GP 16 Precautions for Disassembly

Observe the following precautions whenever servicing the machine.
• Be sure to unplug the machine from the outlet before attempting to service the machine.
• To reassemble the machine, reverse the order of disassembly unless otherwise specified.
• The basic rule is not to operate the machine anytime during disassembly. If it is absolutely nec-
essary to run the machine with its covers removed, use care not to allow your clothing to be
caught in revolving parts such as the gears, rollers and motor.
• Never touch the terminals of electrical parts or high-voltage parts such as the HVPS.
• Be sure to handle the Fuser Assy carefully as the unit is still hot for a while after the machine is
stopped.
• Always unplug connectors by holding the connector housing.
• Be sure to use the fuse of the specified rating.
• Do not forget to install the ground wire or ground plate to ensure positive conduction. Install the
screw with a toothed washer in the right position at reassembly.
Parts not to be touched
The following parts must not be removed, disassembled or adjusted.
• The parts where the mounting screws are painted red.
• ROS Unit. There are no adjustments or replaceable parts in the ROS unit. The ROS must be
replaced as a complete assembly.
Instructions for Handling the PWBs with MOS ICs
The following precautions must be observed when handling circuit boards with MOS (Metal
Oxide Semiconductor) ICs.
• During transportation or when in storage, new circuit boards must not be indiscriminately
removed from their protective conductive bags.
• Do not store or place circuit boards in a location exposed to direct sunlight.
• When it becomes absolutely necessary to remove a board from its conductive bag or case,
always place it on its conductive mat in an area as free as possible from static electricity.
During Replacement the PWBs with MOS ICs:
• Before unplugging connectors from the circuit boards, make sure that the power cord has been
unplugged from the power outlet.
• When removing a board from its conductive bag or case, do not touch the pins of the ICs or the
printed pattern. Place it in position by holding only the edges of the board.
• Before plugging connectors into the board, make sure that the power cord has been unplugged
from the power outlet.
