    Troubleshooting paper handling 
    First, make sure that you are using paper that meets our 
    recommended paper specifications. See What kind of paper can I 
    use? in Chapter 1.
    ProblemRecommendation
    The printer does not 
    load paper.■If paper is in the paper tray, make sure it is straight.  
    If the paper is curled, you should straighten it before 
    printing. Sometimes it is helpful to remove the 
    paper, turn the stack over, and then put it back in 
    the paper tray.
    ■Reduce the amount of paper in the paper tray, and 
    then try again.
    ■Make sure that manual feed mode is not set  in the 
    printer driver.
    ■The pickup roller or separation pad needs to be 
    replaced.  Please call your dealer for a replacement.
    The printer does not 
    load paper from the 
    multi-purpose tray.■Fan the paper well and put it back in firmly.  
    ■Make sure you have chosen the manual feed mode 
    in the printer driver.  
    The printer does not 
    load envelopes.■The printer can load envelopes from the multi-
    purpose tray.  You must set up your application 
    software to print on the size of envelopes you are 
    using.  This is usually done in the page setup or 
    document setup menu of your software.  Please 
    see your software application manual for 
    instructions.
    Envelope is creased 
    after it is printed.■Open the face-up output tray, and push down the 
    blue tabs that are at the left-hand and right-hand 
    sides of the back of the printer.
    There is a paper jam.■Clear the jammed paper (see Paper jams and how 
    to clear them).
    ■The pickup roller or separation pad needs to be 
    replaced.  Please call your dealer for a 
    replacement.

    thicker setting.

    Paper may jam in the paper tray, inside the printer, in the face-up 
    output tray or where the paper comes out of the printer. Check where 
    the jam is and follow the instructions below to remove the jammed 
    paper. 
    If the error message still appears on the LCD after you remove the 
    jammed paper, there may be more paper jammed somewhere else.  
    Please check the printer thoroughly.   
    After you have removed all the jammed paper, open the top cover 
    and then close it again to start printing.
    Do not use the following:  
    ■Bent paper
    ■Moist paper
    ■Paper that does not meet specifications
    If the paper is misfeeding or a lot of pages are going through 
    at the same time when you print on small or thick paper, 
    change the paper thickness switches that are on the bottom 
    of the paper tray as follows.
