
    become very high or low.
    •Avoid rough roads; excessive vibration may damage the machine or adversely affect the 
    quality of your printouts.
    •Place a cover over the machine. Do not leave the machine in direct sunlight.

    This chapter describes the problems you might encounter when using the machine and their 
    remedies. It also explains what to do if you cannot solve the problem by yourself.
    Clearing Jams
    This section describes how to remove jammed paper.
    Removing Jammed Paper from Inside the Machine
    When print media jams inside the machine, the LCD displays .
    CAUTION
    There are some areas inside the machine and cartridge which are subject to 
    high voltages and high temperatures. Take adequate precaution when 
    performing internal inspections to avoid burns or electrical shock.
    NOTE
    When removing jammed paper from inside the machine, take care not to allow the toner 
    on the jammed paper to come into contact with your hands or clothing. If they become 
    dirty, wash them immediately with cold water. Washing with warm water will set the toner, 
    and make it impossible to remove the toner stains.

    1Open the front cover. 
    2Remove the cartridge.
    IMPORTANT
    •Remove watches and any bracelets or rings when touching the inside of the machine. 
    These items might be damaged if they come into contact with the parts inside the 
    machine.
    •To avoid possible damage to the machine, do not touch the pins (A) near the left end of 
    the transfer roller (B).
    •When removing the jammed paper, do not touch the transfer roller as its surface is very 
    delicate and susceptible to finger oil and scratches, which may lead to print deterioration.

    NOTE
    Do not expose the cartridge to light for more than 5 minutes. If necessary, put the 
    cartridge in its original protective bag or wrap it with a thick cloth to prevent exposure to 
    light.
    3Open the face up cover (A) and push down the green paper 
    release levers (B) on both sides of the face up paper output.
    4Hold both sides of the jammed paper and carefully move it inward, 
    then gently pull it out.
    5Roll the leading end of the paper outwards so that the printed 
    surface is on the inside of the roll, then gently pull the rolled up 
    paper out of the machine.

    6If the leading edge of the paper is visible but has not entered the 
    imaging area, pull the paper forwards and roll it inwards.
    IMPORTANT
    •Do not pull the jammed paper forward from the cassette. It may cause a machine 
    malfunction.
    •Do not pull the jammed paper upward; the toner on the paper will stain the machine and 
    cause a permanent reduction in print quality.

    7Gently pull the jammed paper between the output rollers until the 
    leading edge emerges from the machine.
    8Carefully pull the jammed paper straight out through the rollers.
    If the jammed paper is badly folded, similar to the folds of an accordion, ease the 
    jammed paper loose and then pull it out of the machine.

    close the face up cover.
    IMPORTANT
    •Be sure to push the paper release levers back to their original position. If the levers are 
    left pushed down, the paper jam error will not be resolved.
    •Never push down the paper release levers while printing. This could result in damage to 
    the fixing assembly.
    13Insert the cartridge back into the machine, then close the front 
    cover.

    IMPORTANT
    After you replace the cartridge and close the front cover, the machine should be ready for 
    operating. If the machine returns to the ready state for operating, troubleshooting has 
    been successful. If the machine does not return to the ready state for operating, confirm 
    that the paper release levers are pushed back to their original position, and check to see 
    that jammed paper is not left in the machine.
    14Insert the cassette to the machine.
    Removing Jammed Paper from the ADF

    2Widen the document guides until they stop, and remove the paper 
    so as not to be caught by the guides. Open the ADF and gently

    LCD Messages
    The following messages are displayed in the LCD when the machine performs a 
    function or if it encounters an error.
    This section describes the general messages and those related to copy and print 
    functions. For the messages related to fax functions, see Chapter 7, 
    “Troubleshooting,” in the Facsimile Guide.
    ADJUSTING 
    WAITING TO SCAN
    Cause The machine is not ready for copying because you have just connected the 
    power cord to the machine.
    Remedy Wait for a while. The machine cannot scan documents for copying immediately 
    after the power cord is connected.
    CHECK DOCUMENT
    Cause 1 There is a paper jam in the ADF.
    Remedy Remove the document you are trying to copy in the ADF. (See “Removing 
    Jammed Paper from the ADF,” on p. 9-7.)
    Make sure that the document is not too long or too short. (See “Document 
    Requirements,” on p. 3-1.)
    Cause 2 The ADF roller rotates without feeding documents.
    Remedy Fan the edge that will feed into the machine first, then tap the edge of multiple 
    page documents on a flat surface to even the stack.
    CHECK PAPER SIZE
    Cause The size of the paper in the cassette or multi-purpose feeder is different from 
    that of the paper specified in  of the Menu.
    Remedy Load the correct paper size or change  in  
    of the Menu. (See“Loading Paper,” on p. 2-3, or “Specifying the Paper Size,” on 
    p. 2-10.)
    Then reset the machine by opening the front cover and then closing it.
