    Note • Always remove all paper from the paper tray and straighten the stack when you add new paper. This 
    helps prevent multiple sheets of paper from feeding through the printer at one time and prevents paper 
    jams.
    • Please confirm that you have installed both a toner cartridge and a drum unit in the machine. If you have 
    not installed a drum unit or have installed the drum unit improperly, then this may cause a paper jam in 
    your Brother machine.

    Improving the print quality7
    If you have a print quality problem, print a test page first (see Print a test page on page 85). If the printout 
    looks good, the problem is probably not the printer. Check the interface cable or try the printer on another 
    computer.
    This section gives information on the following topics.
