    When working on an item which is controlled as a spare part but the procedure therefore 
    is not described, observe carefully how the part is attached before removing the item.
    As a general rule, optional items are assumed to be removed from the equipment. How-
    ever, you may work with optional items attached if it does not disturb your work.

    1.1 Before starting service procedure
    - Start the procedure after turning off the power and removing the power cord from the outlet.
    - When performing the service operation around the FUSER UNIT, ensure that FUSER UNIT and its 
    surrounding area have cooled down sufficiently.
    - Pay sufficient attention to the parts during the procedure because they may be broken or may not 
    perform their functions properly if unreasonable force is applied.
    - Since various types of screws are used, ensure that the right screws are used in their right positions. 
    Use special caution not to confuse the screws for plastic and the ones for sheet metal, because 
    using the wrong type of screw may result in damage to the screw threads or other troubles.

    Confidential - Wear a wristband or the like as far as possible to remove static electricity of the human body.
    - Keep the front cover closed. Buzzer goes off when the machine is left powered on with the front 
    cover open for five minutes or longer to prevent the drum deterioration due to exposure to light.
    - When opening the front door in a removal/replacement operation, cover the drum to keep it from 
    being exposed to light.
    - Remove CASSETTE ASSY 250, DRUM CARTRIDGE, TONER CARTRIDGE and FUSER UNIT, 
    and put them in a place where they do not affect the procedure. (Note that the service procedures 
    can be performed with those parts in place depending on the target section of removal/replacement.)
